Turns out the mysterious signal from the "Microwave oven"

Since 1998, an astrophysicist working at the Parkes Observatory, Australia, baffled by a mysterious signal called peryton (jump to article).

Many people believe that the signal was coming from the sky, possibly of alien. Meanwhile, the astronomers more believe that the signal was coming from the Earth, but do not know where.

Emily Petroff, a graduate student from Swinburne University in a research paper entitled "Identifying the Source of Perytons at the Parkes Radio Telescope" managed to answer the riddle of the signal.

Instead of coming from outer space or even aliens, it turns out the signal comes from the microwave that commonly used by astronomers to heat food. How Petroff uncover the source of the signal? How did the signal from the microwave can be detected?

Radio telescope facilities in Australia are in a signal isolated area. A signal from a mobile phone, for example, automatically blocked. Earlier this year, Petroff install monitor interference on the telescope. Surprisingly, peryton increasingly being detected, three times a week.

The signal monitoring with a monitor that shows the peryton has a frequency of 1.4 gigahertz. In between each peryton, there are other signals with a frequency of 2.5 gigahertz.

"It makes us think. What produces 2.5 gigahertz signal?" Petroff said. "The answer for sure is the microwave." However, there are still a mystery. What about the peryton has a frequency of 1.4 gigahertz. Petroff also continue to investigate. Then she discovered that the signal with the frequency coming from the microwave still burning, but the door is opened.

Revealed, the signal was there from the habits of the users who open the door before the microwave finished work. That fact may sound silly. However, as reported by Vox.com, research has now been entered arXiv paper that remains useful.

Astronomers are now trying to solve another mysterious signal believed to be from outer space, called Fast Burst Radio (FRB). Disclosure of peryton because astronomers were able to make a more select signals are obtained. They will not be fooled by the signals coming from the Earth when detecting FRB. *** [EKA | FROM VARIOUS SOURCES | VOX]
