More Mysterious Radio Bursts Were Detected Radiating From Space
Another series of mysterious “fast radio bursts” (FRBs) has been detected by a new telescope in Canada, emanating from somewhere deep in the cosmos. The last detection of FRBs came last year, picked up by Breakthrough Listen, a project focused on detecting signs of intelligent extraterrestrial life.
FRBs are a series of incredibly short, powerful radio emissions in millisecond lengths, coming form an unknown source, lightyears away. Signals were detected last year, named FRB 121102, and were the first repeating radio bursts ever discovered, believed to be emitting from a distant neutron star — the highly dense core of a collapsed star.
The source of the latest signals could be a number of things, including an exploding black hole, magnetar, a spinning pulsar known as a blitzar, or the most exciting prospect; a highly advanced extraterrestrial race.
The frequency of these signals, named FRB 180725A, are the first of their kind to be detected below 700 mHz. The FRBs earlier this year were above 800 mHz, with scientists calculating their source to be some 3 billion lightyears away. The source would have emanated the same amount of power in each burst as our sun does in an entire day.
If these mysterious waves are coming from an extraterrestrial civilization, their setup would be equivalent to two Earth-sized generators, and would likely exist as a power source for spacecraft, rather than simply sending signals into the universe to make their presence known.
The signals were detected by the Canadian Hydrogen Intensity Mapping Experiment (CHIME) in British Columbia, a telescope that has been operating for under a year, with the primary goal of detecting FRBs. The telescope constantly scans 1,024 individual points in the sky 24/7, at 16,000 different frequencies, 1000 times per second; talk about an advanced piece of technology.
The first FRBs were discovered about a decade ago, making them one of the newest cosmological phenomena monitored by astrophysicists. Only a few dozen of these radio bursts have been detected since their initial discovery and scientists still consider the extraterrestrial explanation plausible.
Now that the CHIME telescope is solely focused on the signals, it may only be a matter of time until evidence of an intelligent extraterrestrial source are discovered. If they are from an advanced civilization, let’s just hope it still exists, considering these signals would have been sent millions or even billions of years ago.

What's Sending These Mystery Signals From 4,000 Lightyears Away?
A mysterious repeating radio signal from space has been detected that scientists have not seen before. What or who is sending this signal?
Scientists have detected a radio signal from somewhere out in deep space some 4,000 light-years away.
The signal pulsed every 18 minutes and 18 seconds, for 30 to 60 seconds — every time, 18 minutes and 18 seconds. It did this for three months then it stopped. Scientists assume it is a naturally occurring rotating object that, like a lighthouse shining its beacon, will send what appears to be a repeating signal.
But Natasha Hurley-Walker, whose study into this repeating signal was recently published in the journal Nature told Vice, “[T]here are no models that produce such bright radio emission from two objects in orbit with each other, with such precision, and any that would produce any kind of radio waves would also produce X-ray emission, which we don’t see.”
Some think this might be coming from a highly magnetized star called a magnetar. So what does this all mean? Astronomer and Gaia News contributor Marc D’Antonio weighed in on the subject.
“Maybe this strange signal is some weird kind of magnetar that is rotating, but we’re not used to seeing it rotate every 18 minutes, that means a rather slow rotation. So, this is kind of weird, it’s something that doesn’t match any model that we know, and I think it takes us down a new research path to try to figure out just what it is we’re looking at,” D’Antonio said.
