靠近黑洞的恒星会发生什么？如果这颗恒星直接撞击一个巨大的黑洞，那么这颗恒星就会完全坠入黑洞——一切都消失了。然而，更有可能的是，这颗恒星离得足够近，以至于黑洞的引力把它的外层吸走，或者破坏了这颗恒星。这样，恒星的大部分气体就不会落入黑洞。这些恒星潮汐破坏事件可以像超新星一样明亮，越来越多的恒星潮汐破坏事件被自动巡天发现。在这幅特色艺术家的插图中，一颗恒星刚刚经过一个巨大的黑洞，释放出继续绕其轨道运行的气体。黑洞周围由气体和尘埃组成的圆盘的内缘被破坏事件加热，在恒星消失后很长一段时间内可能会发光。黑洞新世界：这是NASA的黑洞周！

What happens to a star that goes near a black hole? If the star directly impacts a massive black hole, then the star falls in completely -- and everything vanishes. More likely, though, the star goes close enough to have the black hole's gravity pull away its outer layers, or disrupt, the star. Then, most of the star's gas does not fall into the black hole. These stellar tidal disruption events can be as bright as a supernova, and an increasing amount of them are being discovered by automated sky surveys. In the featured artist's illustration, a star has just passed a massive black hole and sheds gas that continues to orbit. The inner edge of a disk of gas and dust surrounding the black hole is heated by the disruption event and may glow long after the star is gone. Hole New Worlds: It's Black Hole Week at NASA!
