Last week it was announced that a large asteroid would be passing close by Earth on Oct. 31 – Halloween. It has already passed as I write this and nothing extraordinary happened, except that a very spooky image of the asteroid was captured by bouncing radar pulses off it.

As Phil Plait (famed “Bad Astronomy” blogger) explains, this isn’t really a photograph, but a 2 dimensional plot of certain characteristics of the radar signal. Nevertheless, that this would happen on Halloween seems a little too coincidental!
