Black hole - Wikipedia
Black holes typically form as part of a supernova event when massive stars collapse at the end of their life cycle. After a black hole has formed, it can grow by absorbing mass from its surroundings.
Black Holes - NASA Science
A black hole is so dense that gravity just beneath its surface, the event horizon, is strong enough that nothing – not even light – can escape. The event horizon isn’t a surface like Earth’s or even the Sun’s. It’s a boundary that contains all the matter that makes up the black hole.
What Are Black Holes? - NASA
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.
Black hole | Definition, Formation, Types, Pictures, & Facts | Britannica
Black hole, cosmic body of extremely intense gravity from which nothing, not even light, can escape. It can be formed by the death of a massive star wherein its core gravitationally collapses inward upon itself, compressing to a point of zero volume and infinite density called the singularity.
Black holes: Everything you need to know - Space
Black holes are real — and they're some of the most mysterious objects in space. Discover what they are, how they form, and why they captivate scientists.
Black Hole – Definition, Formation, Types, and Mysteries
Explore what a black hole is, how one forms, their types, structure, history, and the latest discoveries about these cosmic enigmas.
Black Holes | Center for Astrophysics | Harvard & Smithsonian
As gas flows around a black hole, it heats up, paradoxically making these invisible objects into some of the brightest things in the entire universe. As a result, we can see some black holes from billions of light-years away.
What is a black hole? | University of Chicago News
Black holes are regions in space where an enormous amount of mass is packed into a tiny volume. This creates a gravitational pull so strong that not even light can escape. They are created when giant stars collapse, and perhaps by other methods that are still unknown.
Black Hole 101 - Education
A black hole is a region in space where the force of gravity is so strong, not even light, the fastest known entity in our universe, can escape. The boundary of a black hole is called the event horizon, a point of no return beyond which we truly cannot see.
Black Holes | NSF - U.S. National Science Foundation
Black holes are extremely dense pockets of matter, objects of such incredible mass and miniscule volume that they drastically warp the fabric of space-time. Anything that passes too close, from a wandering star to a photon of light, gets captured.
