NASA's space shuttle Endeavour lands before dawn on Monday morning at Kennedy Space Center in Florida.
Endeavour's six-astronaut crew delivered spare parts and a new dark matter detector to the International Space Station during the shuttle's latest 15-day mission—Endeavour's 25th and final flight. Next up for the orbiter: being cleaned, mothballed, and retired to the California Science Center in Los Angeles.

Green Crystal "Rain"
Green crystals may be pouring onto the infant star HOPS-68 (indicated by the arrow in the telescope image at top), according to NASA.
Detected in infrared pictures from the Spitzer Space Telescope, the crystals are thought to have been shot out in jets by the protostar at a young age (illustrated by an artist in the middle picture) and are now falling back like rain (illustrated at bottom).
