Go to the October 3th 2007 entry and look very carefully at that grainy, weird, animated black and white picture.
That's a comet. Viewed by the Icarus satellite. Watch what happens.
(Edit: change 13th to 3th. Yes, I do mean 3th not 3rd, because I like to poke at words with sharp sticks sometimes to see if they'll bite me. No idea why my brain added 10 there.)
