The Best Science Photos of the Week - March 17, 2012

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.

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.

Located roughly 270 million light-years from Earth in the constellation of Centaurus (The Centaur), a bright constellation in the southern sky, ESO 381-12, also known as PGC 42871, is categorised as a lenticular galaxy — a hybrid galaxy type that shares properties with both spiral galaxies and elliptical galaxies.
