15 mysterious radio emissions detected in alien life probe

Distant galaxy sends out 15 high-energy radio bursts

This most recent event came courtesy of one of the usual suspects, FRB 121102, which has been heard on and off for years.

The initiative is backed by Mark Zuckerberg, Stephen Hawking, and billionaire Yuri Milner and has been gathering information with the Green Bank Radio Telescope in West Virginia, Lick Observatory's Automated Planet Finder on Mt Hamilton in California, and the Parkes Radio Telescope in Australia, points out DailyMail. FRBs are brief, bright pulses of radio emission that originate from distant galaxies.

While we know the general location of FRB 121102 - a dwarf galaxy about 3 billion light years away - we don't quite know yet what generates these sounds.

"The extraordinary capabilities of the backend receiver, which is able to record several gigahertz of bandwidth at a time, split into billions of individual channels, enable a new view of the frequency spectrum of FRBs, and should shed additional light on the processes giving rise to FRB emission", says Vishal Gajjar, a researcher on the Breakthrough Listen project.

The source known as FRB 121101 was discovered back on November 2, 2012, by astronomers using the Arecibo radio telescope. "The new data are likely to be helpful in figuring out what's going on here, but of course it could be that this particular object is a member of an "FRB subspecies" - and not typical of most of these weird cosmic screamers", he says. This is the first time bursts from this source have been seen at these frequencies. After observing for five hours and across the entire 4 to 8 GHz frequency band, Gajjar and the Listen team analyzed the 400 terabytes of data gathered and found 15 new pulses from FRB 121102.

"The distinctive shape that the dispersion imposes on the initial pulse is an indicator of the amount of material between us and the source, and hence an indicator of the distance to the host galaxy", Breakthrough said in its report. Each of the 15 pulses lasted 300 milliseconds.

Researchers detected 15 powerful, repeating radio bursts coming from space for the first time on August 26.

It added: "Life on Earth consisted of only single-celled organisms, and it would be another billion years before even the simplest multi-cellular life began to evolve".

The analysis confirmed that the source is in a newly active state. Two, whatever happened has happened across a span of years; remember, these radio waves have to travel across space to be picked up by our telescope. But proving this assumption wrong, a team of scientists in 2016 published an article in the journal Nature where they revealed about the finding of repeating radio signals, coming from FRB 121102.

One of the astronomers, Avi Loeb, chairs the advisory committee for Breakthrough Starshot, an initiative that's related to Breakthrough Listen and aims to send swarms of interstellar probes through the Alpha Centauri system ... propelled by directed energy beams.

"We do know that the universe is capable of producing intelligent civilizations that can produce technology", said Siemion.
