April of 2015 saw the 25th anniversary of the launch of the much-loved Hubble Space Telescope. To kick off the celebrations, the site of an old favorite image has been revisited in high definition. The "Pillars of Creation" in the Eagle Nebula, taken in 1995, is one of Hubble's most famous pictures. For a sight of something that is majestic and beautiful, have a look at this hi def image of the Eagle Nebula taken in 2014.

On April 24, 1990 the Hubble Space Telescope was launched. This year is the 25th anniversary. Definitely worth celebrating. Watch for #Hubble25.

What does Hubble mean to you? For society? How has it inspired you? ESA and the Hubble people have a competition Ode to Hubble that anyone can join in. The main rules are (1) an original creation (2) inspired by the space telescope or one of its images of discoveries and (3) can be uploaded “ as a YouTube, Vine and Instagram video less than three minutes longâ€. I liked their two categories of under and over 25. The under 25s will have lived with Hubble all their lives. It may be more exciting for us oldies! Educators, this could be a super project for kids, bringing art, science, writing all together. Here's the page with the rules.

Happy face galaxy cluster. It's galaxy cluster SDSS J1038+4849 that seems to be smiling for the Hubble Space Telescope camera. The two orange eyes are bright galaxies. The apparent smile lines are gravitational lensing arcs. Lensing happens because the massive clusters bend the spacetime around them. This acts like a lens on the light coming from objects behind them. (Credit: NASA & ESA)

Here is splendid image of a spiral galaxy being twisted out of shape by an ongoing merger with a nearby small companion galaxy. The wonderful Hubble Space Telescope has given us many insights into the beauty and violence of the cosmos.

Hubble captures distant dusty galaxy NGC 4424 where a supernova exploded in 2012. In the same image is a smaller galaxy, an even more distant spiral galaxy seen edge-on to us. Another bright object looks more interesting than it is - it's bright because it's much closer to us, as it's a foreground star within our own Milky Way.

A young stellar object collapsing into a Sun-like star. Normally, it would be shrouded in dust, but in this Hubble image we're looking at one of its poles where a stellar jet has cleared a space.

Hubble image of the jewel-like center of the Messier 70 globular cluster. This star cluster orbits close to the center of the Milky Way, about 30,000 light years from us in the constellation Sagittarius. The cluster is almost seventy light-years in diameter. French astronomer Charles Messier discovered it in 1780.

Digital painting of the Flame Nebula (NGC 2024). Another work of art inspired by the Hubble Space Telescope. The nebula is in Orion, part of a star-forming region that includes the Horsehead Nebula. Alnitak, one of the three stars of Orion's belt provides the ultraviolet light that energizes the nebula.

The voting for the 25th Anniversary favorite Hubble image finished today. The public has spoken, and the winner is the iconic image of the Eagle Nebula Pillars, known popularly as the "pillars of creation". Protected within the dense gas are developing young stars. The "pillars" are about 100 AU in size. Since 1 AU is the distance from the Earth to the Sun, these things are *big*.

A snowstorm of galaxies imaged with the Hubble Space Telescope. But each of the snowflakes is a galaxy with billions of stars in it. This populous region of space is 5.4 billion light years away, and it isn't just one cluster of galaxies. It's a place where three galaxy clusters are merging.

Hubble's 25th anniversary image has been released -- star cluster Westerlund 2. It's a stellar nursery in the constellation Carina, and contains some of the brightest, hottest and most massive stars ever discovered. As is typical of stellar nurseries, it's surrounded by dust. Although this makes observing difficult (or impossible) in visible light, Hubble can also “see†in infrared which can penetrate the dust. The radiation and winds from the hot young stars erode the gas to form the pillars. (This is also happening the famous “Pillars of Creation,†Hubble's image of the Eagle Nebula.) In addition, the winds create shocks when they hit the walls of gas. This sets off a new wave of star formation. The red dots scattered around are stars that are still forming and not yet hot enough to establish hydrogen fusion. You can find out more about Starbirth by clicking here.

A number of professional astronomers were asked to choose their favorite Hubble image. Tanya Hill, Honorary Fellow of the University of Melbourne and Senior Curator (Astronomy) at Museum Victoria, chose this one of the Orion Nebula.. It's a splendid star-forming region, which you can just see in Orion's "sword" with the unaided eye. Tanya said, “I was a high school student when I first saw the nebula through a small telescope. What I saw on that long ago night was an amazingly delicate and wispy cloud of gas in black and white. One of the wonderful things that Hubble does is to reveal the colours of the universe.†You can find out more about the constellation Orion here.

The #Ode to Hubble competition for the under-25s (those born after Hubble was deployed) is from Halley Davies & Martin Hellmich of Canada. Their video Ode to Hubble - Hubble's Universe - is a delight, described as a "handmade multiformat animation about how we discovered the Universe with the help of the Hubble Space Telescope." It even includes a cameo of Edwin Hubble himself, if you watch carefully for the man with his pipe at the telescope. All the winners and runners-up of both Ode to Hubble compeitions are here.

