Search for Supernova

Sometimes a star explodes. The explosion is called a supernova.
Supernovas are the biggest explosions that happen in space. They are one of
the most powerful events in the universe. Usually, changes to planets and stars
happen very, very slowly. For example, it took millions of years for our solar
system to form. That is a very long time. A supernova, however, happens very
quickly. The explosion lasts only about 15 seconds.
In Galaxies Far, Far Away
A galaxy is a system of millions of stars and the planets that circle them. Our solar system is
in the Milky Way galaxy. In galaxies like ours, there are two or three supernovas every hundred
years. There are many, many galaxies in the universe. Scientists can usually observe a few hundred
supernovas every year.
Ingredients for Planets
Supernovas are important for shooting elements into the universe. Everything in the Universe
is made of matter, and matter is made of elements. Huge stars are kind of like factories. The burning core of a star cooks up the elements needed to make everything else in the universe. When a star
explodes, it shoots the elements into space. Eventually, the elements form new stars and new
planets. These become solar systems, which make up galaxies. The elements are ingredients for
making planets, moons, and even us!
