The weird, repeating signals from deep space just tripled
Fast radio bursts are getting more attention from scientists, who can now detect more of them.

We're picking up more signals from deep space.

Scientists suddenly have a whole lot more data on one of the strangest and most recent mysteries in the cosmos, so-called fast radio bursts. First discovered in 2007, these fleeting blasts of radio waves originate thousands, millions or even billions of light-years from Earth.

FRBs have influenced the design of new radio telescopes like the Canadian Hydrogen Intensity Mapping Experiment (CHIME). And now a team of Canadian and American researchers using CHIME has reported a major new set of FRB detections that could fine-tune our understanding of where these enigmatic signals come from and what produces them.

The group says it's discovered eight new bursts that repeat.

"Repeating FRBs are highly valuable from an observational perspective since their repeating nature make them better candidates for localizing their host galaxies and multi-wavelength follow-up observations that can help determine if FRBs emit at wavelengths other than radio," said Ryan McKinven, one of the researchers who is based at the University of Toronto and co-author of a paper about the FRBs.

Those follow-up observations could provide details about the origins of the strange bursts, he added. A larger sample size of repeating FRBs to study could also help scientists answer one of the obvious questions about non-repeating FRBs: Could they actually be repeating FRBs that just haven't been recorded as repeating yet?

While dozens of FRBs have been detected and cataloged over the past 12 years, few of those deep space signals had been known to repeat themselves. Two have been documented so far in published, peer-reviewed journals. Two others -- one via a Russian radio telescope, the other via Australia -- have been reported but not yet reviewed.

So with this batch of bursts, the number of reported repeaters has tripled -- from four to 12.

The team laid out its findings in a draft paper that's been submitted to the Astrophysical Journal and was posted this month on the Arxiv pre-print site.

"Discovering different types of FRBs at an unexpected rate, we will soon open new windows into understanding the cosmological origin of these high-energy astrophysical phenomena," said co-author Masoud Rafiei-Ravandi of the Perimeter Institute for Theoretical Physics.

In addition to the sheer number of repeating FRBs discovered in one haul, one of the newfound repeaters appears to be much closer to Earth than the handful of fast radio bursts that have been traced back to a source galaxy. So far, traceable FRBs seem to come from sources on the other side of the universe -- we're talking billions of light-years away.

However, in the new paper, the authors suggest that one of the repeating FRBs could actually originate near the edge of our own Milky Way galaxy but caution that more study is needed to better localize the signal.

"Knowing that we are observing every patch of sky visible to CHIME once every day, it was only a matter of time before we detected a very nearby source," co-author Pragya Chawla of McGill University said.

Studying relatively nearby FRBs will hopefully allow scientists to get a better idea of just what the heck is throwing off these signals, which could be anything from far-fetched notions like alien starships to the less fantastic but more powerful sources, like neutron stars.

I get that everything including collisions of massive objects put out energy in all forms including radio. The fact they're repeating is fascinating to say the least. I'm assuming they can differentiate between massive neutron stars spinning at millions of miles per hour and gamma ray bursts that spin like light house lights from these FSBs. Great times to be alive if you're into expanding your knowledge in celestial events.

After the unusual discovery of the interstellar object that swung through our solar system, there seems to be another coming in. The link is from a group chat of professional and amateur comet hunters. They’ve discovered another one. Heading this way. It’s expected to close in on our star in December and continue on its way. It’s still far enough away that they’re not sure on its size due to its reflection. If it’s as dark as asphalt it’s determined to be 25km long. If it’s very reflective as say our moon, it’s determined to be closer to 6km long.

The first was a probe now comes the destroyer:runaway:

I cannot find my glasses or car keys when they are right in front of me. Simply amazing, staggering, to think these guys can spot something that could possibly be compared be the equivalent of the smallest grain of sand in the middle of 5 million Sahara Deserts.

It’s the love of the pursuit. You find it, you name it and live on forever. Most of these guys gave up families and income and life so they can rise at 10pm and go sit in remote corners of the world and watch the sky until sunrise. Once you’ve done that for about a decade, you develop you’re own star map of your favorite thumbnail of the heavens. They compare that map everyday with the newly created map of the data from the night. Anything moving is immediately passed on to nasa jet propulsion and cal tech. From there it spreads like fire. Within 24 hours, flies on the wall like me get to read about it before the majors even knew what happened. Gotta love the internet.

Continuing on with the detection of radio signals:

A Mysterious Deep Space Radio Burst Is Sending Signals To Earth Every 16 Days

A mysterious object in a galaxy 500 million light-years away is confusing scientists with its signals. It appears to be transmitting signals that reach Earth in a repeating, 16-day pattern, but researchers have no idea why.

According to a recent study, this marks the first time astronomers have detected a reliable pattern in the signals, known as fast radio bursts, or FRBs. It's an important step in figuring out where the bursts originate from.

Before now, such pulses appeared to be random in timing. That changed when the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst Project (CHIME/FRB) discovered a repeating pattern.

The recently detected FRB, known as FRB 180916.J0158+65, sends out bursts that last for four days before stopping for 12 days and then repeating. The first 28 cycles were observed between September 2018 and October 2019 using the CHIME radio telescope in British Columbia.

"We conclude that this is the first detected periodicity of any kind in an FRB source," the study's authors said. "The discovery of a 16.35-day periodicity in a repeating FRB source is an important clue to the nature of this object."

Scientists recently pinpointed this specific FRB to a spiral galaxy known as SDSS J015800.28+654253.0, located half a billion light-years from Earth — making it the closest FRB ever detected. Researchers hope that tracing the burst's origin will help them to determine what caused it.

The first FRB was spotted in 2007, and the signals have mystified scientists ever since. They only last for a thousandth of a second, making them difficult to study. Hundreds have been spotted, but only a handful have ever repeated themselves — and they seem to come from locations all over the universe.

While the cause of the repeating pattern is unknown, researchers said the FRB could be orbiting a black hole-like object, flashing its signal at a specific point in its orbital period.

According to another study looking at the same data, the pattern could be consistent with that of a binary star system containing a massive star and a dense neutron star. The neutron star could be emitting the bursts, which are sometimes hidden by winds caused by its massive friend.

"Fast radio bursts are exceedingly bright given their short duration and origin at great distances, and we haven't identified a possible natural source with any confidence," Avi Loeb, a Harvard-Smithsonian Center for Astrophysics theorist, said in a press release back in 2017.

There is one source most scientists have generally ruled out: aliens. But discovering more repeating FRBs may be the only way to know for sure.