A few days ago I put up a link to a picture of Westerlund 2, which was chosen as the 25th anniversary Hubble picture. But there's more. Here's a link to a page with a video that lets you zoom through stars and galaxies to reach the star cluster in close-up. Be sure to set it at full screen.

Space telescopes capture images we could never see otherwise. Yet Saturn - which you can see through an amateur telescope - is still one of the most beautiful sights of all. And even more so when imaged by the Hubble Space Telescope.

The Arches Cluster is billed as the most crowded place in the Milky Way. It's a star cluster 25,000 light years away in the constellation Sagittarius towards the Galactic Center. It's a young star cluster, a mere 2-4 million years old. If that doesn't sound much like a toddler to you, remember that the Solar System is 4.5 billion years old. But the Solar System is a nice suburban property, unlike the dense inner city of the Arches Cluster. Think of a sphere with the Sun at the center whose radius is the distance to our nearest neighboring star, Alpha Centauri. Alpha Centauri is not quite 4.4 light years away. In the Arches Cluster, a sphere of that size would contain over 100,000 stars.

Another beautiful tribute to Hubble. This one is by Davide Sigillò of Florence, Italy. He has painted M42 (the Orion Nebula) based on a Hubble Space Telescope image. The painting is oil on panel, using a palette knife technique. I'd love to see the actual painting.

I realized that I hadn't included a link to the winning video in the 25 & under section of the #Ode to Hubble competition. It's an original and quite delightful approach to the accomplishments of this wonderful telescope. Here is Hubble's Universe by Halley Davies and Martin Hellmich of Canada.

Here's a close-up of part of the Veil Nebula located 1500 light years away in the constellation Cygnus. This section is a little bit of the portion known as the Witch's Broom Nebula. NASA describes this Hubble image from 2007 as “the shattered remains of a supernova that exploded 5-10,000 years ago. The intertwined rope-like filaments of gas result from the enormous amounts of energy released as the fast-moving debris from the explosion ploughs into its surroundings and creates shock fronts. These shocks heat the gas to millions of degrees. The subsequent cooling of this material produces the brilliantly coloured glows. The different colours indicate emission from different kinds of atoms excited by the shock: blue shows oxygen, green shows sulphur, and red shows hydrogen.â€

We were all blown away by the magnificent pictures taken by the Hubble Space Telescope in 1999 - and rightly so. But thanks to space shuttle astronauts installing upgrades to Hubble, they've become even better over the years. These two images of the Quintuplet Cluster show the difference in imaging power between 1999 and 2015. The Quintuplet Cluster was named for its five brightest stars. It contains the Pistol Star which is the most luminous known star in the Galaxy. In a few million years it will end in a supernova, or even a hypernova.

Another super image from the Hubble Space Telescope. This is NGC 6565, a planetary nebula in the constellation Sagittarius. (Credit: ESA/Hubble & NASA) A dying star ejects its outer layers, and its stellar winds push them away to produce a planetary nebula. We see the nebula illuminated when the star's core is finally exposed and it produces UV radiation. This excites the surrounding gas and an array of colors is radiated. When the star shrinks to a white dwarf, its luminosity fades and the nebula fade from view.

Here is the Little Gem nebula (NGC 6818), a planetary nebula located in the constellation of Sagittarius, roughly 6000 light-years away from us. The rich glow of the cloud is a bit over half a light-year across. You can just see its star in the center. When stars like the Sun enter retirement, they shed their outer layers into space to create glowing clouds of gas called planetary nebulae. This ejection of mass is uneven, and planetary nebulae can have very complex shapes.

This new Hubble Space Telescope image of the Lagoon Nebula in the constellation Sagittarius has just been released by NASA/ESA. "Some of the most breathtaking views in the Universe are created by nebulae — hot, glowing clouds of gas. This new image shows the center of the Lagoon Nebula, an object with a deceptively tranquil name. The region is filled with intense winds from hot stars, churning funnels of gas, and energetic star formation, all embedded within an intricate haze of gas and pitch-dark dust."

The star WR 124 and its surrounding nebula M1-67 is located 15,000 light years away in the constellation Sagittarius. Not very romantic names, but it's a spectacular sight. The nebula has been created and lit up by the super-hot star which ejects hot gas at over 150,000 kilometers per hour. WR 124 is a mere infant at less than 10 million years old – our Sun is 5 billion years old. But the babe is bright, 150,000 times more luminous than the Sun.

Faint blue galaxies are revealed in this Hubble image taken twenty years ago. It's one of the deepest images of the sky ever taken with the space telescope. These galaxies turned out to be the most common class of objects in the universe.

The shimmering colours visible in this Hubble Space Telescope image show off the remarkable complexity of the Twin Jet Nebula (PN M2-9). The new image highlights the nebula’s shells and its knots of expanding gas in striking detail. Two iridescent lobes of material stretch outwards from a central star system. Within these lobes two huge jets of gas are streaming from the star system at speeds in excess of one million kilometers per hour.

