Monster black hole that could eat 30 billion suns discovered

In News
  • Astronomers have now discovered the biggest black hole in the universe, one that could consume not a million but billions of suns like the one in our Solar System.
Discovery of Black hole
  • Being termed one of the biggest black holes discovered by astronomers, it is estimated to have over 30 billion times the mass of our Sun.
  • In simple terms, this black hole could fit an equivalent of 30 billion suns in it, making it one of the most interesting discoveries of our times.
  • Researchers said that this is the first black hole found using gravitational lensing.
  • Researchers used supercomputer simulations to simulate light from a distant galaxy travelling through the Universe, each simulation had a black hole of a different mass.
  • The path taken by the light in one simulation matched the path seen in actual images captured by the Hubble Space Telescope, leading to the discovery of an ultramassive black hole in the foreground galaxy.
  • They simulated light travelling through the Universe hundreds of thousands of times, with each simulation including a different mass black hole.
Black Hole
  • A black hole is formed from the death of a star with such a high gravitational field that the matter gets squeezed into the small space under it, trapping the light of the dead star.
  • The gravity is so strong due to the matter being squeezed into a tiny space. Since no light can get out, people can't see black holes.
  • According to Nasa, there are two main classes of black holes that have been extensively observed.
  • The Stellar-mass black holes with three to dozens of times the Sun’s mass is spread throughout our Milky Way galaxy, while supermassive monsters weighing 1,00,000 to billions of solar masses are found in the centers of most big galaxies.
