In this flight toward a supermassive black hole, labels highlight many of the fascinating features produced by the effects of general relativity along the way. This supercomputer visualization tracks a camera as it approaches, briefly orbits, and then crosses the event horizon — the point of no return — of a supersized black hole similar in mass to the one at the center of our galaxy.

All monster black holes are not equal. Watch this video to see how they compare to each other and to our solar system. The black holes shown, which range from 100,000 to more than 60 billion times our Sun’s mass, are scaled according to the sizes of their shadows – a circular zone about twice the size of their event horizons. Only one of these colossal objects resides in our own galaxy, and it lies 26,000 light-years away. Smaller black holes are shown in bluish colors because their gas is expected to be hotter than that orbiting larger ones. Scientists think all of these objects shine most intensely in ultraviolet light.

Learn more about the best-known black hole systems in our galaxy and its neighbor, the Large Magellanic Cloud. This visualization presents 22 X-ray binary systems that host confirmed black holes at the same scale, with their orbits sped up by about 22,000 times. The view of each system reflects how we see it from Earth. Star colors ranging from blue-white to reddish represent temperatures from 5 times hotter to 45% cooler than our Sun. In most of these systems, a stream of matter from the star forms an accretion disk around the black hole. In others, like the famous system called Cygnus X-1, the star produces a hefty outflow that is partly swept up by the black hole’s gravity to form the disk. The accretion disks use a different color scheme because they sport even higher temperatures than the stars. The largest disk shown, belonging to a binary called GRS 1915, spans a distance greater than that separating Mercury from our Sun. The black holes themselves are shown larger than in reality using spheres scaled to reflect their masses.Credit: NASA's Goddard Space Flight Center and Scientific Visualization StudioMusic: "Event Horizon" from Gravity.

Watch eight model stars stretch and deform as they approach a virtual black hole 1 million times the mass of the Sun. The black hole’s gravity rips some stars apart into a stream of gas, a phenomenon called a tidal disruption event. Others manage to withstand their close encounters. These simulations show that destruction and survival depend on the stars’ initial densities. Yellow represents the greatest densities, blue the least dense.

Explore how the extreme gravity of two orbiting supermassive black holes distorts our view. In this visualization, disks of bright, hot, churning gas encircle both black holes, shown in red and blue to better track the light source. The red disk orbits the larger black hole, which weighs 200 million times the mass of our Sun, while its smaller blue companion weighs half as much. Zooming into each black hole reveals multiple, increasingly warped images of its partner. Watch to learn more. Credit: NASA’s Goddard Space Flight Center/Jeremy Schnittman and Brian P.

This visualization shows gravitational waves emitted by two black holes (black spheres) of nearly equal mass as they spiral together and merge. Yellow structures near the black holes illustrate the strong curvature of space-time in the region. Orange ripples represent distortions of space-time caused by the rapidly orbiting masses. These distortions spread out and weaken, ultimately becoming gravitational waves (purple). The merger timescale depends on the masses of the black holes. For a system containing black holes with about 30 times the sun’s mass, similar to the one detected by LIGO in 2015, the orbital period at the start of the movie is just 65 milliseconds, with the black holes moving at about 15 percent the speed of light. Space-time distortions radiate away orbital energy and cause the binary to contract quickly. As the two black holes near each other, they merge into a single black hole that settles into its "ringdown" phase, where the final gravitational waves are emitted. For the 2015 LIGO detection, these events played out in little more than a quarter of a second. This simulation was performed on the Pleiades supercomputer at NASA's Ames Research Center.

This movie shows a complete revolution around a simulated black hole and its accretion disk following a path that is perpendicular to the disk. The black hole’s extreme gravitational field redirects and distorts light coming from different parts of the disk, but exactly what we see depends on our viewing angle. The greatest distortion occurs when viewing the system nearly edgewise. As our viewpoint rotates around the black hole, we see different parts of the fast-moving gas in the accretion disk moving directly toward us. Due to a phenomenon called "relativistic Doppler beaming," gas in the disk that's moving toward us makes that side of the disk appear brighter, the opposite side darker. This effect disappears when we're directly above or below the disk because, from that angle, none of the gas is moving directly toward us.When our viewpoint passes beneath the disk, it looks like the gas is moving in the opposite direction. This is no different that viewing a clock from behind, which would make it look like the hands are moving counter-clockwise.CORRECTION: In earlier versions of the 360-degree movies on this page, these important effects were not apparent. This was due to a minor mistake in orienting the camera relative to the disk. The fact that it was not initially discovered by the NASA scientist who made the movie reflects just how bizarre and counter-intuitive black holes can be!
