Observational astronomy

Observational astronomy is a type of astronomy. One has to record, analyse, and study data taken from giant telescopes located in observatories in isolated places. People will use giant telescopes to take a look on an object in the night sky and then study that object. Many times, one will have to study a photo of an object they themselves did not take.
