The other is part of what astronomers are calling a black-hole triple, the first known instance of a three-body system that includes a black hole, which is not supposed to be part of the mix, according to standard astrophysics.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Black holes are the bottomless pits of gravity decreed by Einstein\u2019s theory of general relativity more than a century ago. Astronomers now know that there are millions of them just in our own galaxy, the Milky Way, the gravestones of stars that imploded and collapsed beyond limit. And every galaxy appears to harbor a supermassive black hole \u2014 which is millions to billions of times as massive as our sun \u2014 at its center.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">The killer black hole was first noticed five years ago, when astronomers spotted a flare from the center of a distant galaxy 215 million light-years from Earth. The flare came from a star that had wandered too close to the galaxy\u2019s supermassive black hole, a \u201ctidal disruption event\u201d named AT1910qix.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Over the next five months, gravitational forces <a class=\"css-yywogo\" href=\"https:\/\/www.nytimes.com\/2020\/10\/17\/science\/astronomy-black-hole-at1910qix.html\" title=\"\">ripped the star apart<\/a> and stretched its innards into a ring encircling the black hole. Half of this material fell into the black hole; the other half began drifting away in an expanding disc.<\/p>\n<\/div>\n<aside class=\"css-ew4tgv\" aria-label=\"companion column\"\/><\/div>\n<div data-testid=\"companionColumn-1\">\n<div class=\"css-53u6y8\">\n<p class=\"css-at9mc1 evys1bk0\">Now, however, that leftover debris has drifted so far out from the black hole that it is interfering with another star.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Every 48 hours, this star crashes through the remnant disc on its way around the black hole, creating a flash of violent X-rays and other radiation. An international team of astronomers led by Matt Nicholl of the Queen\u2019s University, Belfast, has been following the action with an array of space telescopes, including the Chandra X-ray Observatory, the Hubble Space Telescope and the Neutron Star Interior Composition Explorer.
