Tenth planet found!
A team of astronomers systematically scanning the far reaches of the solar system has discovered a distant, icy world that is bigger than Pluto but so far away the head of a pin held at arm's length would blot out the sun. The discovery, if confirmed, would force astronomers to re-write their textbooks and give school kids a 10th planet to memorize once a governing body sanctions the still-secret name proposed by a trio of discoverers.

Timing of foam loss saved Discovery from big hit
The shuttle Discovery's crew might have dodged a bullet when a piece of foam debris broke away from an aerodynamic ramp on the side of the ship's external fuel tank during launch Tuesday. Had the foam broken away earlier, when the shuttle was deeper in Earth's atmosphere, the chunk could have hit the orbiter with potentially catastrophic results, engineers said Thursday.
