'Alien' signal turns out to be microwave oven

Astronomers in Australia discovered an unexpected source for a series of mysterious radio signals.
The team at the Parkes Observatory in New South Wales had been investigating unexplained radio signals known as a perytons which bear a close resemblance to the mysterious "fast radio bursts" recently put forward as possible evidence of a type of intelligent extraterrestrial communication.

Far from being a message from aliens however the perytons turned out to have a far more mundane, though amusing, explanation.
"We have identified strong out-of-band emission at 2.3-2.5 GHz associated with several peryton events," wrote astronomer Emily Petroff in a paper detailing the findings.

"Subsequent tests revealed that a peryton can be generated at 1.4 GHz when a microwave oven door is opened prematurely and the telescope is at an appropriate relative angle."

In other words - the mysterious peryton signals were being produced whenever someone was opening their microwave door before the timer had finished counting down.

Both Sweet P. its a Foodie Tech, make you hungry and sit down to think about it for a Nano Sec Thread ! Ok Im done ! Nope Still hungry !you knows me`s

Here is an article that challenges this: Mysterious Radio Bursts Are Indeed Coming From A Galaxy Far, Far Away New research clears the reputation of these distant signals Read article here: http://www.popsci.com/cosmic-whodunnit-culprit-ismicrowave-ovens

When I first got on the net, I got into an argument with a woman who could hear a local radio ham on her baby monitor. She was utterly irate, and got even more irate when I told he that it was probably the fault of her cheap monitor, not the radio ham. Hot Pockets were briefly sold in Australia, but not any more. LOL no. HAM operators are are only allowed to operate within specific bands and power. If they adhere to the rules they shouldn't interfere with household electronics. Many operators do not operate within these parameters however, and like to boost their equipment to get more range. Y... [More]

well apparently they knew the direction the signal was coming from, which ruled out the microwaves, wasn't there a simulair signal a few years ago? remains unsolved?

Your neighbor had a legitimate beef I don't want to hijack this thread, but one of the constant complaints of the amateur and other radio operators in Australia were that there are virtually no standards in the Australian regulations requiring that consumer grade receiving equipment had anti-interference circuitry ...

Here is an article that challenges this: Read article here: http://www.popsci.co...microwave-ovens Nice effort, She-Ra, but the article doesn't challenge it. It actually reports it. This article is about a different sort of signal, an FRB (fast radio burst.) The signal that turned out to be the microwave was what is called a "peryton." Harte

As long as the aliens aren't heating up their coffee in our break room, I don't care. BUM BUM BUM BUM..... Tonight on ancient aliens we explore microwaves. Where did they come from why are they here? Is it really to heat up your left overs, or were they brought here by aliens with a more sinster plot? Follow us tonight as we misquote scientists and fake translitatons tonight at 9!!!

I don't want to hijack this thread, but one of the constant complaints of the amateur and other radio operators in Australia were that there are virtually no standards in the Australian regulations requiring that consumer grade receiving equipment had anti-interference circuitry other than the usual tuning circuitry. This may have changed since. In an issue of "Amateur Radio" published by the Wireless Institute of Australia in the 1980s, it was noted that in some imported TV sets the portions of the circuit board that in other markets had such circuitry, it was absent in Australia. Aside from ... [More]

Man, ever since i heard this story months ago, every time i walk up to my micowave oven at night, the X-files theme song starts playing in my head.

As long as it isn't playing anywhere else, you're good.
