PKS 2131-021 is a quasar and a BL Lacerate object, [2] producing an astrophysical jet. [ 3 ] lt is located in the constellation Aquarius and classified as a blazar , a type of active galactic nucleus whose relativistic jet points in the direction towards Earth .
[68] [69] [70] An entry in the Pet Simulator series, Pet Simulator X sparked controversy among the Roblox community when the developers, Big Games, integrated non-fungible tokens into the game, the first ever instance of such on the platform. [‡ 9] [71] The game has been played over 5 billion times as of January 2023. [72]
The supermassive black hole at the core of Messier 87, here shown by an image by the Event Horizon Telescope, is among the black holes in this list.. This is an ordered list of the most massive black holes so far discovered (and probable candidates), measured in units of solar masses (M ☉), approximately 2 × 10 30 kilograms.
A black hole with the mass of a car would have a diameter of about 10 −24 m and take a nanosecond to evaporate, during which time it would briefly have a luminosity of more than 200 times that of the Sun. Lower-mass black holes are expected to evaporate even faster; for example, a black hole of mass 1 TeV/c 2 would take less than 10 −88 ...

The Event Horizon Telescope (EHT) is a telescope array consisting of a global network of radio telescopes.The EHT project combines data from several very-long-baseline interferometry (VLBI) stations around Earth, which form a combined array with an angular resolution sufficient to observe objects the size of a supermassive black hole's event horizon.
In order to reproduce all the known outbursts, the rotation of the primary black hole is calculated to be 38% of the maximum allowed rotation for a Kerr black hole. [10] [4] The companion's orbit is decaying via the emission of gravitational radiation and it is expected to merge with the central black hole within approximately 10,000 years. [11 ...
Artist's rendering of the accretion disc in ULAS J1120+0641, a very distant quasar containing a supermassive black hole with a mass two billion times that of the Sun [1] The Chandra X-ray image is of the quasar PKS 1127-145, a highly luminous source of X-rays and visible light about 10 billion light-years from Earth.
