Near the center of the Milky Way Galaxy sits an immense object that astronomers call Sagittarius A*. This "supermassive" black hole may have grown in tandem with our galaxy, and it's not alone. Scientists suspect that similar ...

(Phys.org)—Two teams working independently have found evidence of the existence of missing Baryonic matter—particles that link galaxies together. One team was made of members from the Institute of Space Astrophysics, ...
Investigating the history of our cosmos with a large sample of distant 'active' galaxies observed by ESA's XMM-Newton, a team of astronomers found there might be more to the early expansion of the universe than predicted ...
