What is astronomy ?

Question

Please give a short answer .

Answer 1

Astronomy is the study of anything in space.. celestial bodies, planets, moons..

You can see them through a telescope, which makes far away things look close up

Answer 2

There are different definitions of Astronomy. Some define it as a branch of science dedicated to the study of the motions and natures of celestial bodies, like planets, stars, and galaxies. Others say it is the study of objects and matter outside the earth's atmosphere and of their physical and chemical properties. Still others would say it is the study of everything, because it's a study of the universe and everything is part of the universe. All three definitions are accurate, but however you define it, there are many fields within Astronomy.

Answer 3

Astronomy is the science of celestial objects (such as stars, planets, comets, and galaxies) and phenomena that originate outside the Earth's atmosphere (such as auroras and cosmic background radiation). It is concerned with the evolution, physics, chemistry, meteorology, and motion of celestial objects, as well as the formation and development of the universe. The word astronomy literally means "law of the stars" and is derived from the Greek αστρονομία, astronomia, from the words άστρον (astron, "stars") and νόμος (nomos, "law").

Astronomy is one of the oldest sciences. Astronomers of early civilizations performed methodical observations of the night sky, and astronomical artifacts have been found from much earlier periods. However, the invention of the telescope was required before astronomy was able to develop into a modern science.

Since the 20th century, the field of professional astronomy split into observational astronomy and theoretical astrophysics. Observational astronomy is concerned with acquiring data, which involves building and maintaining instruments, as well as processing the results. Theoretical astrophysics is focused upon ascertaining the observational implications of computer or analytic models. The two fields complement each other, with theoretical astrophysics seeking to explain the observational results. Astronomical observations can be used to test fundamental theories in physics, such as general relativity.

Historically, amateur astronomers have contributed to many important astronomical discoveries, and astronomy is one of the few sciences where amateurs can still play an active role, especially in the discovery and observation of transient phenomena.

Modern astronomy is not to be confused with astrology, the belief system that claims that human affairs are correlated with the positions of celestial objects. Although the two fields share a common origin, most thinkers in both fields believe they are now distinct

Answer 5

The scientific study of sun , moon , stars etc.., Many findings have been made in astronomy by scientists .

Answer 6

Astronomy is the science of celestial objects (such as stars, planets, comets, and galaxies) and phenomena that originate outside the Earth's atmosphere (such as auroras and cosmic background radiation).

Answer 7

The study of EVERYTHING outside of the Earth's
atmosphere.

Clearly astronomy interfaces with many other disciplines,
including physics, chemistry, geology (though "geo" means
"Earth).

Answer 8

1.The scientific study of matter in outer space, especially the positions, dimensions, distribution, motion, composition, energy, and evolution of celestial bodies and phenomena.
2.A system of knowledge or beliefs about celestial phenomena: the various astronomies of ancient civilizations.

Answer 9

Oh, my God ! you have just pointed out to me how complicated a question can be in only three words. Basically, it is the study of stars and related objects in the heavens.

Answer 10

Study of the objects in the sky.
