Astronomers have detected a weird heart-shaped radio signal from space. It's a fast radio burst (FRB) whose origin is one of the biggest unsolved problems in astronomy. The signal is unusually long: about 3 seconds, and has bursts of high-intensity radiation every 0.2 milliseconds. The 17th episode of the Sunday Discovery Series explains this discovery and the mystery of the Fast Radio Bursts.

Fast Radio Bursts (FRBs) are short (few millisecond) bursts of radio waves observed from cosmological distances. Their origin is presently unknown, yet their rate is many hundreds per sky per day, indicating a not-uncommon phenomenon in the Universe. In this talk, Professor Kaspi reviewed the FRB field and presented new results on FRBs from a new digital transit radio telescope, the Canadian Hydrogen Intensity Mapping Experiment (CHIME). This is the Bakerian Lecture 2021 delivered by Professor Victoria Kaspi CC FRS The Royal Society is a Fellowship of many of the world's most eminent scientists and is the oldest scientific academy in continuous existence.

SETI@home: New SETI Perspectives article Richard M Lawn has posted another interesting article to the SETI Perspectives forum. This one is about the mysteries of Fast Radio Burst (aka FRBs) , possibly some of the most distant explosions ever seen.

Fast Radio Bursts (FRBs) have become a major focus of research in the past decade. In radio astronomy, this phenomenon refers to transient radio pulses coming from distant cosmological sources, which typically last only a few milliseconds on average. Since the first event was detected in 2007 (the “Lorimer Burst”), thirty four FRBs have been observed, but scientists are still not sure what causes them.

Fast-Radio Bursts (FRBs) are one of the most puzzling phenomena facing astronomers today. Essentially, FRBs are brief radio emissions from distant astronomical sources whose cause remains unknown. In some cases, FRBs that have been detected that have been repeating, but most have been one-off events. And while repeating sources have been tracked back to their point of origin, no single events have ever been localized.

Bannister and his colleagues found the FRB using the Australian Square Kilometre Array Pathfinder (ASKAP), a network of 36 radio telescopes at CSIRO’s Murchison Radio-astronomy Observatory in Western Australia. They detected the burst on Sept. 24, 2018, which explains its name — FRB 180924. (The repeater FRB 121102 was first spotted in 2012, as you may now have surmised.)

The models will get stronger and stronger as more and more FRBs are pinpointed using the methods pioneered by Bannister and his team. And there are other exciting implications of the find as well.

“This FRB, like others detected, is thought to originate from outside of Earth’s own Milky Way galaxy,” says Shannon, “which means their signal has travelled over many hundreds of millions of light years, through a medium that – while invisible to our eyes – can be turbulent and affected by magnetic fields. It is amazing how these very few milliseconds of data can tell how weak the magnetic field is along the travelled path and how the medium is as turbulent as predicted.”
Using FRBs as cosmological probes has been made difficult by the uncertainty about their origins, which is why FRB 150807 is so helpful — we can reconstruct its path. The archival images the team is using show three stars and six galaxies that are possible sites (see image below). The brightest galaxy is between 1 and 2 gigaparsecs away — roughly between 3.3 and 6.6 billion light years. The other galaxies are fainter than this object by factors of 6 and more, and all are thought to be more than 500 Mpc (1.6 billion light years) distant. This assumes, of course, that we can associate the burst with a star or a galaxy.

For 35 years, scientists and astronomers have been intrigued by a mysterious signal arriving from space every 22 minutes. This relentless pattern has sparked a multitude of questions and theories about its origin and meaning. Is it a natural cosmic phenomenon, or could it be an attempt at communication from an extraterrestrial intelligence?
Five hundred million light-years from Earth, there is a deeply unusual object. It is radio silent for 12 days, then erupts in bright radio bursts. These fast radio bursts occur randomly over four days, then the object goes silent for another 12 days. Astronomers have observed this object for 500 days, and the pattern always repeats, like clockwork. We still aren’t sure what the object is.

Recently, two ground-based radio telescopes detected a pulse of radio waves. And it was pretty intense. This event astonished astronomers because it was the first time a fast radio burst (FRB) had ever been detected so close to Earth. But where does this signal come from? What caused this strange signal detected? Subscribe for more videos ► Patreon ► Business Enquiries ► The first FRB was discovered in 2007, although it was actually observed some six years earlier, in archival data from a pulsar survey of the Magellanic Clouds. It was dubbed the “Lorimer Burst”. Well, we must consider that magnetar is known to emit high energy electromagnetic radiation, such as gamma rays and X rays, the most powerful radiation in the universe. Both of these erupt in short-lived flares. That's why magnetar is a good candidate for causing Fast radio bursts. Also, this latest fast radio burst, which was dubbed FRB 200428, was found to have originated in the Vulpecula constellation, which....guess what? Happens to be hosting the magnetar SGR 1935+2154. The first detection of X-rays from that sky region came the day before CHIME and STARE2 "If You happen to see any content that is yours, and we didn't give credit in the right manner please let us know at A HREF="Lorenzovareseaziendale@gmail.com"> and we will correct it immediately" "Some of our visual content is under. an Attribution-ShareAlike license in its different versions such as 1.0, 2.0, 3,0, and 4.0 – permitting commercial sharing with attribution given in each picture accordingly in the video."

In a new survey, astronomers using the Hubble Space Telescope have managed to pinpoint the location of several Fast Radio Bursts (FRBs). FRBs are powerful jets of energy that, until recently, had mysterious, unknown origins. The research team, which includes University of California Santa Cruz’ Alexandra Manning and Sunil Simha, as well as Northwestern University’s Wen-fai Fong, performed a survey of eight FRBs, from which they were able to determine that five of them originated from a spiral arm in their host galaxies.

Fast radio bursts, or FRBs, are extraordinary events that generate as much energy in a thousandth of a second as the Sun does in an entire year! Astronomers using NASA’s Hubble Space Telescope have traced the locations of five brief, powerful FRBs, which are near or on their host galaxies' spiral arms. The research helped rule out some of the possible stellar objects originally thought to cause these brilliant flares.

The energetic phenomena known as Fast Radio Bursts (FRBs) are one of the greatest cosmic mysteries today. These mysterious flashes of light are visible in the radio wave part of the spectrum and usually last only a few milliseconds before fading away forever. Since the first FRB was observed in 2007, astronomers have looked forward to the day when instruments of sufficient sensitivity would be able to detect them regularly.

Fast Radio Bursts (FRBs) are among the most mysterious astronomical phenomena facing astronomers today. While hundreds of bursts have been detected since the first-ever recorded detection of an FRB in 2007 – the Lorimer Burst – astronomers are still unsure what causes them. Even more mysterious, some have occasionally been found to be repeating in nature, which has fueled speculation that they may not be natural in origin (i.e., possible alien transmissions?). Astronomers are naturally very excited whenever a repeating FRB is found, as it gives them the chance to examine them closer.
