Difference between Supernovae and Black Hole

Key Difference: Supernovae is the plural form of supernova. The intense brightening stars that signals the start of the end is known as supernovae. Black hole is an object with a gravitational field where gravity is so strong that not even light can escape.

‘Supernovae’ is a plural form of supernova. Supernova more or less is an exploding star. Supernova, in a simple sentence, is the last stage of the life of a star. It is basically a procedure when a star is completely destroyed because it is not able to sustain its gravity anymore. When a supernova goes up in flames, a black hole is created. 

A black hole is an object with a gravitational field where gravity is so strong that not even light can escape. It is basically created by a collapsing star. A star over a certain mass i.e., about 8 times the mass of the sun is reaching the end of its life. One cannot spot/see a black hole directly with their bare eyes. The black hole can streak across the plane of the Milky Way at a velocity of 4 times that of the stars around it.

Description

(Dictionary.com)

The explosion of a star, possibly caused by gravitational collapse, during which the star's luminosity increases by as much as 20 magnitudes and most of the star's mass, is blown away at very high velocity, sometimes leaving behind an extremely dense core.

A theoretical massive object, formed at the beginning of the universe or by the gravitational collapse of a star exploding as a supernova, whose gravitational field is so intense that no electromagnetic radiation can escape.

Facts

  • Supernovas are huge stars that eventually explode.
  • When supernovas explode, they become massive black holes.
  • Supernovas also sometimes become quasars than black holes.
  • The creation of colorful nebulas is when supernovas explode and they shoot out billions atoms in every direction.
  • Some stars do not become supernovas, some become dwarf giants.
  • They were actually discovered by John Mitchell.
  • There are many different types.
  • They are incredibly dense.
  • They are noisy.
  • They slow down time.
  • They are the ultimate energy factories.
  • They limit the number of stars in the sky.
