Now if you could get that in a single frame, it would be worth getting up for. The hype over meteor showers makes me cringe. 100 an hour? Count slowly: "1,2,3....30 Whee! 1,2,3....Ooh!" Anything under 1000 an hour should be described as "weak." What's the harm? Well, look at all...

The Moon is lit, but the albedo (reflectivity) of the rocks on the Moon is very low - almost black. No, this is for real.

Re: APOD: Stereo Pluto (2015 Aug 06)

If Pluto were in our own Moon's orbit around Earth (instead of the Moon we have) it would appear only 0.7 the size we do see for our own Moon.

sorry, I meant to say, cross your eyes on the henrystar version and Pluto will appear in 3D correctly: http://henry.pha.jhu.edu/correct

So, how does it work? I've been staring at this image for ¼ hour and don't see anything special. How do you "merge" these images? Do I need one of those old victorian stereopticon devices? I feel very left out. Just cross your eyes, so that the two images merge. Pluto will pop out, and st...

Ho ho ho! I crossed my eyes - and I saw a hollow sphere, with the surface of Pluto on the inside of the sphere! What fun! Then, of course, I took screen shots of the two images, put them side by side, just as they were in APOD, and verified that I got the same weird effect. Then I switched them, le...

Love to see the name "Circinus X-1" When I joined Herb Friedman's group of X-ray astronomers in 1967 there was great rivalry with Riccardo. Herb called his X-Ray sources "X-n" and Riccardo called his "XR-n". The race was won by Riccardo, and Herb didn't live long enough...
