Black hole - Wikipedia
The first black hole known was Cygnus X-1, identified by several researchers independently in 1971. [8][9] Black holes typically form 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.
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
The black hole is 6.5 billion times more massive than the Sun. This picture was the first direct visual evidence of a supermassive black hole and its shadow. The ring is brighter on one side because the black hole is rotating, and thus material on the side of the black hole turning toward Earth has its emission boosted by the Doppler effect.
Black holes: Everything you need to know - Space
Black holes are some of the strangest and most fascinating objects in the universe. They're extremely dense, with gravitational forces so strong, that nothing, not even lights, can escape once...
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.
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.
James Webb telescope confirms a supermassive black hole running away ...
JWST peered at the glowing trail of stars left behind by a candidate runaway supermassive black hole deep in space, revealing new insights after other telescopes looked at the event.
Black Hole Explained: The Science, Discovery, and Mysteries of the ...
Learn what a black hole is, how it forms, and how astronomers detect it. Understand the science behind black holes and their role in shaping the universe.
Understanding Black Holes - sciencenewstoday.org
Black holes challenge our assumptions not just about matter and energy, but about causality, time, and the knowability of the universe. They are nature’s way of keeping secrets—vaults with no key, paradoxes wrapped in silence.
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.
