1ES 2344+514. Ton 618 (this quasar has possibly the biggest black hole ever found, estimated at 66 billion solar masses) [1] 3C 371. 4C +37.11 (this radio galaxy is believed to have binary supermassive black holes) [2] AP Lib. S5 0014+81 (said to be a compact hyperluminous quasar, estimated at 40 billion solar masses) [3]
In astrophysics, an event horizon is a boundary beyond which events cannot affect an observer. Wolfgang Rindler coined the term in the 1950s. [1] In 1784, John Michell proposed that gravity can be strong enough in the vicinity of massive compact objects that even light cannot escape. [2] At that time, the Newtonian theory of gravitation and the ...
Spaghettification. Tidal forces acting on a spherical body in a non-homogeneous gravitational field. In this diagram, the gravitational force originates from a source to the right. It shows both the tidal field (thick red arrows) and the gravity field (thin blue arrows) exerted on the body's surface and center (label O) by a source (label S).
Common Blue Violet (Viola sororia) color variant. Viola sororia is a short-stemmed, herbaceous perennial plant that grows in well-drained and shady habitats. [ 5 ] This 15–25 centimeters (6–10 in) wide violet has glossy, heart-shaped leaves and are topped with purple flowers with white throats. The lower three petals are hairy and the stem ...
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.
Stellar black hole. A stellar black hole (or stellar-mass black hole) is a black hole formed by the gravitational collapse of a star. [1] They have masses ranging from about 5 to several tens of solar masses. [2] They are the remnants of supernova explosions, which may be observed as a type of gamma ray burst.
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.
The definition of type B-type stars was the presence of non-ionized helium lines with the absence of singly ionized helium in the blue-violet portion of the spectrum. All of the spectral classes, including the B type, were subdivided with a numerical suffix that indicated the degree to which they approached the next classification.
