NASA and ESA release a Hubble view of Messier 3 that will have you saying, "My God, it's full of stars!"
The term "globular cluster" doesn't invoke visions of beauty all on its own, but the actual objects out in space are some of the most stunning the Hubble Space Telescope has ever laid eyes on.
The European Space Agency described the Messier 3 globular cluster, the subject of a newly released Hubble view, as "one of the most beautiful of them all." It's 8 billion years old and contains half a million stars.
Globular clusters are spherical collections of stars. Messier 3 is a bit unusual, though. It's packed with a whole bunch of variable stars, ones that change in brightness over time. Scientists have spotted 274 of these twinklers in Messier 3.
