Galaxies don't normally look like this. NGC 6745 actually shows the results of two galaxies that have been colliding for only hundreds of millions of years. Just off the above digitally sharpened photograph to the lower right is the smaller galaxy, moving away. The larger galaxy, pictured above, used to be a spiral galaxy but now is damaged and appears peculiar. Gravity has distorted the shapes of the galaxies.

This new NASA/ESA Hubble Space Telescope image shows a gathering of four cosmic companions. This quartet forms part of a group of galaxies known as the Hickson Compact Group 16, or HCG 16 u2014 a galaxy group bursting with dramatic star formation, tidal tails, galactic mergers and black holes.

Messier 9 cluster: First discovered by Charles Messier in 1764, the globular cluster Messier 9 is a vast swarm of ancient stars located 25,000 light-years away, close to the center of the galaxy.   The cluster’s innermost stars have never been individually resolved - until now.   Hubble has captured the details of over 250,000 stars within it.  Most of Messier 9′s stars are nearly ten billion years old — twice the Sun’s age.
