Venus, the closest planet to Earth in both size and proximity, remains a source of considerable mystery. Its reflective clouds prevent a clear view of the planet, and for centuries little was known about its surface and inner workings. But radar and gravity data acquired in the past few decades by spacecraft such as NASA's Magellan , which orbited Venus from 1990 to 1994, helped refine planetary scientists' understanding of Venus's past. The impact history recorded by the planet's craters indicated that Venus had been resurfaced by volcanic activity relatively recently, just a few hundred million years ago . [More]

On tiny keypads and greasy touch screens, doctors, nurses, NPs and physicians assistants these days are doing a lot more than checking email and phone messages.

That's why we burn it to make electricity.
