By analyzing the data from ESA's XMM-Newton and Gaia satellites, astronomers have investigated a young star cluster known as NGC 2264. Results of the study, published November 16 on the arXiv pre-print repository, shed more ...
Astronomers from the University of Toronto and the University of Arizona have provided the first direct evidence that an intergalactic "wind" is stripping galaxies of star-forming gas as they fall into clusters of galaxies. ...
