Aerogel, also know as frozen smoke, is the world’s lowest density solid, clocking in at 96% air. If you hold a small piece in your hand, it’s practically impossible to either see or feel, but if you poke it, it’s like styrofoam. It supports up to 4,000 times its own weight and can withstand a direct blast from two pounds of dynamite. It’s also the best insulator in existence.

The “Black Widow” pulsar is moving through the galaxy at a speed of almost a million kilometers per hour, a bow shockwave due to this motion is visible to optical telescopes, shown in this image as the greenish crescent shape. The pressure behind the bow shockwave creates a second shockwave that sweeps the cloud of high-energy particles back from the pulsar to form a cocoon

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
