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.

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.
