Black hole

A place in space where gravity pulls so much that even light cannot get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.

How Do Scientists Know They Are There?

A black hole cannot be seen because strong gravity pulls all of the light into the middle of the black hole. But scientists can see how the strong gravity affects the stars and gas around the black hole. Scientists can study stars to find out if they are flying around, or orbiting, a black hole. When a black hole and a star are close together, high-energy light is made. This kind of light cannot be seen with human eyes. Scientists use satellites and telescopes in space to see the high-energy light.

First Image of Black hole

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.

Black Hole Eats Star

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.

Black hole Merger

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...