Very occasionally, I've been fortunate enough to see the sky from a dark sky site. It's stunning - the Milky Way and so many stars. But it would really be something to see a sight like Messier 13. The image was taken by the Advanced Camera for Surveys on the Hubble Space Telescope, and it shows the core of the great globular cluster Messier 13. A globular cluster is just what its name implies: a star cluster which is globe-shaped because the gravity of the high density of stars pulls them together. You can read more about star clusters here.

Here is our neighbor the Andromeda galaxy. (Credit: NASA, ESA, J. Dalcanton, B.F. Williams, and L.C. Johnson (University of Washington), the PHAT team, and R. Gendler) Top: A mosaic of over four hundred images of the Andromeda galaxy. The view is 61,600 light years across. It includes 2,753 star clusters and images of 117 million stars in the galactic disk. Bottom left: An enlargement of what's in the box of the top view. It's 4,400 light years across. Bottom right: A view of six bright blue clusters, each square being 150 light years across. Wow! The Andromeda galaxy is 2.5 million light years away. However you can see it with the unaided eye in good conditions. It's the most distant object we can see without a telescope or binoculars.

Hubble image of Messier 96, a spiral galaxy just over 35 million light-years away in the constellation of Leo. It's about the same size as the Milky Way, but its shape has been somewhat distorted by the gravity of other nearby galaxies. (Image credit: ESA/Hubble & NASA and the LEGUS Team)

Messier 63, nicknamed the Sunflower Galaxy . The arrangement of the spiral arms is somewhat reminiscent of the center of a sunflower. The galaxy, which is located 27 million light years away in the constellation Canes Vanatici, was discovered in 1779 by Pierre Mechain. The spiral arms are very bright because they are starburst regions full of hot young stars and clusters. (Credit: ESA/Hubble & NASA)

Here's a wonderful Hubble image of spiral galaxy M96. It's 35 million light years away, and about the same size as our Milky Way. You should be able to see at least one more distant galaxy along the edge of the picture.

The Veil Nebula is one of the most exquisitely beautiful nebulae that we know of. It's a supernova remnant about 2100 light years from Earth in the constellation Cygnus. The supernova was the explosion of a massive star about 8000 years ago, and the remnant is now a brightly-colored cloud of glowing debris about 110 light years across. The name of the nebula comes from its gossamer-like filamentary structures. This is a new image from Hubble's Wide Field Camera 3.

Here is a gorgeous planetary nebula – it's name PK 329-02.2 doesn't match its beauty. The cloud of gas winding around a dying star is glowing blue. My favorite color! The nebula is in the southern constellation Norma, which is one of the constellations invented by 18th century French astronomer Nicolas-Louis de Lacaille. It isn't named after a lady, but is Latin for a right angle. It represents a set square. (Credit: ESA/Hubble & NASA)

Have a look at NGC 4639, a magnificent spiral galaxy that is over 70 million light-years away in the constellation Virgo. The spiral arms have bright blue jewel-like regions where new stars are forming. NGC 4639 is also an active galactic nucleus (AGN), which means that it has a massive black hole in its core which is actively consuming the surrounding gas. (Credit: ESA/Hubble & NASA)

Here is the beautiful galaxy Messier 94 in the constellation Canes Venatici. It's about 16 million light-years away. It has an unusual feature called a starburst ring. The ring around it is bright because there's a high rate of star formation, and bright young stars are lighting it up. (Credit: ESA/Hubble & NASA)

The Hubble Space Telescope has taken advantage of gravitational lensing to collect the largest sample yet of the earliest known galaxies in the Universe. Some of them formed just 600 million years after the Big Bang, so it allows astronomers to look back in time to a very young Universe.

Here we have a massive cluster of galaxies that's been used as a gravitational lens to magnify a much more distant galaxy. Wow! The bright yellow galaxies in the center belong to the cluster. The image of the galaxy that's farther away has been bent by the 'lens' into three images, each only a small red dot.

This galaxy with the catchy name of 2MASX J16270254+4328340 has merged with another galaxy. What looks like a fine mist is actually millions of new stars. Because of the gravitational disruption as the galaxies moved closer together, clouds of gas in the two them collapsed to form new stars. That would have been quite exciting, but most of the gas was used up then, so the new galaxy won't be producing new stars. The newly-formed stars will, like all stars, get redder with age, exhaust their fuel and die, without new ones to take their place.

