is astronomy part of physics?

Question

iyuko · Answer

It's not apart of math.

michele_laino · Answer

yes! Since when I was at my university, there was an exam entitled "Astronomy"

bmxlifestyle · Answer

but physics is the branch of science concerned with the nature and properties of matter and energy. The subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms and astronomy is the branch of science that deals with celestial objects, space, and the physical universe as a whole. @Michele_Laino

michele_laino · Answer

yes! Nevertheless in order to study those celestial objects, we need of concepts like gravitation, field of force, and  angular momentum, for example

bmxlifestyle · Answer

oh ok makes sence

michele_laino · Answer

and those concepts belong to classical physics, and to the General Theory of Relativity developed by Albert Einstein

anonymous · Answer

Yes. It's actually the most advanced science that you can apply physics to since it encompases almost every branch of physics. To outline a few of them:

- relativistic mechanics, which will also "force" you to go through newtonian mechanics as well 
- special and general relativity 
- thermodynamics (energy and heat transfer within celestial bodies)
- electromagnetism (since you'll be studying all kinds of radiation coming from outer space)
- optics, waves and oscillations (besides knowing about the instruments that you are using, it's also very hard to understand the  behaviour of light without knowing a thing or too about the wave characteristics of it)
- quantum physics (if you intend on going in depth with nuclear fussion that happens at the core of stars or the nuclear fission that causes bursts of radiation or go so far as to study the Big Bang and all that) 

and so forth.

im so confused haha

anonymous · Answer

There are very few parts of physics that I cannot find a direct application or connection somewhere with astronomy.

anonymous · Answer

Well, the point is - it is. I don't see why those two definitions are in contradition with each other. Is the Universe not made of matter, energy, waves, radiation, magnetism and so forth ?
