Picture of the Day: Messier 9 Star Cluster
NASA’s Hubble Space Telescope has taken this incredible picture of Messier 9, a globular star cluster located near the center of our galaxy. The cluster, located some 25,000 light years away, is too faint to be seen with the naked eye, but Hubble has captured more than 250,000 individual stars there. Globular clusters are believed to have emerged when the galaxy was quite young, and the stars that make up Messier 9 are calculated to be around twice as old as our sun.
