Jade Iceberg, Antarctica. When seawater at depths of more than 1,200 feet freezes to the underside of massive ice shelves, it forms ‘marine ice.’ Enormous hunks of ice break off from the ice shelf, creating icebergs. When one of these icebergs overturns, its jade underside is revealed. The wondrous color of this ‘marine ice’ results from organic matter dissolved in the seawater at those great depths. Green icebergs are infrequently seen because their verdant bellies are underwater; it’s only when they flip over, a rare event, that their richly colored regions can be seen before they melt.

This composite NASA image of the spiral galaxy M81, located about 12 million light years away, includes X-ray data from the Chandra X-ray Observatory (blue), optical data from the Hubble Space Telescope (green), infrared data from the Spitzer Space Telescope (pink) and ultraviolet data from GALEX (purple). The inset shows a close-up of the Chandra image. At the center of M81 is a supermassive black hole that is about 70 million times more massive than the Sun.