Spiral galaxy NGC 7252 has an unusual nickname: Atoms for Peace Galaxy. US President Eisenhower in 1953 gave a speech advocating using nuclear power for peaceful purposes. This galaxy looks a bit like an atomic nucleus surrounded by electron orbits and so was given the nickname in honor of this speech. In the Hubble image you can see a pinwheel-shaped central disc – it's rotating in a direction opposite to the rest of the galaxy. That's probably the remnant of a galaxy collision and will disappear when the merger of two galaxies is completed. Dust and stars were thrown out by the initial collision and they make up the outer structures that look like loops or a representation of electrons in an atom. They're quite faint in this picture [Credit: NASA & ESA, Acknowledgements: Judy Schmidt (Geckzilla)]

A stunning Hubble picture of two galaxies merging. Evidence that the two galaxies are disturbing each other is the bridge of stars and gas and dust that their mutual gravity has made. The face-on spiral (NGC 3808A) has lots of young blue stars, evidence of a burst of star formation. The edge-on spiral (NGC 3808B) is twisted, has bridging material wrapped around and a polar ring. The interacting pair is known as Arp 87. Arp galaxies are “peculiar†and as a pair, these two certainly don't fit into the neat categories of galaxies. (You can find out about these in What Is a Galaxy? (Image Credit: NASA, ESA, Hubble Space Telescope; Processing: Douglas Gardner)

Here is a mosaic of two Hubble images taken in 1997 and 1998. It's Centaurus A, also known as NGC 5128, an elliptical galaxy in the constellation Centaurus. The blue light comes from hot newborn stars. The reddish-yellow color is due partly to hot gas, partly to older stars and partly to the scattering of blue light by dust. The latter is the same effect that produces bright orange sunsets on Earth. Credit: E.J. Schreier, (STScI) and NASA/ESA

This may look like a craggy fantasy mountaintop enshrouded by wispy clouds but it's a stellar nursery 7500 light years away in the constellation Carina. The NASA/ESA Hubble Space Telescope photograph captures the chaotic activity atop a pillar of gas and dust, three light-years high, which is being eaten away by the brilliant light from nearby bright stars. The pillar is also being assaulted from within, as infant stars buried inside it fire off jets of gas that can be seen streaming from towering peaks. The image from February 2010 marked the 20th anniversary of Hubble's launch and deployment into Earth orbit. Credit: NASA, ESA and M. Livio and the Hubble 20th Anniversary Team (STScI)

We wouldn't still be getting fantastic pictures from the Hubble Space Telescope if it weren't for the servicing missions on NASA's space shuttle. During Christmas Week in 1999, astronauts were busy replacing gyroscopes, which the telescope needs for controlling its orientation. Here Astronauts Steven L. Smith and John M. Grunsfeld are shown carrying out an EVA (extravehicular activity) on the telescope. By the way, the final servicing mission has be documented in glorious IMAX 3D in the movie Hubble 3D.

Mona, thank you for sending the link to the Hubble Christmas cards. They are beautiful. All your links are incredible. As a kid I followed everything about space exploration and breaking the sound barriers, etc. I miss that excitement. You've brought it back. Thanks so much.
Have a star studded Christmas. Hugs.

The Hubble Space Telescope was a fantastic project. Unfortunately, an error was introduced into its mirror as it was polished. The budget didn't include any testing, so the faulty mirror was on the telescope when it was launched. Fortunately, using the space shuttle, it was possible to make repairs to the telescope. In December 1993 the optics were corrected and a new camera installed. And on January 13, 1994 new photos were released. Here are comparison images for the spiral galaxy M100. There are two raw images that show the before and after. On the left is the image taken before the servicing mission. The effects of optical aberration in HST's 2.4-meter primary mirror blur starlight, smear out fine detail, and limit the telescope's ability to see faint structure. On the right we see the results of the modified optics in which the telescope can cleanly resolve faint structure as small as 30 light years across in a galaxy tens of millions of light years away.

Most galaxies have a spiral or elliptical structure, but about a quarter of them are irregular. Here is an example from the Hubble Space Telescope: NGC 5408. It was discovered by 1834 by John Herschel and long thought to be a planetary nebula. But it turns out to be a galaxy about 16 million light years away in the constellation Centaurus. It contains the “ultraluminous†X-ray source NGC 5408-A, which may be an intermediate-mass black hole. Credit: ESA/Hubble & NASA

This beautiful spiral galaxy NGC 5584 has played a key role in a new study that measures the expansion rate of the Universe to greater accuracy than ever before. Hubble can show individual stars in the galaxy, some of which are Cepheid variables, stars whose light varies in a way that we can calculate how far away they are. By studying many Cepheids in several galaxies the team has been able to refine our knowledge of this expansion rate, expressed as a number known as Hubble’s constant, to an accuracy of 3.3 percent.

