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.

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?

Wanting to leave academia after astrophysics PhD (oscillations in atmospheres of rotating starts, planets and discs). Need some feedback, tags, hints, keywords, that I should search in google and some suggestions of where my skills (look in the extended explanation) would be appreciated.

There's this rather unspecific Feynman story that I keep encountering. Its formulation as found on the Internets goes
"One of the most impressive discoveries was the origin of the energy of the stars, that makes them continue to burn. One of the men who discovered this was out with his girl friend the night after he realized that nuclear reactions must be going on in the stars in order to make them shine.
She said "Look at how pretty the stars shine!"
He said, "Yes, and right now I am the only man in the world who knows why they shine."
She merely laughed at him. She was not impressed with being out with the only man who, at that moment, knew why stars shine. Well, it is sad to be alone, but that is the way it is in this world."
Does anyone know who he is talking about (Eddington? Perrin? Bethe?) and if there's any truth to the story?

I've heard astronomy has given us great insights about basic physics (and could be seen as a form of basic physics research). What technologies do we have today that can trace their gensis to astronomical findings?

AskMeFi Physics folk: How do astronomers account for the temporal distinctiveness of their galactic subjects in their calculations?
I understand that observations of the red shift of quasars delinates a speed increase in the expansion of the universe - yet my brain explodes when I try to understand how the enormous expanse of time
is factored into these models. [more inside]
