Astronomers Have Discovered The Best Evidence Yet For a Rare "Missing Link" Black Hole – Astronomers have spotted what they think is a super-rare cosmic phenomenon: a type of medium-weight black hole proven so elusive that researchers thought it might not exist at all.

Diamond dust shimmering around distant stars – Some of the tiniest diamonds in the universe -- bits of crystalline carbon hundreds of thousands of times smaller than a grain of sand -- have been detected swirling around three infant star systems in the Milky Way. These microscopic gemstones are neither rare nor precious; they are, however, exciting for astronomers who identified them as the source of a mysterious cosmic microwave 'glow' emanating from several protoplanetary disks in our galaxy.

We're closer than ever before to producing clean water from thin air – Scientists from the University of California, Berkeley have developed a device that can harvest fresh water from dry desert air using only sunlight. While it's just a prototype, the scientists think production could be scaled up quickly.

The Atmosphere of Venus Is So Thick It Pushes On Mountains to Change How Fast the Planet Spins – Venus’ varying rotational period has always been a mystery for astronomers, but computer simulations show that it may have to do with the planet’s viscous atmosphere on mountains.
