Ww J discussed on 24 Hour News
One else was struck. At suspect is now in custody. WW J news time nine twenty two. Start date October twenty fourth. The problem with black holes is that they're black. They don't produce any detectable energy at all. So astronomers find and study black holes by observing their effects on this stuff around them. They pull it nearby stars, for example, and they sometimes feed on gas and dust which glows brightly as it spirals toward a black hole. One of the most spectacular affects is when a black hole rips apart a star known as a tidal disruption event. It can be as bright as a supernova it can shoot out. Bright jets have charged particles, and it can shine for years. The star has to pass a black hole at just the right distance to be disrupted. If the star goes directly toward the black hole. It can be completely gobbled up with fewer fireworks too far. And it gets away cleanly at just the right distance though. The black hole rips the star into a blazing stream of hot gas. Gas much of the gas enters orbit around the black hole. Blazing brightly before it's devoured. The rest of it escapes. The black hole forming bright streamers that slowly cool and fade in the last decade or two astronomers have seen perhaps several dozen of these events. Most of them have been produced by supermassive black holes. These monsters sit in the hearts of galaxies. They way millions or billions of times the mass of the sun. But an event reported this year appear to be caused by a rare middleweight black hole more about that tomorrow..
