gravity: The force that attracts anything with mass, or bulk, toward any other thing with mass. When an unlucky star wanders too close to a supermassive black hole in the centre of a. black hole: A region of space having a gravitational field so intense that no matter or radiation (including light) can escape. "This observation rules out a class of solutions that have been proposed theoretically and gives us a stronger constraint on what happens to gas around a black hole," said Berkeley graduate student Kishore Patra in a statement. Black holes are some of the most powerful objects in the Universe. By the time they are repeatedly scattered, the X-Rays have stretched to ultraviolet or even optical wavelengths. The near-spherical shape means there is plenty of gas blocking our view of the black hole, and therefore sapping the energy of the X-rays that should be being produced from black hole's accretion disk. They estimate its radius as 100 times that of the Earth's orbit.īy November 6, 2019, a small amount of polarization was detected, indicating the cloud had thinned sufficiently so we were seeing light from the asymmetric structure closer to the black hole itself. From this, the authors inferred the cloud is close to spherically symmetric – the first time we've seen a tidal disruption event closely enough to draw conclusions about the shape. The new paper reports negligible levels of polarization in light at the event's brightest point. Astronomers concluded that while most of the star was getting spaghettified, a powerful wind spread some of its material into a cloud.
