What is a Supernova?

  • a giant explosion in outerspace
  • a explosion from a dead star
  • colors from gases of a star
  • a natural burst of light outside the atmosphere
  • A gas explosion

HOW IS A SUPERNOVA CREATED?

  • A supernova is created by a star that has died
  • the core of a star falls and creates a giant explosion
  • many colors appear because of the gases the star releases

Why is there a huge explosion after a star dies?

  • The stars core collapses to explode
  • The star releases a huge amount of energy
  • The energy bursts and it creates the colors
  • The star gas explodes

How long does a supernova last?

  • A supernova last for a couple days
  • They usually last for about 2 days
  • The longest recorded time is a week

WHY DO STARS DIE?

  • because the energy that they had stored has worn out so they explode
  • stars are like other living things so they die and but living things don't explode

DOES A STAR BECOME A SUPERNOVA OR A BLACK HOLE?

  • main sequence, such as our own Sun, this mostly involves combing hydrogen to form helium
  • the energy that the reactions produce is enough to support their mass against gravity
  • So it becomes a supernova, well stars have a choice to be a BH or a supernova
