In yet another validation of Einstein’s theory of general relativity, precise measurements of a star’s light as it orbits the black hole at the center of the Milky Way show the predicted gravitational redshift.
A 360-dergree visualization of the Milky Way’s core from the perspective of its central supermassive black hole shows the chaotic motion of nearby stars and gas clouds.
A voracious quasar at the heart of a galaxy 1.1 billion light years away is blowing huge bubbles in space, giving the host galaxy the shape of a teacup.
Astronomers studying light from the extremely early universe have discovered 83 quasars, indicating supermassive black holes were commonplace early on.
The remains of a destroyed star in a disc of shredded debris around a supermassive black hole showed the hole was spinning at more than half the speed of light.
The Hubble Space Telescope has spotted the brightest quasar ever seen in the early universe, an active galactic nucleus shining 11 trillion times brighter than the Sun.
New computer simulations show tangled magnetic fields in jets streaming away from supermassive black holes may be creating powerful electric fields and currents accelerating particles to enormous energies
Astronomers are getting their best views yet of supermassive black holes in the cores of colliding galaxies moving toward mergers, rapidly growing as they gorge on stellar debris
