(Phys.org)—Located some 87,000 light years away, a dense globular cluster named Messier 54 (also known as NGC 6715) is a real gold mine for astronomers. Recently, an international team has discovered dozens of new variable stars in this cluster, improving the stellar census of Messier 54. The findings were presented in a paper published online on May 23 on the arXiv pre-print server.
