FAST RADIO BURSTS

Fast Radio Bursts, or FRBs are blasts of radio energy that hit Earth from outside the milky way galaxy, lasting only milliseconds before they disappear. Dr. Avi Loeb of Harvard University and Harvard Smithsonian Center for Astrophysics discusses the possibility that they could be leakage from highly powerful lasers pushing on light sails or other signs of advanced extraterrestrial intelligence. As well as the interstellar object known as Oumuamua and if it is a solar sail or alien probe. Avi Loeb also discusses what are the most dangerous and immediate threats to life on earth from space, asteroid collisions, solar flares including the carrington event, and black holes.

We talk to SKA Project Scientist Evan Keane about the significance of the discovery of 20 new Fast Radio Bursts - doubling the known number of these mysterious objects - by ASKAP, one of the SKA precursor telescopes in Australia.

Scientists using a Western Australian radio telescope say they’ve significantly increased their detections of fast radio bursts.

Researchers used machine learning to discover 72 new fast radio bursts from a mysterious source 3 billion light years from Earth. Geek.com reports that in radio astronomy, fast radio bursts are high-energy astrophysical phenomenon of unknown origin; the bright pulses of radio emission last mere milliseconds and are thought to originate from distant galaxies. Their source, however, remains unclear. But Breakthrough Listen, a SETI project led by the University of California, Berkeley, hopes AI can help clarify. according to Andrew Siemion, director of the Berkeley SETI Research Center and principal investigator of Breakthrough Listen, “This work is exciting not just because it helps us understand the dynamic behavior of fast radio bursts in more detail, but also because of the promise it shows for using machine learning to detect signals missed by classical algorithms." https://www.geek.com/tech/ai-detects-more-mysterious-cosmic-radio-bursts-1751925/?source http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

Machine learning algorithms applied to Listen data from the Green Bank Telescope found new pulses from the mysterious repeating source FRB 121102. These new bursts were missed by conventional search methods, and are helping to answer questions about the origin of FRB 121102. Machine learning algorithms are also being applied to help Listen search for new kinds of candidate signals from extraterrestrial intelligence.

Fast Radio Bursts are millisecond-duration pulses of unknown origin that were discovered by astronomers in 2007. A decade later, with only two dozen bursts known, Fast Radio Bursts remain enigmatic sources which parallel the early days of gamma-ray burst astronomy in the 1970s. Professor Lorimer tells the story of Fast Radio Bursts’ discovery, summarize what we know so far, describe the science opportunities these bursts present, and make predictions for what we will learn in the next decade.

While the new findings don’t shed any fresh light on what causes them – the research has provided some new insights to the deep space environment in which they occur. *Underground Martian water ice deposits exposed New images have revealed eight sites on Mars where thick subsurface deposits of water ice have been exposed on the cliff faces of eroding slopes. As well as holding clues about the red planet’s climate history – the findings also show how frozen water may be far more accessible for future missions to Mars than previously thought. *The universe has far more massive stars than expected Astronomers have discovered an excess of massive stars being formed in a giant stellar nursery in our neighbouring galaxy -- the Large Magellanic cloud. The findings are based on observations of 30 Doradus -- the Tarantula nebula –the biggest star-forming region in our part of the universe and host to some of the most massive stars ever found. *Tabby’s star just dusty New research has supported earlier studies indicating strange uneven and sporadic variations in the light coming from a distant star is most likely just dust. For the last few years astronomers and the general public have been captivated by the mysterious changes in brightness coming from the star now commonly referred to as Tabby’s Star. *The Science Report New figures confirm 2017 was Australia’s third hottest year on record.

It started in 2001, a brilliant burst of light breached the skies. The event had released as much power as 500 million suns. Just a few milliseconds later, the signal had vanished. Astronomers call these powerful flashes Fast Radio Bursts (FRBs). Since 2001, about 30 have been identified. But, new estimates suggest one is happening almost every second. According to Dr. Avi Loeb, professor of science at Harvard University, "In the time it takes you to drink a cup of coffee, hundreds of FRBs may have gone off somewhere in the universe." The origins of FRBs continue to elude explanation. But there's one source unlike any other that may hold the key to solving the mystery. It's called FRB 121102. It's the only known FRB that repeats. Astronomers have observed over 150 flashes from FRB 121102. Its repeated signals suggest FRBs aren't from a single explosion. Rather, they could be from an unusual object called a magnetar. Magnetars are highly-dense stars with powerful magnetic fields. Whatever the reason, FRBs are proof there's still so much more to learn about our universe.

In recent years, scientists have discovered fast radio bursts, energetic single pulses of radio emission arriving in random directions from unknown sources well beyond our galaxy, the Milky Way. The origin of these pulses is a major puzzle in high energy astrophysics. With its huge field of view and broad frequency coverage, the CHIME telescope is a nearly ideal instrument for finding and studying many of these bursts, enabling scientists to tackle one of the most mysterious new areas of astrophysics.

