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. Matter and radiation fall in, but they can ...
A black hole is a region of spacetime wherein gravity is so strong that no matter or electromagnetic energy (e.g. light) can escape it. [2] Albert Einstein 's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. [3][4] The boundary of no escape is called the event horizon.
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.
6 min read. Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole's gravity. And ...
A black hole is a region of universe where gravity is so outrageously strong that nothing, not even light, can escape. Once something enters a black hole by crossing an invisible boundary known as ...
Black holes, explained. 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 holes fascinate both the public and scientists ...

Black Holes Black holes are among the most mysterious cosmic objects, much studied but not fully understood. These objects aren’t really holes. They’re huge concentrations of matter packed into very tiny spaces. A black hole is so dense that gravity just beneath its surface, the event horizon, is strong enough that nothing – not even […]
At the center of our galaxy, a supermassive black hole churns. Learn about the types of black holes, how they form, and how scientists discovered these invis...
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. Most black holes are the condensed remnants of a massive star, the collapsed core that remains ...
A black hole is a place in space containing an enormous amount of mass packed very tightly together. And it has the capacity to draw in more mass all the time. These objects have so much mass — and therefore gravity — that nothing can escape them, not even light. That makes them some of the most extreme objects in the universe.
Nothing is darker than a black hole. A black hole is an area of such immense gravity that nothing—not even light—can escape from it. Black holes form at the end of some stars’ lives. The energy that held the star together disappears and it collapses in on itself producing a magnificent explosion. Here’s where things get crazy.

The only true "image" of a black hole ever created came out in 2019, when astronomers used the Event Horizon telescope — a network of dishes spanning the entire Earth — to snap an image of ...
The short answer: A black hole is an area in space where gravity is so strong that light can not get out. Explanation: If a ball is thrown upwards from the surface of the Earth it reaches a certain height and then falls back. The harder it is thrown, the higher it goes.
Astronomers cannot observe black holes directly, but see behaviors in other objects that can only be explained by the presence of a very large and dense object nearby. The effects can include materials getting pulled into the black hole, accretion disks forming around the black hole, or stars orbiting a massive but unseen object.
This black hole is 6.5 billion times the mass of the Sun and resides at the center of the galaxy M87. Credit: Event Horizon Telescope Collaboration. Black holes are some of the most fascinating and mind-bending objects in the cosmos. The very thing that characterizes a black hole also makes it hard to study: its intense gravity.

Researchers spot black hole feeding at 40x its theoretical limit. Similar feeding events could explain the rapid growth of supermassive black holes. This artist’s illustration shows a rapidly ...
A black hole is a region in space where the pulling force of gravity is so strong that light is not able to escape. The strong gravity occurs because matter has been pressed into a tiny space. This compression can take place at the end of a star’s life. Some black holes are a result of dying stars. Because no light can escape, black holes are ...
