Cosmos has me very intrigued. Assume I know less than a 5th grader. I am looking for: book recommendations for basic astronomy concepts; blogs; podcasts for beginners; good audio books; and documentaries. If you wanted to teach an adult about astronomy where would you start?

So, I recently got selected to do undergraduate physics research this summer. Great! Awesome! Yay me!
However, my research advisor has asked me to use something called IDL to analyze tomographic images of compounds and turn them into 3D images. This is good news, because IDL is used a lot by astronomers to analyze astronomical data, and I want to continue my education in astronomy. But, I've never used IDL ever before. I'm not even sure exactly what it is (a programming language?).
My question is this: how do I get up to speed so that I can hit the ground running with my research?
Difficulty: Research begins in two weeks.

I've been told recently that collecting micrometeorites is as easy, basically, as placing a clean surface outside and picking through the debris you collect because thousands of tons of space dust and debris fall to Earth every day. That can't be all there is to it, can it? How do you know whether you're looking at Earth dust or space dust? [more inside]

If I've gotten the right impression, much of our currently visible universe will eventually be expanded away from us, never to be seen again. Do we already know how much and what parts of our present neighborhood we'll be left huddling with?

I've been rewatching Carl Sagan's Cosmos since I found out it's available on Hulu. Last night, I was watching the episode in which Carl describes how the solar system was formed via the coalescence of particulate matter. But, something struck me as rather odd: if hydrogen and helium are lighter than the heavy elements (duh!) why is it that THEY coalesced into the center of the solar system to become the Sun? It seems to me the heavier elements would migrate towards the center of the maelstrom a bit faster than the lighter ones.
Haven't been able to find out the reason for this, hoping the hive can help.

In my view of the sky from Mobile, AL - looking southward - there is a star shimmering brightly in red, yellow and even green. What is it? [more inside]
