    A supernova is one of the strongest explosions in the universe and will even outshine a whole galaxy! The last time one has occured in our galaxy was Keplers Star in 1604. One of the most famous remnants of a supernova is the Crab Nebula from a star that exploded in 1054.

    When a sun has used all of its nuclear fuel at the core, a sun will generally die out. But, especially if they are very large stars, the core will collapse in on itself and thus create a massive explosion. These are very rare events and one that sparks new life and even creates a rapidly spinning neutron star from the explosion.
