how is light used to study space?

Question

anonymous · Answer

In the broadest sense possible, light is used to study space because astronomy is an observational science. So to learn about objects we study the light that we receive from them. This may be from any part of the EM spectrum. Some objects, such as pulsars emit radio waves which are long wavelength EM waves. Others such as Gamma-Ray Bursts, emit Gamma Rays which are extremely short wavelength. Stars obviously emit a lot in the visual spectrum.

To study space we have to study objects in numerous different spectral regions. It may be the case that a particularly visually dim star may be emitting huge amounts of X-Ray energy. That's why we use satellites and telescopes that detect different types of light.

Hope this sets you on your way

ok, that helps a lot. If I were to type an answer, I'm not sure what I would say though. obviously i don't want to use exactly what you said and that answer may be a little to long.
