High-energy astronomy

space Maturity 9-11 Next article →

Some things in space are very strong. They send out light with a lot of power. Scientists study these things. This is called high-energy astronomy. It is the study of light with very short waves.

Scientists look at many different objects. They look at black holes. They look at neutron stars. They also look at stars that explode. We call these explosions supernovae.

Some objects are called active galactic nuclei. These are very bright parts of galaxies. Some things send out tiny bits called neutrinos. Others send out cosmic rays.

We use special tools to see these things. Some tools are called telescopes. Some stay on the ground. Other telescopes fly in space. Many missions help us learn. Some names of these missions are Chandra and Swift. Another is NuSTAR. We also use a tool called IceCube. These tools help us see the most powerful parts of space.
