Italian astronomers discover new star cluster

Astronomers from Italy report the detection of a new star cluster as part of the YMCA (Yes, Magellanic Clouds Again) survey. The newly discovered stellar grouping, designated YMCA-1, may be an old and remote star cluster ...

Hubble reveals a 'rediscovered' star cluster

This image shows the globular cluster NGC 6380, which lies around 35,000 light-years from Earth, in the constellation Scorpio (the Scorpion). Globular clusters are spherical groups of stars held together by gravity; they ...