Like the fury of a raging sea, this anniversary image from the Hubble Space Telescope shows a bubbly ocean of glowing hydrogen, oxygen, and sulphur gas in the extremely massive and luminous molecular nebula Messier 17. This is the Swan Nebula stellar nursery located about 5500 light-years away in the Sagittarius constellation. The wave-like patterns of gas have been sculpted and illuminated by a torrent of ultraviolet radiation from young, massive stars (which lie outside the picture to the upper left). The ultraviolet radiation is carving and heating the surfaces of cold hydrogen gas clouds. The warmed surfaces glow orange and red in this image. The image is roughly 3 light-years across. The colours in the image represent various gases. Red represents sulphur; green, hydrogen; and blue, oxygen. (Credit: European Space Agency, NASA, and J. Hester (Arizona State University))

NGC 1487 is a peculiar galaxy, some 30 million light years away in the constellation of Eridanus. It's peculiar because it's actually some old galaxies merging into a new galaxy. The original galaxies have lost their shapes, and stars and gas have been thrown out in the interaction. There are older yellow and red stars in the outer regions, but the blue - large areas of bright blue stars - are more noticeable. These are hot young stars that probably formed when the galactic merger triggered new star formation. (Image credit: ESA/Hubble & NASA)

This is WR 31a, a star of the kind known as a Wolf-Rayet star. This one is about 30,000 light years away in the constellation Carina. The blue bubble is a Wolf-Rayet nebula, formed around 20,000 years ago and expanding at 220,000 kilometers per hour (137,000 mph). Such massive stars don't live very long in stellar terms, and they end their lives in a supernova explosion. The material in it will then be recycled to enrich new stars. Credit: ESA/Hubble & NASA

This image is called the Hubble eXtreme Deep Field. It combines Hubble observations taken over a decade of a small patch of sky in the constellation of Fornax. It's the deepest image of the Universe ever made. It covers only a tiny fraction of the sky, but the long exposure reveals about 5500 galaxies, some of them so distant that we see them when the Universe was less than 5% of its current age.

Here is a collage of images taken of galaxy NGC 1512 taken by three Hubble Space Telescope cameras. Around the edge are images in one color or wavelength, going from near infrared through ultraviolet. In the middle the images have been combined into one picture to bring out detail in the ring of young star clusters that surrounds the core of the galaxy.

This gorgeous picture shows MACS J0416.1-2403 – MACS J0416 to its friends. It's an astounding 4.3 billion light years away in the constellation Eridanus (the River). It's two galaxy clusters on the verge of collisioon. This happened long ago and far away, because the Solar System was newly formed when the light from MACS J0416 began its journey. The Hubble Space Telescope wasn't the only one involved in getting this image. The galaxies and stars are by Hubble, but the diffuse blue shows the imprint of dark matter. The diffuse pink is radio emissions captured by the NRAO Jansky Very Large Array. Getting data in several wavelengths of light gives astronomers a better understanding of what is going on.

Wow! It's stars, stars, stars! More than half a million of them. There are a few blue foreground stars, but this is a massive star cluster in the center of our Galaxy. Tucked away in the middle of it is a supermassive black hole with the mass of around four million Suns. The Galactic Center is 27,000 light years away in the constellation Sagittarius and it's a pretty crowded place. Image credit: NASA, ESA, and the Hubble Heritage Team (STScI/AURA)

Is this cool or what? It's MACS J0717.5+3745, located 5.4 billion light years away in the constellation Auriga. This isn't a very glamorous name - and not much of a clue what we're seeing. A cluster of galaxies would be interesting enough, but this is four galaxy clusters colliding! The image combines data from three different telescopes. Credit Hubble with the galaxies and stars. The diffuse emission in blue is emitted by gas heated to millions of degrees - this was from NASA's Chandra X-ray Observatory. The diffuse emission in pink is data from the Jansky Very Large Array which shows radio emission from giant shock waves triggered by the merger.

I wonder if any of the bird constellations would fancy a Cosmic Caterpillar for breakfast. That's the nickname of IRAS 20324+4057 which is a protostar, a cosmic cloud that is contracting to make a new star. It's located about 4500 light years away in the constellation Cygnus the Swan.

NGC 7635 looks like a giant soap bubble, but it's actually a nebula nicknamed the Bubble Nebula. A brilliant star illuminates a cloud of gas and dust. It was discovered in 1787 by William Herschel and is about 8000 light years away in the constellation Cassiopeia. The pressure from the stellar winds of star SAO 20575, which is 10-20 times the mass of the Sun, forces the material around it into this bubble form. Image: Hubble Space Telescope

On Hubble's 20th anniversary there was a Google doodle in its honor. It showed up all around the world for anyone who did a Google search. Today marks the 26th anniversary of Hubble's deployment. In my last post I included a link to the birthday picture, the beautiful Bubble Nebula.

Look as this wonderful image of M106, a spiral galaxy in the constellation Canes Venatici. This image combines Hubble observations of M 106 with additional information captured by amateur astronomers Robert Gendler and Jay GaBany. Gendler combined Hubble data with his own observations to produce this stunning colour image. Credit: NASA, ESA, the Hubble Heritage Team (STScI/AURA), and R. Gendler (for the Hubble Heritage Team).

Here's the splendid spiral galaxy NGC 4394. It's about 55 million light years away in the constellation Coma Berenices, and is probably part of the Virgo Cluster of galaxies. William Herschel discovered it in 1784 – I think he'd be amazed and delighted if he could see this beautiful Hubble detail, instead of just as a fuzzy blob. Credit: ESA/Hubble & NASAÂ

I'm always enraptured by a beautiful spiral galaxy, and NGC 6814 is a grand design spiral galaxy, one of the prettiest. It has a very bright nucleus because it's a Seyfert galaxy, a type of galaxy that hosts an active supermassive black hole. The blue stars scattered around the galaxy are hot young stars, and show that there's been recent star formation. The dark dust lanes help to give the galaxy some extra definition. It's a beauty.

