In 2012, a microquasar, a radio burst emanating from a smaller black hole was detected in the Andromeda Galaxy. The progenitor black hole is located near the galactic center and has about 10 M☉.
May 27, 2010 · Learn how the supermassive black hole at the center of Andromeda galaxy changes over time and why it is dimmer than expected. See the X-ray images of the black hole's outburst in 2006 and its jet streaming out.
Nov 30, 2017 · A distant source 2.6 billion light years away, previously thought to be in Andromeda, is revealed to be a pair of supermassive black holes in close orbit. Using X-ray and optical data, astronomers find evidence of gravitational waves and periodic variations in the light from this unusual system.
Jun 12, 2013 · NASA's Chandra X-ray Observatory found 26 possible black holes in Andromeda, the largest number in a galaxy outside of the Milky Way. These black holes are mostly located near the galaxy center and some are associated with globular clusters.
Jun 12, 2013 · Using X-ray data from NASA's Chandra Observatory, astronomers have identified 26 black hole candidates in Andromeda, the nearest galaxy to the Milky Way. The black holes are mostly in the central region of Andromeda, where the galaxy has a larger bulge and more stellar mass than the Milky Way.
Our neighboring galaxy's unusual core. The images and illustration reveal that the Andromeda Galaxy's (M31's) core is composed of a ring of old, red stars and a newly discovered disk of young, blue stars. The disk is trapped within a supermassive black hole's gravitational field.
See the sharpest visible-light image ever made of the 100-million-solar-mass black hole at the core of M31, or the Andromeda galaxy. Learn how young blue stars formed and survive near the black hole and how astronomers study this phenomenon.
