A dazzling queen of ancient Egypt was the inspiration for the constellation Coma Berenices. It's small and dim, but contains the Galactic North Pole and multitudes of galaxies. Coma Berenices – Berenice's Hair

The Coma cluster of galaxies contains thousands of galaxies and is one of the densest clusters known. The cluster's light take hundreds of millions of years to get here and millions of years to go from one side of it to the other. Credit & Copyright: Dean Rowe

This globular cluster M53 was imaged by the Hubble Space Telescope in 2008. There are so many stars that their mutual gravity pulls them together into a globular shape. This one is 60,000 light years from the Galactic Center and about 58,000 light years from us. You can find out more about the two types of star cluster and how they differ from each other and from galaxies in Galaxy or Star Cluster?

NGC 4394 is a splended barred spiral galaxy. It's 53.8 million light years away in Coma Berenices. William Herschel discovered it in 1784 and I'm sure he would have loved to see the beautiful detail that we can see today. The galaxy is probably a member of the Virgo Cluster of galaxies in the heart of the Virgo Supercluster. The barred spiral has bright spiral arms emerging from the ends of a bar that cuts through the galaxy's central bulge. Dotted around the arms are young blue stars, fuzzy bright stellar nurseries, and filaments of dark cosmic dust.

Here is the representation of Berenice's Hair as shown in the 19th century Urania's Mirror. It looks more than a bit strange to me. What do you think?

The The Mice Galaxies (NGC 4676A right, B left) are two spiral galaxies 290 million light years away in Coma Berenices whom are in the process of colliding and merging. Their name refers to the long tails produced by tidal action.

Here are a pair of galaxies in the constellation Coma Berenices: NGC 4302 and NGC 4298 in a Hubble Space Telescope photo. They're about 55 million light years away and both are dusty spiral galaxies. But what a contrast! We see NGC 4302 edge-on, with prominent dust lanes that block some of the light and make the starlight appear redder than it should be. Its smaller companion galaxy NGC 4298 which is more nearly face-on to us. You can see both the bluer light of young stars and the galactic core of yellow more mature stars.

Amazing! So far away and inconceivably huge.

The constellation Leo used to have a tail. Ptolemy (the most influential 2nd century astronomer and author of The Almagest) considered the clump of faint stars at the end of Leo's tail as the tuft of the tail. However at some point it became the separate constellation of Coma Berenices. There's a great cluster of galaxies located in there, and it's known as the Coma Cluster of galaxies. Here is a grand face-on spiral galaxy located within the Coma Cluster. Image credit: NASA