The star-forming region NGC 3603 contains one of the most impressive massive young star clusters in the Milky Way. Bathed in gas and dust the cluster formed in a huge rush of star formation thought to have occurred around a million years ago. The hot blue stars at the core are responsible for carving out a huge cavity in the gas seen to the right of the star cluster in NGC 3603's centre.

Hubble shows off a strange little galaxy. It's four and a half million light years away in Ursa Major, way out at the edge of our Local Group of galaxies: UGC 4879, an irregular dwarf galaxy. It's small and rather shapeless as well as being pretty much on its own. But since it doesn't have any neighbors with which to interact, astronomers are intrigued by its history of starbirth. It's a very old galaxy and a billion years ago star formation started up again – after a 9-billion year lull following its first active four billion years. (Credit: NASA & ESA)

One of the best-known Hubble Space Telescope images is of the Crab Nebula (M1) The image highlights the filaments of the expanding nebula which is a supernova remnant. The supernova explosion was recorded by Chinese astronomers (and others) nearly a thousand years ago. Yesterday they released a new image and it features the neutron star at the heart of the nebula, the remains of the massive star after the explosion. (If you're interesting in finding out more, Death of a Massive Star tells the story.) The new Hubble image of the Crab Nebula was made by combining three high-resolution images. To find the neutron star, look for pair of bright stars just to the right of center. It's the right-hand one of the pair. This amazing object has a mass about that of the Sun, but is a sphere about 32 km (20 mi) across. It's also spinning about 30 times a second (wow!). A Hubble press release says, The rapid motion of the material nearest to the star is revealed by the subtle rainbow of colors in this time-lapse image, the rainbow effect being due to the movement of material over the time between one image and another. As it spins it gives out bursts of radio waves - they come in pulses like the light from a lighthouse. This type of neutron star is called a pulsar.

Just released today is this "lonely" starburst galaxy MCG+07-33-027 around 300 million light years away. Normally, a galaxy doesn't produce more than a few new stars a year. If there are lots more than that, it's called a starburst. Since this is a face-on spiral galaxy, the spiral arms show up well, as does the starburst activity in them. Lots of hot young blue stars indicates considerable starbirth activity. There needs to be lots of gas available in a galaxy if it's to be making new stars. Then a starburst would need to be triggered in some way. Often an interaction with another galaxy is the trigger, but MCG+07-33-027 is fairly isolated, so it's not clear what set off this starburst.

Here is LEDA 36252 - a cosmic tadpole. Galaxies of this class are referred to as tadpoles because they have bright heads and elongated tails. This one is only 80 million light years away, but galaxies like this are uncommon in the nearby Universe. However they are quite common in the distant University. Remember that a telescope is like a time machine and we see distant objects as they were long ago. So it's probably that this tadpole shape is a stage that many galaxies pass through during their evolution. Credit: NASA, ESA, and D. Elmegreen (Vassar College), B. Elmegreen (IBM's Thomas J.

This is DEM L316A, a supernova remnant located 160,000 light years away in the Large Magellanic Cloud (LMC). The LMC is a satellite galaxy of the Milky Way and is visible in the southern hemisphere sky where it does indeed look like a cloud. The remnant is what's left after a violent explosion occurring on a white dwarf in a binary system. The material ejected travels through space at enormous speeds, heating up and energizing the gas in the space between the stars. That's what makes it glow. Credit: ESA/Hubble & NASA, Y. Chu

A dazzling - and at the same time mysterious - view of NGC 6611. It's a young open star cluster about 6500 light years from us, and part of the Eagle Nebula. The stars don't just look bright, they are bright. There are lots of young hot blue stars which make the surrounding gas glow. The cluster plus the nebula are known as Messier 16. There are also some very dark patches. These aren't holes in space, as was once thought, but areas of opaque dust that blot out the light from objects beyond them.

Here is a superb Hubble portrait of Alpha and Beta Centauri. The Alpha Centauri group - which also contains a third star Proxima Centauri - is the closest star system to the Earth. It's located in the constellation Centaurus the Centaur just over four light years away. Alpha and Beta Centauri form a beautifully bright pair in the southern skies.

