如果一颗恒星离黑洞太近会发生什么？黑洞可以撕裂它——但如何撕裂呢？问题并不是巨大的引力本身，而是恒星之间的引力差异造成了毁灭。在这段动画视频中，你首先看到一颗恒星正在接近黑洞。随着轨道速度的增加，恒星的外层大气在最接近时被撕裂。这颗恒星的大部分大气分散到太空深处，但一些继续围绕黑洞运行并形成吸积盘。然后动画带你进入吸积盘，同时看着黑洞。包括引力透镜的奇怪视觉效果，你甚至可以看到圆盘的远端。最后，你看沿着自转轴的一个喷流。理论模型表明，这些喷流不仅会排出高能气体，还会产生高能中微子——其中一种可能最近在地球上被发现。几乎超空间：随机APOD生成器

What happens if a star gets too close to a black hole? The black hole can rip it apart -- but how? It's not the high gravitational attraction itself that's the problem -- it's the difference in gravitational pull across the star that creates the destruction. In the featured animated video illustrating this disintegration, you first see a star approaching the black hole. Increasing in orbital speed, the star's outer atmosphere is ripped away during closest approach. Much of the star's atmosphere disperses into deep space, but some continues to orbit the black hole and forms an accretion disk. The animation then takes you into the accretion disk while looking toward the black hole. Including the strange visual effects of gravitational lensing, you can even see the far side of the disk. Finally, you look along one of the jets being expelled along the spin axis. Theoretical models indicate that these jets not only expel energetic gas, but also create energetic neutrinos -- one of which may have been seen recently on Earth.
