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.

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.
