如果一个黑洞看起来很奇怪，那么两个呢？在这张详细的计算机可视化图中，来自一对绕轨道运行的超大质量黑洞周围的吸积盘的光线穿过由极端重力产生的扭曲时空。模拟的吸积盘被赋予了不同的虚假配色方案，红色代表环绕2亿太阳质量黑洞的盘，蓝色代表环绕1亿太阳质量黑洞的盘。然而，对于这些质量，两个吸积盘实际上会以紫外线的形式发出大部分光线。这段视频让我们同时看到每个黑洞的两面。从两个黑洞发出的红光和蓝光可以在靠近视界的最内层光圈（称为光子球）中看到。在过去的十年里，黑洞碰撞产生的引力波实际上已经被探测到，尽管超大质量黑洞的合并仍然没有被发现。黑洞新世界：这是NASA的黑洞周！

If one black hole looks strange, what about two? Light rays from accretion disks around a pair of orbiting supermassive black holes make their way through the warped space-time produced by extreme gravity in this detailed computer visualization. The simulated accretion disks have been given different false color schemes, red for the disk surrounding a 200-million-solar-mass black hole, and blue for the disk surrounding a 100-million-solar-mass black hole. For these masses, though, both accretion disks would actually emit most of their light in the ultraviolet. The video allows us to see both sides of each black hole at the same time. Red and blue light originating from both black holes can be seen in the innermost ring of light, called the photon sphere, near their event horizons. In the past decade, gravitational waves from black hole collisions have actually been detected, although the coalescence of supermassive black holes remains undiscovered.
