What kinds of powerful telescopes did NASA have access to in the 1960's?

I'm curious as to what kind of powerful equipment NASA either had (or had access to) during the 1960's, which was considered among the best in the world for scanning the skies? And where were they located? [more inside]

Can the stars be seen more clearly when flying at 40,000 feet?

In relation to reading a recent article on the Skydeck, I wondered if flying at 40,000 feet and thereby removing an equivalent chunk of the Earth's atmosphere, made a significant difference in how clearly one can view the stars.

Books about physics (or related subjects) for middle school age girls?

I'm looking for books that either explain concepts in physics or encourage an interest in physics topics that are likely to be accessible and interesting for ~13 year old girls who are keen on science. What are the contemporary equivalents of "A Brief History of Time" and "Einstein's Dreams" for kids today? Related fields are welcome. [more inside]

Spaaaaaaace! Spacespacespace

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?

What telescope should I buy?

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]

What is that bright, hyper twinkling star-like object in the East now?

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?

Is this the aurora borealis?

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]

The Bobcat or the Tiger?

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]

Astrophotography 101

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...

I have no IDeaL what I'm doing (IDL programming for absolute dum-dums)

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]

Not my stats homework, I swear

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]

Blanket of Earth?

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!

Where should I put the prime meridian?

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]

Can you collect meteorite dust in your backyard? How?

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.

In my universe the dipper points to the South Star

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?
