I've really enjoyed watching some of JPL's von Karman lecture series on YouTube. I'd really like to have more good quality stuff to watch online about solar system exploration - "good quality" meaning probably lectures and even rather technical ones, but not the slick, graphics-heavy, ominous voiceover discovery-channel sort of stuff (and definitely not the endless PROOF OF ALIEN LIFE ON TITAN stuff that makes searching for the good stuff so difficult). Any recommendations?
I have approximately a $1,500 USD budget and want to buy a telescope. I am pretty sure I want a Cassegrain (SCT or Mak of some sort) for portability. And I am pretty sure I want a German Equatorial Mount (GEM) for ease of manually tracking objects and the potential of maybe one day exploring astrophotography. I had selected the Celestron VX 8" SCT as it seemed to give me everything I was looking for. Then I learned about Push-To as an alternative to GoTo and that has given me pause. [more inside]
I am in mid-coast Maine. In the East, there is what appears to be a very bright star, but it is flashing both blue and red, which I have not known any star to do. However, it has been stationary for many minutes. What is it?
I'm trying to think of hands-on things that both kids and adults might like doing with astronomy apart from stargazing. [more inside]
Do these photos taken on Saturday near Barry's Bay, Ontario show the northern lights? I checked with a compass and they were definitely in the northern part of the sky. To the naked eye, it just looked like vague brightness. Aside from rotation and cropping, these photos are straight from the camera, processed from RAW in Lightroom. [more inside]
Hi everyone, My younger sister is 12, very smart, and has expressed interest in becoming a scientist. She loves physics and astronomy, especially, but she may have some untapped interest in other scientific fields as well. [more inside]
I got accepted to two PhD programs in physics, one at Clemson University, and the other at Ohio University. I have one week to make my decision and I'm frankly terrified of making the wrong one. I don't really know how either school is seen in terms of what a degree from either one would mean for my future career. I know that neither is particularly well known or prestigious (at least I'd never heard of them before I applied). So, can anyone, especially anyone who knows the ins and outs of grad school, and particularly anyone who has attended either (or both!) help me make my decision? [more inside]
So I recently bought a T-mount (with a 2x Barlow) to attach my DSLR to my 6" Dobsonian reflector telescope. Whilst this gives me great images of the moon and I managed to capture a decent fuzzy picture of Jupiter, I know I'm going to have to upgrade my gear to start capturing deep sky objects...

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]

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]

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..

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]

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?
