2^nd International Conference On Astronomy, Astrophysics & Astrobiology

Astronomy

Natural Science is a branch of Science which explains the natural phenomena with description, prediction, and understanding based on observational and empirical evidences. Astronomy is the Oldest of natural sciences and an effort to explain the origin of various objects and their evolution. According to NASA (National Aeronautics and Space Administration) Astronomy is the study of “stars, planets and space”. It is a growing field in research and development and almost every day a new discovery is being made. Various questions like – How did galaxy formed? How was sun created? How long does it take to travel from one planet to another? How many solar systems are there in this universe? What is Higgs Boson? How Did the First Quasars Form? And so on….. Finally have answers, thanks to astronomy.

The early civilizations in history such as Greeks, Egyptians, Nubians, Iranians, Chinese, and Indians performed methodical observations of the night sky to make calendars. So, in 20^th century the field of professional astronomy was split into two branches

 OBSERVATIONAL Astronomy and THEORETICAL Astronomy.

Observational Astronomy, the data is acquired from observations of astronomical objects which are then later analyzed via basic principles of physics.

Theoretical Astronomy on the other hand bends towards computational or analytical models to explain an astronomical objects as well as phenomena.

Both the fields are related to each other as theoretical astronomy explains observational results and vice versa.
