It’s an image produced by light that has orbited the black hole one or more times before escaping. 6 00:01:27.720 --> 00:01:32.459 This oval, centered on the camera’s direction of travel, shows the entire simulated sky. 7 00:01:34.461 --> 00:01:38.264 Camera position and orientation relative to the black hole. 8 00:01:38.264 --> 00:01:42.068 For the camera, time slows compared to that of a faraway observer. 9 00:01:42.469 --> 00:01:48.508 The camera is aiming at the photon ring’s far side. It’s now moving so fast that the simulation slows for a better view. 10 00:01:50.944 --> 00:01:56.282 The camera’s speed causes light sources directly ahead to brighten greatly. 11 00:01:57.484 --> 00:02:03.423 The camera begins its 10-minute plunge to the event horizon. 12 00:02:06.993 --> 00:02:09.829 The camera hits the event horizon ... 13 00:02:09.829 --> 00:02:11.998 now. 14 00:02:12.365 --> 00:02:17.470 Light from the outside universe still shines in, but can never leave. 15 00:02:19.305 --> 00:02:24.410 The camera is destroyed. Microseconds later, it reaches the singularity. 16 00:02:25.478 --> 00:02:30.783 A closer view shows just how layered and intricate the photon ring is. 17 00:02:45.131 --> 00:02:50.436 Each band is a distorted image of the gas disk layered between the background sky. 18 00:02:50.837 --> 00:02:56.142 Successive bands are thinner, produced by photons that have taken an additional trip around the black hole before reaching the camera. 19 00:03:06.352 --> 00:03:14.294 Due to the camera’s speed, the entire sky appears to shift progressively forward. The sky is shrinking before our eyes. 20 00:03:28.908 --> 00:03:34.214 On a typical laptop, computing this simulation would have taken more than a decade. 21 00:03:34.948 --> 00:03:40.253 The Discover supercomputer at NASA’s Goddard Space Flight Center performed the feat in 5 days ... 22 00:03:40.286 --> 00:03:44.591 ... using only 0.3 percent of its processing power. 23 00:04:16.756 --> 00:04:21.060 NASA
