NASA's Threesome

Prepare to be astounded: the image on the right is in . . . three dimensions

Seven months after its launch, NASA's STEREO satellite has sent back 3-D images of the sun. The Solar TErrestrial RElations Observatory (guess STRO wasn't a cool enough acronym) charts the flow of matter and energy between Earth and the sun, and maps out things like solar storms and coronal mass ejections--actually useful for us, since these storms and CMEs will be used to better predict the next blackout-inducing maelstrom.

So what's NASA been up to while its probe undertakes a two-year photo shoot? Well, it's been typing up the instructions on
how to make your own 3-D glasses. (Hint: it's exactly what you'd imagine.) —Abby Seiff
