Supernova
By:Jamie Kim
What is a Supernova?
A supernova (supernovae) is when a star build up so much energy that they explode
Location
Since stars are spread out all around the galaxy there isn't a specific location for supernovas.The last visible supernova in the milky way was seen by Johannes Kelper.
Cassiopeia A
This one is the youngest star remnants in the Milky Way.
Crab Nebula
This is one of the most famous supernovas ever because it exploded in a different way.
Physical Properties
There are so many elements thats star's can be made of that there isn't just one I can name.The most common one is iron.When they explode their light can be a billion times the sun.Also,when they explode they send elements and other things shooting everywhere and that can help form new stars.
Movement
The first type of supernovas are called the Binary Star system.This is when two stars orbit the same point.The first star is called the dwarf str and it just steals matter from the other star to get bigger.Then it holds too much matter that it explodes!
Movement (continued)
The second type is what happens at the end of a star's life.Mass from the outside then flows to the core.The core can't hold up all the mass and explodes!It can end up as a neutral star, a wormhole,and a black hole.
History
Every star is unique in their own way.There isn't just one specific history for all of them.The last visible supernova in the milky was discovered by Johannes Kelper.
