No, really, they do. By radio waves!

Even more radio waves from space picked up by radio telescopes, with bonus astronomer snark from Jodrell Bank. Mostly it sounds rather more like early period Doctor Who watched on a badly tuned telly than anything that the Greeks imagined to be the music of the spheres, but it has its own beauty. I particularly like the "Jovian chorus". Jupiter, it turns out, twitters - like a bloodless dawn chorus, with added bat detector.

And talking of badly tuned tellies: a percentage of the 'interference' noise you get between stations is really, truly produced by radio waves which were emitted by the Big Bang. The whole thing is really quite awe-inspiring.

Stunning image of a dust cloud around Fomalhaut (Alpha Piscis Austrini). And yes, New Scientist are right, it does look like the Eye.

A friend of mine works on dust clouds. I wonder if I should be worried about what looks back at him?
