Star clusters are wonderful test beds for theories of stellar formation and evolution. One of the key roles they play is to help astronomers understand the distribution of stellar masses as stars form (in other words, how ...

Using the Very Large Telescope (VLT), astronomers from Chile have performed a chemical analysis of a sample of stars in the globular cluster NGC 6553. Results of this study, available in a paper published March 12 on the ...
Astronomy & Astrophysics publishes the work of researchers from the University of Vienna, who have found a river of stars, a stellar stream in astronomical parlance, covering most of the southern sky. The stream is relatively ...
