Stellar mass black holes swarm in Milky Way’s core
Space telescopes find clues to the birth of supermassive black holes
Astrophysicists have taken a major step forward in understanding how supermassive black holes formed. Using data from three of NASA’s space telescopes, Italian researchers have found the best evidence to date that the direct collapse of a gas cloud produced supermassive black holes in the early universe.
Disco lights from a galaxy cluster seen with multi-spectral eyes
MACS J0717, some 5.4 billion light-years away from Earth in the constellation of Auriga (The Charioteer), is the result of four galaxy clusters colliding. This image is a combination of observations in visible light, X-rays and radio waves from the NASA/ESA Hubble Space Telescope, NASA’s Chandra X-ray Observatory, and the NRAO Jansky Very Large Array.
