Detailed explanation-1: -By studying the cosmos beyond our own planet, we can understand where we came from, where we are going, and how physics works under conditions which are impossible to recreate on Earth. In astronomy, the Universe is our laboratory!
Detailed explanation-2: -Science is an activity that attempts to enable us to get closer to true beliefs about the world. Its method is to begin with observation of the world and the formation of hypotheses (possible explanations for why things are the way they are).
Detailed explanation-3: -All known elements emit and absorb particular wavelengths of light, which is part of the electromagnetic spectrum. By studying the wavelengths of light (as indicated by ‘lines’ within the electromagnetic spectrum) emitted by an object in space, astronomers can get a range of information.
Detailed explanation-4: -Though scientific inquiry has been going on for a long time, thanks to modern technology, our knowledge has been expanding rapidly. This is partly due to systematic observation of the universe on both a large and small scale with instruments like telescopes, microscopes, and particle accelerators.