BERKELEY, CALIFORNIA — Astronomers last month reported detections of radio bursts from a far away galaxy. Writing in the Astronomer's Telegram, scientists reported 15 fast radio bursts detected from a dwarf galaxy some 3 billion light years from our own. Scientists suggest the bursts may have come from a magnetar, which is a rotating neutron star with a strong magnetic field. Researchers also speculate that the bursts may originate from alien laser technology used to propel and power spacecraft, like wind powers sails on a ship, according to a University of California, Berkeley news release. That theory is similar to Breakthrough Starshot, an initiative aimed at propelling nanocraft to Proxima Centauri with Earth-based lasers. Whatever they came from, researchers say that those signals began travelling from their galaxy over 10 billion years ago, when ours wasn't even 2 billion years old. ----------------------------------------­--------------------- Go to https://www.patreon.com/tomonews and become a Patron now TomoNews is now on Patreon and we've got some cool perks for our hardcore fans.

The 11th talk of TeVPA 2017. I review our present observational understanding of the mysterious new phenomenon of Fast Radio Bursts -- short (few ms) bursts of radio waves arriving from apparently cosmological distances -- as well as models for what these sources may be. I also describe the CHIME telescope, currently being built in Canada, and how it will impact this interesting puzzle.

FRBs last just a few milliseconds, and astronomers have detected less than a couple dozen of them without our current telescopes. Where do scientists think they come from?

Profs Duncan Lorimer and Maura McLaughlin discuss what could be responsible.

Fast Radio Bursts are millisecond-duration pulses of unknown origin that were discovered by pulsar astronomers in 2007. A decade on from the discovery, with only 20 further bursts currently known, fast radio bursts remain enigmatic sources which parallel the early days of gamma-ray burst astronomy in the early 1970s.

What’s actually happening is that you’re tagging along as I learn more and more about new and cool things happening in the Universe. I dig into them like a badger hiding a cow carcass, and we all get to enjoy the cache of knowledge I uncover. Okay, that analogy got a little weird. Anyway, my point is. Squirrel! Fast radio bursts are the new cosmic whatzits confusing and baffling astronomers, and now we get to take a front seat and watch them move through all stages of process of discovery. Stage 1: A strange new anomaly is discovered that doesn’t fit any current model of the cosmos. For example, strange Boyajian’s Star. You know, that star that probably doesn’t have an alien megastructure orbiting around it, but astronomers can’t rule that out just yet? Stage 2: Astronomers struggle to find other examples of this thing. They pitch ideas for new missions and scientific instruments. No idea is too crazy, until it’s proven to be too crazy. Examples include dark matter, dark energy, and that idea that we’re living in a Stage 3: Astronomers develop a model for the thing, find evidence that matches their predictions, and vast majority of the astronomical community comes to a consensus on what this thing is. Like quasars and gamma ray bursts. YouTuber’s make their videos. Textbooks are updated. Balance is restored. Today we’re going to talk about Fast Radio Bursts. They just moved from Stage 1 to Stage 2. Let’s dig in. Fast radio bursts, or FRBs, or “Furbys” were first detected in 2007 by the astronomer Duncan Lorimer from West Virginia University. He was looking through an archive of pulsar observations. Pulsars, of course, are newly formed neutron stars, the remnants left over from supernova explosions. They spin rapidly, blasting out twin beams of radiation. Some can spin hundreds of times a second, so precisely you could set your watch to them. In this data, Lorimer made a “that’s funny” observation, when he noticed one blast of radio waves that squealed for 5 milliseconds and then it was gone. It didn’t match any other observation or prediction of what should be out there, so astronomers set out to find more of them. Over the last 10 years, astronomers have found about 25 more examples of Fast Radio Bursts. Each one only lasts a few milliseconds, and then fades away forever. A one time event that can appear anywhere in the sky and only last for a couple milliseconds and never repeats is not an astronomer’s favorite target of study. Actually, one FRB has been found to repeat, maybe. The question, of course, is “what are they?”. And the answer, right now is, “astronomers have no idea.” In fact, until very recently, astronomers weren’t ever certain they were coming from space at all. We’re surrounded by radio signals all the time, so a terrestrial source of fast radio bursts seems totally logical. About a week ago, astronomers from Australia announced that FRBs are definitely coming from outside the Earth. They used the Molonglo Observatory Synthesis Telescope (or MOST) in Canberra to gather data on a large patch of sky. Then they sifted through 1,000 terabytes of data and found just 3 fast radio bursts. Three. Since MOST is farsighted and can’t perceive any radio signals closer than 10,000 km away, the signals had to be coming outside planet Earth. They were “extraterrestrial” in origin. Right now, fast radio bursts are infuriating to astronomers. They don’t seem to match up with any other events we can see. They’re not the afterglow of a supernova, or tied in some way to gamma ray bursts. In order to really figure out what’s going on, astronomers need new tools, and there’s a perfect instrument coming. Astronomers are building a new telescope called the Canadian Hydrogen Intensity Mapping Experiment (or CHIME), which is under construction near the town of Penticton in my own British Columbia.

