What Is Astronomy?
Thursday July 8, 2004
From our Basics series:
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.

i think you should give a broader definition for us to understand well..tnx!!
Perhaps you’d find more information if you went to the article that this blurb links to.
It would be nice if you could explain it better to us kids.

i do not know.
help me please.
thank you.
that is very nice for this website to help people on thier homework cause most people need it
Is that really what astrnomy means.
I like it that you gave three ways of explaing what astronomy is but i need one answer… one answer that explains what it is…not three different ones, and i’m still going to have to choose which one i want.. geeee, dude.. we’re still learning… I think, if you were to teach us something or help us with this, you should have a better answer… but i give you props.. thanks man!
you are not giving me what i want. what would happen without astronomy!!
Yeah this helps heaps with my home work thanks Mr Greene
