Paging Al Gore

Signs of, well, something on another planet:

NASA’s Hubble Space Telescope has discovered carbon dioxide in the atmosphere of a planet orbiting another star. This breakthrough is an important step toward finding chemical biotracers of extraterrestrial life.

The Jupiter-sized planet, called HD 189733b, is too hot for life.

You just know the greentards are going to find a way to pin this one on us.
