NASA's Spitzer Space Telescope has detected light from a super-Earth outside our solar system for the first time. Called 55 Cancri e, the planet is about twice as big and eight times as massive as our home world, and orbits its star, 55 Cancri, in a speedy 18 hours, a tad faster than our 365 days and change.
It, too, is uninhabitable, but for reasons that have nothing to do with bought and paid-for Washington politicians.
