New Scientist wins the best article title this week with their effort: Do gravity holes harbour planetary assassins?

It’s about Lagrangian points, or fixed gravity-neutral points in space:

They are the places gravity forgot. Vast regions of space, millions of kilometres across, in which celestial forces conspire to cancel out gravity and so trap anything that falls into them. They sit in the Earth’s orbit, one marching ahead of our planet, the other trailing along behind. Astronomers call them Lagrangian points, or L4 and L5 for short. The best way to think of them, though, is as celestial flypaper.

Wikipedia also has a tops article explaining the five points relating to earth with some neat diagrams. Ooeer, that’s about enough Sunday morning science, I think.