The team made the discovery using the old Molonglo radio telescope 40 kilometres from Canberra. Astronomers identify purest, most massive brown dwarf Astronomers have discovered the most massive brown dwarf ever seen. The record breaking object, known as SDSS J0104+1535 has the purest composition of any brown dwarf ever observed. Event Horizon telescope deployed to study black holes Astronomers have deployed a powerful array of telescopes to undertake the first ever detailed image of the black hole at the centre of our galaxy. The Event Horizon Telescope is an international joint effort to link some of the world’s most powerful radio telescopes to examine Sagittarius A Star -- a supermassive black hole some 4.3 million times the mass of our Sun – located some 27 thousand light years away – in the galactic centre. New Horizons already halfway from Pluto to its next target Nasa’s New Horizons spacecraft is now halfway from its close encounter with Pluto to its flyby of Kuiper Belt object 2014 MU69. The probe will encounter the distant world on January 1st 2019. Biggest wave ever recorded The World Meteorological Organization have announced confirmation of the biggest wave ever detected – measuring some 19 metres or 62.3 feet tall as tall as a six story building. The record breaking wave formed in the North Atlantic Ocean between the United Kingdom and Iceland.

Since the first discovery of Fast Radio Bursts (FRB) in 2007, the phenomena has perplexed astronomers. To date, 18 FRBs have been detected but FRB 121102 (discovered in 2012) was the first to repeat itself. This gave astronomers the ability to observe it for a long period of time and determine its location - a dwarf galaxy that is 3 billion light-years from Earth. -- Full Story: https://goo.gl/XzXXZo Credit: Gemini Observatory / Edited by Space.com's @SteveSpaleta http://www.twitter.com/stevespaleta

Now, we think that the rotation of young neutron stars may be the source of these intense energy bursts.

A team of astronomers reported it has come upon 10 fast radio bursts that appear to come from both far away and a solitary source. Ever since a radio burst coming from space was first identified 15 years ago, many astronomers have been searching for more, some hoping to detect repeat signals from the same entity.  While the latter sort of effort has not proven successful over the past decade and a half, that recently changed.  A team reported it has come upon 10 radio blips that appear to come from both far away and a solitary source.  The signals are technically called fast radio bursts, or FRBs and are often attributed to truly enormous cataclysms occurring in the universe, such as exploding stars. As the object creating the burst is decimated in the process, it would explain why up until now only once-occurring signals have been detected.  However, the potential existence of repeat signals indicates that other source possibilities exist.  The team suspects the origin of the multiple signals may be, according to the CBC, “a rotating neutron star like a pulsar, but much farther away.”  It also suggests there could be different types of FRBs.

For the first time ever, a fast radio burst (FRB) has been traced to its source location, a distant galaxy six billion light-years away.

The cosmic activity known as fast radio bursts, or FRBs, have remained a mystery to astronomers, but a recent study by an international team of researchers provides some startling insights into the phenomenon. The cosmic activity known as fast radio bursts, or FRBs, have remained a mystery to astronomers, but a recent study provides some startling insights into the phenomenon.  FRBs are flashes of radio signals that are typically over in milliseconds; before this paper, only 16 had been identified.  Because these events are fast, rare, and usually detected years after they happen, a team created an alert to go off should such activity be detected by Australia’s Parkes Radio Telescope. An FRB occurred on April 18th, and, based on the collected data, scientists were able to determine that it came from an elliptical galaxy around 6 billion light years away.  This galaxy is known to be old which discounts the theory that these bursts originate from young pulsars.  Instead, as one of the authors has stated, “It might mean that the FRB results from, say, two neutron stars colliding rather than anything to do with recent star birth.”

For almost 10 years, astronomers have been trying to track down the source of mysterious cosmic radiowaves called Fast Radio Bursts (FRBs), which are brighter than our Sun, packed with energy, and flash across the Universe in random directions thousands of times a day. http://sostrenews.com/study-finds-mysterious-cosmic-radio-waves-could-have-come-from-a-starquake/ http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

This narrated video describes the discovery of a new population of radio bursts that appear to come from cosmological distances that was published today in Science. The bursts offer a new way to count the number of atoms in the Universe and have mysterious origins.

Lightning in the clouds is directly linked to events that produce some of the highest-energy light naturally made on Earth: terrestrial gamma-ray flashes (TGFs). An instrument aboard NASA's Fermi Gamma-ray Space Telescope was recently fine-tuned to better catch TGFs, and this allowed scientists to discover that TGFs emit radio waves, too.
