How Do the Properties of Light Help Us to Study Supernovae and Their Remnants?
There are special properties of light that we can take advantage of to understand even objects that are millions and billions of light years away. In this section we explore some of these properties and how we can use them to understand our Universe. In the previous section of this unit, you were told that superheated material created by the supernova explosion gives off X-rays and gamma-rays. X-rays and gamma-rays are really just light (electromagnetic radiation) that has very high energy.
