Well – invisible stuff IN space. Effusions of gamma rays, clouds of X-rays, "filaments, clouds, shells", all known technically, if I recall, as space gush. Columbia Hubble Fellow Joshua Peek (almost certainly not the same guy as the rodeo Josh Peek) gets to look at these wonders through big telescopes. He collaborated with Sony Ericsson's Xperia Studio to make an Android app, The Invisible Universe, so the rest of us could look at them with phones.

I don't own an Android device, but now wish I did. No matter: this video about the project, a masterpiece of product understatement, leaves the app almost unmentioned as it chooses instead to simply Make Cool of Peek's work. It nicely humanizes Peek, who seems hip and fun and smart, and the earthy attention paid to his office and lab — notebooks, drawings, lenses, stacked astrophysics journals — anchors us and the film. It's gorgeous.
