What are the basics of Astronomy?

Question

Also "What are auroras"?

Answer 1

The universe is huge but dumb and we are tiny but smart (in some ways) - but neither of us is infinitely large nor will either of us last forever. There are both scientific and humanistic lessons in this hard-won knowledge.

Auroras are the effect of charged particles from the sun being captured by the earth's magnetic field in the upper atmosphere, where they are absorbed and re-emitted in visible wavelengths.

Answer 2

The basics of astronomy are stellar evolution and astrophysics. The underlying concept, foundation, or "unifying" concept in astronomy is the big bang theory.

You have plenty of good responses on auroras already.

Answer 3

If you really want to be taught basics of astronomy I have an astronomer friend who can really teach you everything you need to know plus he'll get you set up with the propper telescope and help you observing.
Also he'll not only teach you what an aurora is he'll teach you how to observe them.
You'll be glad you emailed him.

He's a pro at teaching that, no kidding either

Answer 4

Auroras are gases glowing near the poles which are struck by energetic particles guided there by the earths's magnetic field. For your first question pick up a beginners book on astronomy and enjoy it.

Answer 5

There are a lot of basics in astronomy - basic planetary science, basic stellar physics, basic solar physics, basic atmospheric physics, basic galactic astronomy, basic cosmology. You might be better off getting an intro textbook.

Auroras are solar wind from the sun interacting with particles in our atmosphere, emitting light as they spiral along the magnetic field lines of the Earth.

Answer 6

Auroras are causes when highly charged plasma bursts from the Sun interact with Earth's upper atmosphere.
