It includes the study of spaceships, planets, galaxies, stars, solar system, and all related things that present in the space. It also describes the life of space. It has further branched such as Astrophysics is an integral part of the astronomy. There is multiple regulation of physics scientists include in it. People got complete knowledge about the origins of universe and the objects in it due to astrophysics and astronomy. Whether it is layman astronomer or an experienced astronomer, both can devise the space related theories and applications for universe observation. It also helps us to understand what are planets, stars, and galaxies. There are different branches of Astronomy. But two of them are the major ones that are optical and other one is non-optical astronomy. The first one is about the usage of astronomical instruments for space objects study in the radio via gamma-ray wavelengths. The last one is there is a smooth wavelength that is infrared astronomy, gamma-ray astronomy, etc. Both branches are helpful and give accurate results on the ground and in the space. The prime example of this is, HST that refers to the sensitive instruments to other wavelength of light.
