Astronomers have inspected the brightest star of a globular cluster known as 47 Tucanae (other designation NGC 104). Results of the study, published August 3 on arXiv.org, provide important insights into the properties and ...
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 ...
Based on the data from the Hubble Space Telescope (HST), astronomers have conducted a detailed spectroscopic and photometric study of two Type II globular clusters (GCs), namely NGC 1261 and NGC 6934. Results of the research, ...
Palomar 5 is a unique star cluster. In a paper published today in Nature Astronomy, an international team of astrophysicists led by the University of Barcelona show that distinguishing features of Palomar 5 are likely the ...
