What is Supernova

  • A supernova is the explosion of a star. It is the largest explosion that takes place in space.
  • Supernovas are often seen in other galaxies.It is difficult to see it in our own Milky Way galaxy because dust blocks our view.
  • A supernova happens where there is a change in the core, or center, of a star. A change can occur in two different ways, with both resulting in a supernova.
  • The first type of supernova happens in binary star systems. Binary stars are two stars that orbit the same point.
  • One of the stars, a carbon-oxygen white dwarf, steals matter from its companion star. Eventually, the white dwarf accumulates too much matter.
  • Having too much matter causes the star to explode, resulting in a supernova.
  • The second type of supernova occurs at the end of a single star’s lifetime. As the star runs out of nuclear fuel, some of its mass flows into its core.
  • Eventually, the core is so heavy that it cannot withstand its own gravitational force.The core collapses, which results in the giant explosion of a supernova.
  • The sun is a single star, but it does not have enough mass to become a supernova.
