Question

The collection, and study of details of known or unknown heavenly bodies in outer space is called………

Answer 1

Hint: We are always wandering about strange things happening in the night sky. So humans began a systematic study of the night sky and heavenly bodies such as stars, planets, shooting stars, etc. As we use the word ‘Biology’ for ‘the science of living things’, we use the word ‘Astronomy’ for ‘the science of stars’.

Complete step-by-step answer:
Astronomy is the branch of science that deals with the study of the sun, moon, stars, planets, comets, gas, galaxies, gas, dust, and other non-Earthly heavenly bodies and phenomena. Historically astronomy has been a popular science focused on the observations in the night
sky. You might have heard many bedtime stories about the constellations, zodiac signs, pole star, etc from your grandparents. These are the stories made by our ancestors to remember the position of a particular star or group of stars and their appearance over the year. From the position of stars, they used to predict the season of the year and do their agricultural works. In many religions and cultures, astronomy has a vital role to play. In Indian culture, we follow a lunar calendar which is dependent on the position and phases of the Moon.
Modern astronomy has mainly been divided into two classes: Observational astronomy and Theoretical astronomy. Astrophysics is a twin brother of astronomy.
There are many subfields of astronomy according to specializations of various astronomers such as cosmology, planetary astronomy, solar astronomy, etc.
Therefore, Astronomy is the collection, and study of details of known or unknown heavenly bodies in outer space.

Note: Astronomers might analyze the nightly positions of objects in the sky and regularities in their motion or they might find a similarity in the chemical composition of stars in different parts of the galaxy. They propose a hypothesis for the explanation for the result of the analysis and if the prediction of the hypothesis is found out to be true then it is assumed to be a correct explanation. For example, Newton proposed the law of gravity by observing many natural phenomena like tides, motion of the moon, falling objects on earth, etc. The discovery of Neptune and Uranus gives the strong verification of Newton's law since they were predicted based on this law.
