Why Is NASA Studying Gamma Rays?
Gamma rays are mysterious. They have so much energy that they are hard to find. Special instruments have to be built to study them. NASA studies them to learn more about the universe. Gamma rays help NASA learn about the places they come from. NASA can learn more about black holes and exploding stars by studying gamma rays. How Does Fermi Work? The Fermi telescope has two main tools. It has a large telescope that finds gamma rays. It also has a tool that looks at quick bursts of gamma rays. Most of the places where gamma rays are made are a mystery. Scientists do not know what causes gamma rays to form. Scientists hope Fermi will help them solve that mystery.
