Supernova

• Have you ever wonder what happens when a star Die ?.
• there are tons of different types of stars
  • blue giants
  • white dwarfs
  • red giants
  • the sun is considers to be GV2 Main Sequence Yellow Dwarf
• All starts are unbelievably large.
• more than 1 million planet earth could fit inside our sun.
• this giant size causes tremendous gravity that’s constantly trying to come crushing inside the star.
• this push everything the star is made of down towards its core.
• the pressure and density inside a star would be truly unimaginable.
• even microscopic atoms can’t stand this pressure.
• hydrogen the most common atom is everywhere even inside a star.
• the pressure inside a star is so strong that it strips hydrogen its electrons leaving bare nucleus.
• these bare nucleus of hydrogen combine with other bare nuclei fusing together forming more heavy elements like helium or oxygen.
• in physics this is know as nuclear fusion.
• and these heavy elements have tons of extra energy that they are not used to.
• so they release or emit the energy as radiation.
• this radiation spills into space, and some of it becomes the light that hits the planet earth.
• to mention that this powerful energy flowing outwards prevent the  start gravity from crushing it.
• a star is always pushing out with nuclear energy and trying to crush in with gravity.
• and this delicate gravity nuclear balance is how stars stays alive.
• but eventually like a car running out of  gas, the star runs out of atoms to fuse but there is nothing to stop the gravity.
• As  a result everything that the star is made of comes crushing into the core.
• and all of this matter stuffed into a small place becomes a nuclear time-bomb.
• all of the matter and radiation blast out into the universe in a catastrophic explosion known as a SUPERNOVA.

Did you know that every single element we know was originally by exploding stars
