Explore globular clusters, ancient spherical collections of millions of stars tightly bound by gravity. Uncover their secrets and cosmic significance.
Messier 30 is a densely packed cluster of ancient stars located about 27,000 light-years away within the constellation Capricornus. It is notable for having undergone a core collapse, where its central region became extremely dense, creating a compact stellar core.
Also known as the 'Cat's Eye Cluster,' M4 is one of the closest globular clusters to Earth, located about 7,200 light-years away. It contains hundreds of thousands of stars, including the first observed pulsar in a globular cluster, making it a fascinating object for astronomers.
Messier 2 (M2) is a spectacular globular cluster containing over 150,000 stars, located about 33,600 light-years away. It is easily visible with binoculars and small telescopes from Earth.
