Russian astronomers have performed a detailed study of one of the ultraluminous X-ray sources (ULXs) in the galaxy UGC 6456. Results of the research, presented in a paper published November 20 on arXiv.org, suggest that this ...
Using NASA's Chandra X-ray Observatory, astronomers from Pennsylvania State University (PSU) and the California Institute of Technology (Caltech) have investigated IRAS 09002-473, an embedded cluster of stars in the Vela ...
Astronomers at MIT and elsewhere have used a massive cluster of galaxies as an X-ray magnifying glass to peer back in time, to nearly 9.4 billion years ago. In the process, they spotted a tiny dwarf galaxy in its very first, ...
