Visualization: Near a Black Hole and Disk

Explanation: What would it look like to plunge into a monster black hole? This image from a supercomputer visualization shows the entire sky as seen from a simulated camera plunging toward a 4-million-solar-mass black hole, similar to the one at the center of our galaxy. The camera lies about 16 million kilometers from the black hole’s event horizon and is moving inward at 62% the speed of light. Thanks to gravity’s funhouse effects, the starry band of the Milky Way appears both as a compact loop at the top of this view and as a secondary image stretching across the bottom. Move the cursor over the image for additional explanations. Visualizations like this allow astronomers to explore black holes in ways not otherwise possible.

说明: 想像一下，如果坠入一个巨型黑洞会是什么样子？这张由超级电脑视觉化生成的影像展示了一台模拟相机拍摄的整个天空景象，这台相机正朝着一个质量约为400万个太阳质量的黑洞俯冲而去，这个黑洞类似于我们银河系中心的黑洞。相机位于距离黑洞的事件视界约1,600万公里处，并以62%的光速向内移动。由于重力的欢乐屋效应（funhouse effects），银河系的星带在图像顶部呈现为一个紧凑的环状结构，而在底部则以拉伸的方式呈现出来。将游标移到图像上可以获得更多的解释。像这样的视觉化技术使天文学家能够以其他方式无法实现的方式探索黑洞。
