Black Holes Basics Types Anatomy Gallery On this page Introduction Stellar Supermassive Intermediate Primordial Types of Black Holes Astronomers generally divide black holes into three categories according to their mass: stellar-mass, supermassive, and intermediate-mass.


Astronomers close in on first direct view of a supermassive black hole Science & Technology

Nov 06, 2023 Astronomers have discovered the most distant black hole yet seen in X-rays, using NASA telescopes. The black hole is at an early stage of growth that had never been witnessed before, where its mass is similar to that of its host galaxy. This result may explain how some of the first supermassive black holes in the universe formed.

Astronomers Reveal First Visual Evidence of a Supermassive Black Hole

1 Closest. The nearest known black hole, called Gaia BH1, is about 1,500 light-years away. 2 Farthest. The most distant black hole detected, at the center of a galaxy called QSO J0313-1806, is around 13 billion light-years away. 3 Biggest. The most massive black hole observed, TON 618, tips the scales at 66 billion times the Sun's mass. 4 Smallest.

A black hole is an object in outer space whose the gravitational field is so strong that no matter or light can escape. Astronomers believe such regions can form from the collapse of massive stars. Researchers at Canadian institutions have contributed to theories supporting the existence of black holes. Artist's impression of black hole in space.

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.

A black hole is a dense, compact object whose gravitational pull is so strong that nothing can escape, not even light. Black holes are thought to result from the collapse of very massive stars. The gravity is so strong because their mass has been squeezed into a tiny space. The boundary in space around a black hole is called the "event horizon."

What Is Inside A Black Hole? WorldAtlas

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't get out.
