And so, the microwave oven is briefly transmitting radio waves into the open. Why is the impatience over a warming Hot Pocket important? If you open the microwave door before the timer goes off, the thing in the oven that produces microwaves – it’s called a magnetron – hasn’t had a chance to completely shut off. When Petroff and her colleagues tested their hypothesis, they found they could create perytons on demand simply by opening the oven door before the timer had dinged. The team recognized the interloping frequencies as possibly belonging to a microwave oven. In January, the telescope detected three of the signals – and the interference monitor picked up three simultaneous interference signatures. Petroff and her colleagues discovered the source of perytons after they installed a real-time radio interference monitor at the Parkes telescope. Just how close to Earth was a mystery until now. Astronomers knew that perytons were locally grown because the signals simultaneously showed up in multiple viewing fields rather than arriving from a single point, as distant signals do. There have been dozens of reported perytons, some dating back to the 1990s, and theories about the signals’ origin included ball lightning, aircraft, and components of the telescopes themselves.īut almost since the beginning, one thing has been clear about perytons: Despite mimicking a deep space signal, they’re produced by something that’s somewhere near Earth. “It was quite surprising that it ended up being microwaves,” says study author Emily Petroff of Australia’s Swinburne University of Technology.įor years, astronomers had been puzzled by these brief but intense bursts of radio waves that in some ways appeared to be coming from deep space. Well, the collection of formerly mysterious radio signals: A study posted to the arXiv on April 9 identified microwave ovens at the Parkes site as the rather mundane source of perytons. If you happen to be reheating your coffee at the Parkes Observatory in Australia, you could be contributing to the growing collection of mysterious radio signals known as perytons. You may have just unleashed a small but mighty radio signal that could be detected by a nearby, sensitive radio telescope. But it becomes especially unwise if you’re using a microwave oven near a radio telescope and you’re so eager for that icky, burnt and wholly unsatisfying taste that you prematurely pop the coffee out before the oven’s timer goes off. Let’s be clear about one thing: Reheating coffee in the microwave is always a poor life choice. ![]()
