READING 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 ofthe 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! Task 1.
