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.

Astronomy:
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.
Universe/Cosmos:
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:
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.
