These objects can tear apart whole stars and …The smaller black hole would serve as a precise probe of the spacetime around the bigger black hole, revealing whether it warps and twists exactly as the Kerr metric dictates. An affirmative result would cement the case that black holes are what general relativity predicts, Yunes says. "But you have to wait for LISA."The doomed star, named N6946-BH1, was 25 times as massive as our sun. It began to brighten weakly in 2009. But, by 2015, it appeared to have winked out of existence. By a careful process of elimination, based on observations researchers eventually concluded that the star must have become a black hole.

As the orbit shrinks, the pair gets closer to merging. Supermassive black holes millions to billions of times the mass of our Sun lie at the heart of most galaxies, and astronomers are eager to know how these behemoths came to be.It's also powered by the hungriest and fastest-growing black hole ever seen — one that consumes the equivalent of over one sun's mass a day. The quasar, J0529-4351, is located so far from Earth ... What is a black hole? Black holes are extremely dense pockets of matter, objects of such incredible mass and miniscule volume that they drastically warp the fabric of space-time. Anything that passes too close, from a wandering star to a photon of light, gets captured. Most black holes are the condensed remnants of a massive star, the collapsed ... Black holes are: Small. Despite how massive black holes can be, they are quite compact. If our Sun were to turn into a black hole, it would measure less than two miles across. Sagittarius A* could fit within Mercury’s orbit, and M87’s supermassive black hole is about three times the size of Pluto’s orbit. Powerful.