A dramatic image from Hubble showing NGC 3918, an eye-shaped planetary nebula. It's located about 4900 light years away in the constellation Centaurus. Deep in the center of the gas cloud is a white dwarf. White dwarfs are tiny remnants of what were formerly red giants. When the stars run out of fuel, they may collapse into small, but compact, dwarfs. Credit: ESA/Hubble and NASA

The Large Magellanic Cloud (LMC) is a satellite galaxy of our Milky Way. N159 is a stellar nursery in the LMC. There are many hot young stars which emit strong ultraviolet light. That makes nearby hydrogen gas glow. The stars also have very strong stellar winds – you can see their handiwork in the ridges and arcs and filaments they carve out of the surrounding material. N159 is over 150 light years across and located around 160,000 light years away. Credit: ESA/Hubble & NASA

I love the glittering jewels of the Terzan 5 cluster. The cluster, say the astronomers, is most likely the relic of the very early days of the Milky Way. To make the image, they used data from one of Hubble's cameras, plus that from two ground-based telescopes, an adaptive optics instrument on the Very Large Telescope of the European Southern Observatory, and also an infrared camera at the Keck Telescope in Hawaii. The infrared was needed to penetrate clouds of dust, and adaptive optics sharpen ground-based images by compensating for changes in our atmosphere. Credit: NASA/ESA/Hubble/F. Ferraro

It's nebula IRAS 05437+2502 in the constellation Taurus. It was discovered in 1983 by IRAS - the Infrared Astronomical Satellite - which also found many other objects that were invisible from the ground. It's certainly an interesting and dramatic shape, but astronomers are not certain what's caused it. It seems to be a small isolate star formation region. However, the bright boomerang-shaped feature may tell a more dramatic tale. The interaction of a high velocity young star and the cloud of gas and dust may have created this unusually sharp-edged bright arc. Such a reckless star would have been ejected from the distant young cluster where it was born and would travel at 200 000 km/hour or more through the nebula. Credit: ESA/Hubble, R. Sahai and NASA

Have a look at this stunning image of NGC 6210, a planetary nebula in the constellation Hercules. A planetary nebula is created from shells of material ejected by a dying star. Our Sun will one day develop a planetary nebula, but that's billions of years into the future. Credit: ESA/Hubble and NASA

Here is NGC 278, a spiral galaxy in the constellation Cassiopeia. It's some 38 million light years away. The galaxy is currently undergoing an immense burst of star formation. This flurry of activity is shown by the unmistakable blue-hued knots speckling the galaxy’s spiral arms, each of which marks a clump of hot newborn stars. However, NGC 278’s star formation is somewhat unusual; it does not extend to the galaxy’s outer edges, but is only taking place within an inner ring some 6500 light-years across. [While] the galaxy’s center is bright, its extremities are much darker. Such a ring of star formation is called a nuclear ring. Credit: ESA/Hubble & NASA and S. Smartt (Queen's University Belfast)

Feast your eyes on NGC 299, an open star cluster located in the Small Magellanic Cloud. It isn't actually a cloud, of course, but rather a satellite galaxy of the Milky Way. The stars look like gemstones. Open clusters such as this are collections of stars weakly bound by the shackles of gravity, all of which formed from the same massive molecular cloud of gas and dust. Because of this, all the stars have the same age and composition, but vary in their mass because they formed at different positions within the cloud.

A section of a Hubble image of Westerlund 2 in near infra-red. It was released last year for Hubble's 25th birthday. The red dots scattered throughout the cosmic landscape captured in this . . . image are a rich population of forming stars that are still wrapped in their gas and dust cocoons. They have not yet ignited the hydrogen in their cores to light-up as stars. However, Hubble’s near-infrared vision allows astronomers to identify these fledglings. The brilliant blue stars seen throughout the image are mostly in the foreground. Credit: NASA, ESA, the Hubble Heritage Team (STScI/AURA), A. Nota (ESA/STScI), and the Westerlund 2 Science Team

M8, also known as the Lagoon Nebula, is located around 4500 light years away in the constellation Sagittarius. This image is a small region in the center of the nebula. The whole nebula is enormous, around 140 by 60 light years. (Our whole Solar System from the Sun out to the edge of the Oort Cloud has a radius of only two light years.) The clouds that you see are glowing from high-energy radiation. The massive stars hiding within the heart of the nebula give off enormous amounts of ultraviolet radiation, ionising the gas and causing it to shine colourfully, as well as sculpting the surrounding nebula into strange shapes.

NGC 2174 is a violent stellar nursery. Radiation from hot young stars make the surrounding gas glow, and also creates high velocity winds that blow the gas outwards. The nebula lies about 6400 light-years away in the constellation of Orion (The Hunter). respectively and the field of view is about 1.8 arcminutes across. Credit: ESA/Hubble & NASA

Hubble Spots a Celestial Bubble. This delicate shell seems to float serenely in the depths of space, but the apparent calm hides an inner turmoil. This is SNR B0509-67.5 (or SNR 0509 for short), the result of the blast wave from a supernova tearing through the interstellar medium. The bubble is the visible remnant of a powerful stellar explosion in the Large Magellanic Cloud (LMC), a small galaxy about 160 000 light-years from Earth. The bubble is 23 light years across and expanding at the rate of more than 18 million km/hr. Credit: NASA, ESA, and the Hubble Heritage Team (STScI/AURA). Acknowledgement: J. Hughes (Rutgers University)

