Radio signals from space : Are aliens trying to talk to us?

Radio signals from space : Are aliens trying to talk to us?

For the second time, scientists have been able to pick a freakish radio signal.

Known as "fast radio bursts", (FRBs) the repeating nature of the waves makes it possible to track its source, if only for a brief moment.

Constructed in British Columbia, CHIME is composed of four, 100-meter long half-pipe cylinders of metal mesh, which reconstruct images of the sky by processing the radio signals recorded by more than a thousand antennas.

In the latest one, there were a total of 13 bursts detecting in summer 2018, said the university's news release, saying the telescope wasn't running at full power.

Media from around the world are calling to ask about her team's out of this world discovery.

A SETI project snatched a few just this fall, but another effort using a brand new radio telescope called CHIME that essentially points at the whole sky and chooses where to "look" using software.

The novel radio telescope features no moving parts.

Some have suggested that these radio waves might not be natural, and could come from advanced alien races. "This is done using clever algorithms and a couple of giant computer clusters that sit beside the telescope and crunch away at the data in real time", Masui said in a statement.

Physics professor Max Tegmark pioneered these kinds of telescopes.

Of the FRBs observed to date, repeating bursts from a single source had been found only once before - a discovery made by the Arecibo radio telescope in Puerto Rico in 2015.

Loeb said we now know of two repeaters out of about 60 known sources, which "implies that the repeater population is not negligible but also represents a small minority, less than a tenth, of the entire population of FRB sources".

Most fast radio bursts pop up and disappear in short order.

Scientists have discovered mysterious repeating radio bursts coming from space for the first time since 2007.

Two researchers, combing the archives of the Parkes Observatory in Australia, found a radio signal the observatory recorded six years prior, but that nobody had noticed.

"Different emission mechanisms expect that FRBs will be emitted within a certain range of radio frequencies, much like a light bulb can not emit X-rays or a microwave oven can not emit ultraviolet light", Tendulkar told Gizmodo.

However, CHIME has now added 13 additional FRBs and a second repeater to the list.

For the second time in history, astronomers have detected a repeating fast radio burst (FRB) originating from outside the Milky Way. That suggests there might be even more of them, too low to be picked up by CHIME, reported The Independent.

The "scattering" phenomenon was detected in the radio bursts, which can help answer questions about the atmosphere surrounding the origin.

The amount of scattering observed by CHIME suggests these flares originate in powerful astrophysical objects, likely to be in locations with "special characteristics".
