Supermassive Black Hole

In News 

  • Recently, Indian researchers spotted a rare supermassive black hole.

About 

  • The monster black hole is about one billion light years away from the Earth.
    • The black hole in question was captured, spewing a jet of radiation and particles in one direction, unlike others that fire jets in opposite directions.
  • Supermassive black holes create powerful jets of radiation and particles. They are located at the center of galaxies.
  • The supermassive black hole occupies the center of the RAD 12 galaxy, which is elliptical or egg-shaped. 
    • RAD 12 is in the process of merging with another galaxy, RAD 12b, in the next one billion years.
      • RAD 12b, which is also elliptical, is bigger and brighter than RAD 12.

Implications 

  • This discovery may help scientists study why star formation does not occur in elliptical galaxies.
    •  Star formation requires extremely cooled gas, usually forged in a cloud of interstellar gas and dust. 
  • It opens new avenues for star formation research
  • Researchers speculate that jets fired by supermassive black holes will likely suppress future star formation.

Black hole

  • It is an astronomical object with a gravitational pull so strong that nothing, not even light, can escape it. 
  • A black hole’s “surface,” called its event horizon, defines the boundary where the velocity needed to escape exceeds the speed of light, which is the speed limit of the cosmos. 
  • Matter and radiation fall in, but they can’t get out.
