• Forget OxiClean. The "power of diamonds" can help clean away tough stains in every laundry load. Nanodiamond particles in laundry detergents can dislodge dirt from fabrics without using hot water -- saving energy and adding some sparkle. [url]
• There's a recently de-classified deposit of impact diamonds in Russia -- and it's so big that it's estimated that this resource could serve the world's diamond needs for 3,000 years. These impact diamonds are twice as hard as traditional gemstones because they're formed when a carbon-rich meteor collides with the earth and the resulting explosion creates this unique material.

• Diamonds aren't as rare as most people think they are -- if you're willing (or able) to travel a few thousand light years, you can find a whole planet made of diamond. A carbon-rich planet that is probably crystalline (and hence diamond-like) orbits the pulsar J1719-1438, and it's the most dense planet seen so far. [url]

The Hubble is looking at a green gas cloud called Hanny’s Voorwerp. The object was discovered in 2007 by Dutch schoolteacher, Hanny van Arkel. [url]

The Kepler telescope found a solid planet about 40% bigger than Earth. That planet is more than a bit too hot for our biology, but there are at least a few hundred more planets in Kepler's sights. [url]

Mars might have giant caves! Or at least, it has big dark craters of some kind. [url]

Here's a "mysteries of space" timeline. Seriously not drawn to scale... especially a googol years in the future. [url]
