NASA’s Goddard Space Flight Center and Jeremy Schnittman have created this visualization of a black hole and how its immense gravity distorts our view if we were near it. In this simulation, matter has collected around the black hole called an accretion disk. These are made of dust, gas and even shredded stars. The object's strong magnetic field forms bright knots in the disk. Light and dark "lanes" in the disk are caused by portions of the disk traveling slower than other portions. To a viewer, the disk would appear brighter on the left side than it does on the right. That's because it moves toward us (looking head on) and the right side moves away from us. The innermost ring is called the "photon ring" made of multiple rings that grow thinner as light circles the hole several times before it finally escapes. Inside that is the black hole's shadow — which is twice the size of the event horizon. Once inside the event horizon, nothing can escape.
