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.

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.

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.
Quote:
[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.

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!

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.