There's a bridge between these two spiral galaxies, NGC 5257 and NGC 5258. It's made of gas and stars, showing a disruption that occurred when they moved close to each other. They will keep making these close passes over millions of years, and eventually merge into one galaxy. Credit: NASA, ESA, Hubble Space Telescope; Processing & Copyright: Chris Kotsiopoulos

This is spiral galaxy NGC 3274. It was discovered by William Herschel in 1783, but it's a distant and fairly dim galaxy so he wouldn't have seen much. Herschel would be astounded to see this image from the Hubble Space Telescope. It combines observations gathered in five different filters, bringing together ultraviolet, visible, and infrared light, so we really get a lot of detail. The galaxy is located over 20 million light-years away in the constellation Leo (The Lion). You can also see another galaxy PGC 213714 in the upper right hand corner of the picture. It's even farther away than NGC 3274. Credit: ESA/Hubble & NASA, D. Calzetti

Hubble pictures are amazing. How do you describe something even more amazing than amazing? This image of the Cartwheel Galaxy is stupendous! There are two other galaxies on the left. All three are part of a group of galaxies in the constellation Sculptor. They're around 400 million light years away. Image Credit: ESA, NASA, Hubble

The Eagle Nebula's "Pillars of Creation" is one of the best known of Hubble's photos - it was voted Number 1 in the 25th anniversary year. But this is a unfamiliar view of the Pillars of Creation. It was taken in the infrared so we're able to see through the dust and gas that usually hides it. Sublime photo.

On February 23, 1987 a supernova appeared in the Tarantula Nebula. Thirty years on the Hubble Space Telescope has a new image of SN1987A. [The supernova] is located in the centre of the image amidst a backdrop of stars. The bright ring around the central region of the exploded star is composed of material ejected by the star about 20,000 years before the actual explosion took place. The supernova is surrounded by gaseous clouds [whose] red colour represents the glow of hydrogen gas. Credit: NASA, ESA, and R.

This is galaxy UGC 12591. It's almost 400 million light years away in the Pisces-Perseus Supercluster. The supercluster is one of the biggest known structures in the use - it's made up of a chain of galaxy clusters that stretches some 250 million light years. UGC 12591 is massive, around four times the mass of the Milky Way. Galaxies rotate, but this one does it at high speed, up to 1.8 million kilometres per hour! Credit: ESA/Hubble & NASA

April 25, 2017 - the Hubble Space Telescope was deployed 27 years ago today. Happy birthday! One of the telescope's iconic images is the "Pillars of Creation", a star-forming part of the Eagle Nebula (M16). Here is another image of the Eagle's Pillars. This one was taken with Hubble's Wide Field Camera 3 (WFC3) in the near-infrared. The pillars are silhouetted against background stars. Credit: NASA/ESA/The Hubble Heritage Team (STScI/AURA)

Last year's birthday image was of NGC 7635, The Bubble Nebula. It's located 7,100 light-years away in the constellation Cassiopeia. Above and left of the Bubble's center is a hot, O-type star, several hundred thousand times more luminous and around 45 times more massive than the Sun. A fierce stellar wind and intense radiation from that star has blasted out the structure of glowing gas against denser material in a surrounding molecular cloud.

Where to begin when there are so many interesting things in this Hubble image . . . I suppose the showpiece is what looks like glitter spread across the image. This is the galaxy ESO 318-13. (Few galaxies have names, most are named by catalog references.) In the center of the galaxy is what looks like a star bright enough to be a supernova. However it's an ordinary star – just not in ESO 318-13, which is millions of light years away. It looks so bright because it's in our own Milky Way galaxy. In the upper right hand corner of the image is an elliptical galaxy. It's bright, but slightly fuzzy, objec. It's bigger than ESO 318-13, but also farther away. Galaxies have more space in them than stars, so we can often pick out objects behind a galaxy. If you look closely at the right hand side of ESO 318-18 you should be able to find a distant spiral galaxy. And you can probably pick out some more very distant galaxies scattered around the image, as well as Milky Way foreground stars. Credit: ESA/Hubble & NASAÂ

NGC 3597 was produced when two large galaxies collided. It's slowly evolving into a giant elliptical galaxy. This type of galaxy has become increasingly common over time.

This bright galaxy is near the equator of the Milky Way’s galactic disc, where the sky is thick with glowing cosmic gas, bright stars, and dark, obscuring dust. There's a lot of material to look through, so IC 342 is relatively difficult to spot and image, giving it the nickname: the “Hidden Galaxyâ€. A NASA/ESA Hubble Space Telescope image shows the very central region of the galaxy. There's a beautiful mixture of hot, blue star-forming regions, redder, cooler regions of gas, and dark lanes of opaque dust, all swirling together around a bright core. Credit: ESA/Hubble & NASA

This very deep image taken with the NASA/ESA Hubble Space Telescope shows the spiral galaxy NGC 4921 along with a spectacular backdrop of more distant galaxies. It was created from a total of 80 separate pictures through yellow and near-infrared filters. The galaxy reminds me of a swirl of whipped cream. Yum. Credit: NASA, ESA and K.
