Ordinary (baryonic) matter make up all physical objects in existence, from stars to the cores of black holes. But until now, scientists had only been able...
A supermassive black hole in the center of the ultra-luminous quasar SMSS J215728.21-360215.1 (J2157-3602 for short) devours a mass equivalent to our Sun...
ESA’s Gaia mission has released the largest catalogue ever of Milky Way stars. It includes the positions on the sky for approximately 1.7 billion stars,...
Using a quasar microlensing technique, astronomers claim to have found a large population of unbound planets — with masses ranging from Moon to Jupiter...
New findings from a team of astronomers at the University of California, San Diego, and elsewhere increase understanding of how powerful winds generated...
