雙黑洞的雙曲世界
The Doubly Warped World of Binary Black Holes

如果一個黑洞看起來很奇怪，那麼兩個呢？在這幅詳細的電腦視覺圖中，來自一對環繞執行的超大質量黑洞周圍的吸積盤的光線穿過了由極端引力產生的扭曲時空。 模擬的吸積盤被賦予了不同的假色彩方案，紅色代表圍繞著 2 億太陽質量黑洞的吸積盤，藍色代表圍繞著 1 億太陽質量黑洞的吸積盤。 不過，就這些質量而言，這兩個吸積盤實際上都會在紫外線中發出大部分光線。 透過影片，我們可以同時看到每個黑洞的兩面。 在黑洞事件視界附近最內側的光環（稱為光子球）中，可以看到源自兩個黑洞的紅光和藍光。 在過去的十年中，雖然超大質量黑洞的凝聚仍未被發現，但黑洞碰撞產生的引力波已被探測到。 黑洞新世界：今天是美國國家航空航天局的黑洞周！
原文：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.
