Looking for general and specific recommendations for outer space and astronomy themed merchandise, collectible, and other vendors, for a maker / science fair being held in the Los Angeles area. For example, a local comic book/toy shop that has vintage Space 1999 and Star Trek collectibles, a hobby store that specializes in Estes and other rocket sets, or even maybe some random dude looking to sell of his collection of used spacesuits.

Tricky query to formulate so bear with me... I'm curious to what extent that astrophotography images represent the form of their subject matter, and whether the chorus to this song could ever actually happen. More inside.... [more inside]
Help me think of a space-themed gift for an awesome 35-year-old guy. [more inside]
What were the best photos we had of the planets in our solar system before the Pioneer and Voyager missions? [more inside]
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. Details: [more inside]
An NPR blog cites an NSF study which claims that 26 percent of Americans asked answered that the Sun goes around the Earth, rather than vice versa. Believing that 1 in 4 of my fellow citizens doesn't know that the Earth circles the Sun is hard enough. But thinking about that number, it seems worse than that: if 26% got a 50/50 question wrong, wouldn't another 26% have answered correctly just based on chance rather than knowledge? That would mean that roughly half of Americans didn't know (and then split evenly on their guess). The idea that half of Americans don't know seems intuitively ludicrous to me. Am I missing something in how I think about this? Please help my statistically challenged brain... [more inside]
I want to build a solar system with a decent amount of verisimilitude, and the math and physics are killing me. [more inside]
Tonight my 8 year old niece told me that for Christmas she wants a blanket for her bed that has a giant picture of Earth on it. I asked her if she saw this somewhere, and she told me that she just thought about how cool it would be in her own head. I tried doing a Google search, but I'm having no luck. Anyone have an idea of where I might find such a thing? Thanks!
So I've just sent a probe to map a new Earth-like planet, and I'd like to establish a latitude-longitude standard for the planet. The poles are pretty easy to spot since the planet is rotating, so I plop down the equator halfway between them and boom, I've got my latitude lines laid out. But now it's time to lay out the longitude lines and I need to find somewhere to put the prime meridian. How do I decide where to put it? [more inside]

It is an antiquarian image, showing a person peeking out of a globe into the stars or something. I'm pretty sure it has something to do with metaphysics. I swear it is on the tip of my tongue..

Since we're in a period of increasing solar activity, I'm hoping for some hot aurora action in the NY Tristate area. But while there are countless aurora forecast/advisory services, I can't find one for this area. [more inside]

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]
How can I find out which semester has the the largest number of clear nights? I'm teaching an observational astronomy class this term and am getting frustrated by the number of cloudy nights. Is this just life in New England, or would teaching it in the Spring be better? [more inside]

When you look up on a starry night, you see more than a thousand points of light. How many of what we see with the naked eye are stars and how many are galaxies?
How many of the stars whose light we see at night are actually already dead/gone/disintegrated? [more inside]
Batshit insane filter: I recommended to a friend, 1Q84, the best book I've ever read. He loved it. I had lunch with him this week and he said he thought he was in an alternative himself, as one night he looked up at the Big Dipper and it appeared to be backwards, pointing toward the south. Yikes, I had the same experience myself recently. Whats going on here? Is it an astronomy thing or will Tengo and Aomame appear soon?

I'm working on going back to school for Astronomy/Astrophysics, but I need help figuring out what classes to take at the Community College level here in San Francisco and how best to apply to a school like UC Berkeley. Complicating matters is the fact that I went to school for 4 years for film (don't ask) at Drexel University but didn't graduate. Luckily I spent my first two years at Drexel on a general science track. What I really need help with is figuring out what classes I should take at a school like City College of San Francisco. Also, when is the soonest I can/should apply to UCB? Alternately, what San Francisco adjacent schools have really good astronomy/astrophysics programs? [more inside]
