Since 1998, astrophysicists at Australia's Parkes Observatory have been detecting mysterious bursts of radio waves (named "perytons") that seemed to emanate from all parts of the sky. They lasted for just fractions of a second and happened once or twice a year.

Most believed they came from somewhere quite nearby (perhaps resulting from lightning strikes), but the bursts had some characteristics that made it seem like they'd traveled millions of light-years from distant galaxies or other astronomical objects.

The truth, as recently discovered by graduate student Emily Petroff of Swinburne University of Technology, is decidedly more mundane. It turns out the signals were generated by someone at the facility opening the door of a microwave oven while it was still running.
