First up, square Earth anyone? Forget realism, let's just have a think about what an Earthlike planet would be like if it were a cube. Puts me in mind of the planet builders in Hitchhikers' Guide to the Galaxy. Brought to you by Discovery News.

Second, the Planetary Habitability Laboratory talks about brightnesses of the various planets in the solar system and also of exoplanets. An interesting read, particularly if you enjoyed my old How Bright is the Night? post.

Enceladus pics from Cassini. Enceladus is one of Saturn's moons, most famous for it's ice geysers.

Proposed space robot to cannibalise old satellites which have previously been boosted up to "graveyard" orbits. Many mentions of zombie satellites and grave robbing associated with this one ;-p . From New Scientist.

And finally, laser driven fusion in California. From New Scientist again.

Happy weekend, gentle readers!
