What is the meaning of astronomy?

               Astronomy,space science and the astronomy permit us to see the universe and our place in it.Through considering these subjects, humanity has persistently broadened its points of view and investigated the cosmos.The subjects ceaselessly advance and change each year dependent on disclosures by investigates all around the world.Astronomy is one of the most seasoned sciences,practised by the vast majority of the world's antiquated developments a one of the most modern,relying for some ongoing revelations on hight innovation and space programme.It is an observational science that gives our perspective on the immense scopes of sizes of space,time and states of being in the universe.
What is the meaning of astronomy?

                     Astrophysics underlines the fundamental physical concepts,of the stars and galaxies,which create the universe,providing a comprehension of the physical idea of bodies and procedures in space and the instruments and methods utilized in current galactic research.The space is regularly alluded to as the last wilderness o investigation by mankind.The space investigation and perceptions depend to a huge stretch out on satellites and different types of room probes.The desisgner of space types of gear need a decent comprehension of material science and astrophysics,together with speciallised designing abilities.

Natural science which manages composition,motion and other extra highlights of the celestrial bodies is called astronomy.There are different parts of space science like Astrophyics(Astronmomy+physics),Astrodynamics,Astrobiology etc.The researcher relating to cosmology are called stargazers.

Our earth,space and each divine body like galaxy,sun,star,planet,comet etc.present ina framework are all in all called universe/universe while the investigation of these is called cosmology. Our universe is made of billion of worlds and each cosmic system has billion stars.These stars may have their own family like our Solar framework which has eight planets including earth as an individual from the family.

Prominent Astronomers and their Outstanding Contributions in a word

Ptolemy's Geocentric theory:
In 140 AD Ptolemy,a Greek astromer,studied about the universe and propounded the geocentric (Earth + driven) theory.According to this hypothesis the earth is restricted at the focal point of the universe,while the sun and different planets rotate around the earth.

Copernicu's Heliocentric Theory:
A Polish stargazer Copernicus propounded the heliocentric (Sun+ driven) hypothesis in1543 AD.According to this hypothesis the sun is limited at the focal point of the universe,while the earth and different planets rotate around the sun.Thus,Copernicus was the main space expert who propounded planetary movement around the sun.

Kepler'Laws of planetary motion:
J.Kepler (1571-1630) did thorough investigation of the heavenly bodies and their motion.He inferred that all the planets spin around the sun in different curved ways.

Galileo(1564-1642) who was a contemporary of kepler affirmed and upheld the philosophy and far reaching perspective on Kepler.The start of present day stargazing appeared in1609,when the refracting telescope was developed by Galileo.Galileo was the space expert who was found four satellites of the planet Jupiter and sun spots in the sun.Galileo additionally found the closest star of the sun Proxima Centuari.

Sir Issac Newton:
British physicist Newton (1642-1727) who designed reflecting telescope in1668 additionally contributed about the planetary movement based on the clarified gravitational power field theory.Later Newton's law of gravitation,which turned into the most key and essential laws,was saw as equal to Kepler's laws.
