Using the Event Horizon Telescope, scientists obtained an image of the black hole at the center of the galaxy M87. The Event Horizon Telescope, a planet-scale array of eight ground-based radio telescopes forged through international collaboration, captured this image of the supermassive black hole in the center of the galaxy M87 and its shadow.

A yellow star in the center of galaxy RX J1242-11was bumped off course by another star and thrown into the path of a supermassive black hole. The enormous gravity of the black hole stretched the star until it was partially devoured and torn apart. These events are often known as "stellar tidal disruptions." The black hole was estimated to have had a mass of about 100 million times the Earth's Sun. In comparison, the star had a mass that was about equal to the Sun. In the pull of gravity battle between the two, the smaller star lost.

A binary black hole (BBH) is a system consisting of two black holes in close orbit around each other. ... Binary black hole mergers would be one of the strongest known sources of gravitational waves in the Universe.
Simulations predict that these mergers, unlike those of their stellar-mass counterparts, emit both gravitational waves and radiation – the latter originating in the hot, interstellar gas of the two colliding galaxies stirred by the black holes pair when they fall towards one another.

We are going to discover from the first prediction of a black hole(in 1784) to Albert Einstein and Subrahmanyan Chandrasekhar theories that helps us to understand the nature and types of black-holes and Sir Stephen hawking’s knowledge that leads us present-day progress of this most mysterious object in cosmos...
