1 mag 2023 · The new NASA animation shows 10 supersized black holes that occupy center stage in their host galaxies, including the Milky Way and M87, scaled by the sizes of their shadows. Starting near the Sun, the camera steadily pulls back to compare ever-larger black holes to different structures in our solar system.
6 mag 2024 · A backdrop of the starry sky as seen from Earth completes the scene. Tour an alternative visualization that tracks a camera as it approaches, falls toward, briefly orbits, and escapes a supermassive black hole. This immersive 360-degree version allows viewers to look around during the flight.

A black hole is a region of space packed with so much matter that its own gravity prevents anything from escaping — even a ray of light. Although we can’t see a black hole, the material around it is visible. Material falling into a black hole forms a disk, similar to a whirlpool in a bathtub drain. Matter swirling around a black hole heats up and e...
Stellar black holes form when the center of a very massive, dying star collapses in upon itself. This collapse may also cause a supernova, or an exploding star, that blasts the outer parts of the star into space. If the core remaining after the supernova is very massive, gravity completely collapses the core into a black hole with infinite density....
Stellar black holes are miniscule in comparison to the beasts that astronomers think lie at the centers of most galaxies. These black holes are supermassive — millions to billions of times the mass of our Sun. Prior to Hubble, astronomers did not have conclusive evidence that supermassive black holes existed in the universe. Thanks to Hubble and ot...
Many of Hubble’s first observations showed the effects of supermassive black holes on their immediate galactic environment. In 1990, shortly after launch, Hubble imaged a 30,000-light-year-long jet emanating from a galaxy known to be a prodigious emitter of radio light. With Hubble’s observations, astronomers had the data they needed to determine t...
From the wealth of Hubble data, astronomers now understand that black holes can have profound influences on the galaxy as a whole. For example, the jets from supermassive black holes can propel massive amounts of gas and dust into intergalactic space, thus ridding the galaxy of much-needed fuel for ongoing star formation. Or in the case of a 2015 r...
A black hole is an extremely dense object whose gravity is so strong that nothing, not even light, can escape it. Every object in space has an 'escape velocity': the minimum speed at which something must move to escape the object's gravitational field.
Astronomers tracked the orbits of several stars near the center of the Milky Way to prove it houses a supermassive black hole, a discovery that won the 2020 Nobel Prize. When very massive objects accelerate through space, they create ripples in the fabric of space-time called gravitational waves.
A black hole is a region of spacetime where gravity is so strong that nothing, not even light and other electromagnetic waves, is capable of possessing enough energy to escape it. Einstein's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
8 set 2020 · A black hole is an astronomical object with a gravitational pull so strong that nothing, not even light, can escape it. A black hole’s “surface,” called its event horizon, defines the boundary where the velocity needed to escape exceeds the speed of light, which is the speed limit of the cosmos.
