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.
Active. Astronomy Picture of the Day ( APOD) is a website provided by NASA and Michigan Technological University (MTU). It reads: "Each day a different image or photograph of our universe is featured, along with a brief explanation written by a professional astronomer ." [1] The photograph does not necessarily correspond to a celestial event on ...
The star field behind the black holes is being heavily distorted and appears to rotate and move, due to extreme gravitational lensing, as space-time itself is distorted and dragged around by the rotating black holes. [1] A binary black hole ( BBH ), or black hole binary, is a system consisting of two black holes in close orbit around each other.

These methods are specified in their notes. List of most massive black holes. Host or black hole name. Solar mass ( Sun = 1 × 10 0 ) Notes. (Theoretical limit) 2.7×1011. This is the maximum mass of a black hole that models predict, at least for luminous accreting SMBHs.
A rotating black hole is a black hole that possesses angular momentum. In particular, it rotates about one of its axes of symmetry. All celestial objects – planets, stars ( Sun ), galaxies, black holes – spin. [1] [2] [3] The boundaries of a Kerr black hole relevant to astrophysics. Note that there are no physical "surfaces" as such.
Supermassive black holes are classically defined as black holes with a mass above 100,000 ( 105) solar masses ( M☉ ); some have masses of several billion M☉. [12] Supermassive black holes have physical properties that clearly distinguish them from lower-mass classifications. First, the tidal forces in the vicinity of the event horizon are ...
