December 4, 2008--Hundreds of thousands of stars in the globular cluster M13 are frozen in time by a composite image taken from NASA's Hubble Space Telescope.

The snow globe of stars can be seen in the winter sky in the Hercules constellation.

M13, which is 25,000 light-years away, houses more than 100,000 stars. It is so crowded in the center of the cluster that stars often collide, forming new stars called blue stragglers. The red light is from aging stars expanding as they cool.

This hotbed of celestial activity is just one of nearly 150 globular clusters surrounding the Milky Way.
