Blackhole

Blackhole

Astronomers all over the world were astounded early this year by a strange and extraordinarily bright flash of light that originated halfway across the universe.

Major Findings:

  • Now that the powerful beam's origin has been discovered, it is pointed directly at Earth by a supermassive black hole that is consuming a star.
  • The light jet was 1,000 trillion times brighter than the sun.
  • Researchers from several institutions, including one from India, worked together to track the activity caused by the black hole, which is located 8.5 billion light-years from Earth.

Regarding Black Holes:

  • In a black hole, the gravitational pull is so strong that not even light can escape.
  • Because the substance is compressed into such a small area, the gravity is extremely intense. When a star is dying, this may take place.

How Black Holes Develop:

  • The smallest black holes, according to scientists, are those that originated at the Big Bang.
  • Stellar black holes are created when the core of a massive star collapses or collapses in on itself. When this occurs, a supernova results. A supernova is a star that explodes and sends a portion of the star into space.
  • Supermassive black holes are believed by scientists to have formed simultaneously with the galaxy they are in.

Visibility:

  • They are invisible because no light can pass through them.
  • Specialized space telescopes can aid in the discovery of black holes.
  • In fact, the gases circulating about aid in producing their appearances.

Size:

Black holes can vary in size.

  • The smallest black holes, according to scientists, are as small as a single atom, relatively small but possess the bulk of a big mountain.
  • The mass of a "stellar" black hole, which is a different type, may be up to 20 times greater than the mass of the sun.
  • Supermassive black holes are the biggest and have combined masses more than one million suns.
  • Sagittarius A is the name of the supermassive black hole in the centre of the Milky Way galaxy.
  • It would fit inside an extremely huge ball that could accommodate a few million Earths and has a mass equivalent to around 4 million suns.
