Mysterious radio signal found in space and astronomers aren’t sure where it’s coming from


USA Today reports that in 1998 a radio signal found in space was later found to have originated from a microwave.

For all the info. Original media available.

A mysterious fast radio burst (FRB) that hit Earth late last month has been detected. While this type of activity is by no means common, it is not unusual.

The part that’s puzzling scientists is not the radio burst itself, but the fact that its frequency is nearly 200 megahertz lower than any other radio burst ever detected.

Mysterious radio signal from space? Astronomers aren’t sure of origins

A mysterious, low-frequency radio signal was detected using a radio telescope based in Canada, astronomers say. The source of the signal is not clear.

Moving on.

A mysterious radio signal has been spotted by a telescope in Canada, and it’s one of the lowest in frequency to date.

Details of the signal were posted to The Astronomer’s Telegram, a website where accredited astronomers can post observations.

Microwave oven to blame for mystery signal that left astronomers stumped

The mystery behind radio signals that have baffled scientists at Australia’s most famous radio telescope for 17 years has finally been solved.

The signals’ source? A microwave oven in the kitchen at the Parkes observatory used by staff members to heat up their lunch.

Simon Johnston, head of astrophysics at the CSIRO, the national science agency, said astronomers first detected the signals, called perytons, in 1998. The signals ‘were reasonably local, say within 5km of the telescope’.

Then on 1 January this year they installed a new receiver which monitored interference, and detected strong signals at 2.4 GHz, the signature of a microwave oven.

Juno’s new Jupiter

In ancient Roman mythology, Jupiter, the king of the gods, had the ability to hide behind a veil of clouds. Only his wife, Juno, could see through. Today another Juno is peering through Jupiter’s veil: the NASA spacecraft, launched in 2011, has been orbiting the planet since 2016.

In the last year, JunoCam, mounted on Juno as an afterthought, has wowed earthlings with breathtaking close ups of swirling Jovian cloud formations such as the Great Red Spot and the wondrously filigreed patterns at the edges of Jupiter’s multi-coloured atmospheric bands.
