Black hole - Wikipedia
网页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. [2] Einstein's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

What Are Black Holes? - NASA
网页2020年9月8日 · 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.
NASA Animation Sizes Up the Universe’s Biggest Black Holes
网页2023年5月1日 · The black hole at the heart of our own galaxy, called Sagittarius A* (pronounced ay-star), boasts the weight of 4.3 million Suns based on long-term tracking of stars in orbit around it. Its shadow diameter spans about half that of Mercury’s orbit in our solar system. The animation shows two monster …
Black Hole Basics - Science@NASA
网页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.
Black Hole Anatomy - Science@NASA
网页The main light source from a black hole is a structure called an accretion disk. Black holes grow by consuming matter, a process scientists call accretion, and by merging with other black holes. A stellar-mass black hole paired with a star may pull gas from it, and a supermassive black hole does the same from stars that stray too close.
