Markarian 421 : Supermassive Black Hole

NASA’s IXPE Mission unveils twisted mysteries of the Supermassive Black Hole Markarian 421.

  • Markarian 421 is a supermassive black hole firing a jet of high-energy particles aimed directly at Earth.
  • It is about 400 million light-years away from the earth
  • It is located in the constellation Ursa Major.
  • Supermassive black hole have a mass greater than about 50,000 times the mass of our sun.
  • These black holes are far too large to have formed from the gravitational collapse of a single star.
  • These are always found at the centre of a galaxy and almost all galaxies have a supermassive black hole at its centre.
  • Imaging X-ray Polarimetry Explorer (IXPE) is an international collaboration between NASA and the Italian Space Agency.
  • It studies the most extreme and mysterious objects in the universe – supernova remnants, supermassive black holes, and dozens of other high-energy objects.
  • It is the first satellite dedicated to measuring polarized X-rays from objects, such as neutron stars and supermassive black holes, to reveal previously hidden details of the universe.
