天文学家首次探测到打嗝黑洞，并意外发现围绕它运行的第二个黑洞

天文学家首次探测到一个黑洞的“打嗝”现象，并意外发现了一个围绕其运行的第二个黑洞。这个黑洞位于距离地球8亿光年的星系中心，质量高达5000万个太阳。每隔8.5天，它会向宇宙空间喷射出大量气体，这一现象源自于黑洞周围的吸积盘。科学家们通过研究认为，这些气体喷发可能与一个较小的黑洞有关，这个次级黑洞在一个倾斜的轨道上运行，扰动气体并引发喷发。这一发现不仅丰富了我们对黑洞的认识，也预示着可能存在一个全新的极端双星黑洞族群。

astronomers have detected for the first time a phenomenon known as a "burping" black hole and unexpectedly discovered a second, smaller black hole orbiting around it. This black hole, located at the center of a galaxy 800 million light-years away from Earth, has a mass of up to 50 million suns. Every 8.5 days, it ejects a large amount of gas into space, an event originating from the accretion disk surrounding the black hole. Scientists believe that these gas ejections may be related to a smaller black hole that orbits on an inclined path, disturbing the gas and triggering the ejections. This discovery not only enriches our understanding of black holes but also suggests the possible existence of an entirely new class of extreme binary black holes.
