We’re living in the future, for sure.

Why do I say that, you ask? Well, a few scientists have recently discovered that, in a galaxy, far, far away...something is sending radio waves our direction. Now, before you get excited at the thought of visitors from benevolent galaxies, or terrified that green tentacled horrors are invading, be aware that the “something,” I just mentioned - is probably "nothing." In fact, GCN's very own paranormal phenomenon radio program, "The Paracast," (host: Gene Steinberg) brings all this up in the opening of their most recent program, which you can find here.  

And now, I would like to mention that when I wrote “nothing," up above, I did not mean “absolutely nothing,” just - probably, not aliens. The most likely theory being tossed around is that the radio signals are created by, “astrological phenomenon.” Editor's note: Which, thanks, by the way, Scientist Folks - because "astrological phenomenon"  tells us absolutely nothing at all! The phrase could literally mean "anything happening out in space!" (But, in this case, probably means something like - a black hole).  

Anyway, this is not the first time radio waves have been discovered heading our direction. In the way back time of 2007 (before there was even an iPad!) an astrophysicist at Australia's Parkes Observatory was analyzing data from 2001 and discovered radio bursts. Movie pun not intended. That’s actually when it happened. Of course, astronomers of the day were skeptical and most thought it was just "interference;" but he published his findings and has since been proven accurate. And now we have multiple “fast radio bursts” on record but the 2007 case, and now a brand new one uncovered a few days-have something unique in common - a repeating signal.

Now, to my understanding (which, is limited to some very recent Googling, lots of wiki reading and some science journal perusing) the 2001 burst had a “single repeating fast radio burst.” The Jan. 9th, 2019 discovery has - six repeat bursts. Which as far as I understand, is extremely unusual to find that many repeating bursts occurring naturally; and while it certainly does not prove the existence of our beloved masters and eventual overlords … errr, I mean, aliens … it is still cool.

From the Jan. 9th, 2019 study reported in Journal:  

The discovery of a repeating fast radio burst (FRB) source. 1,2, FRB 121102, eliminated models involving cataclysmic events for this source. No other repeating FRB has hitherto been detected despite many recent discoveries and follow-ups. 3–5, suggesting that repeaters may be rare in the FRB population. Here we report the detection of six repeat bursts from FRB 180814.J0422+73, one of the 13 FRBs detected. 6 by the Canadian Hydrogen Intensity Mapping Experiment (CHIME) FRB project7 during its pre-commissioning phase in July and August 2018. These repeat bursts are consistent with originating from a single position on the sky, with the same dispersion measure, about 189 pc cm−3. This traces approximately twice the expected Milky Way column density, and implies an upper limit on the source redshift of 0.1, at least a factor of about 2 closer than FRB 1211028. In some of the repeat bursts, we observe sub-pulse frequency structure, drifting, and spectral variation reminiscent of that seen in FRB 1211029,10, suggesting similar emission mechanisms and/or propagation effects. This second repeater, found among the first few CHIME/FRB discoveries, suggests that there exists—and that CHIME/FRB and other wide-field, sensitive radio telescopes will find—a substantial population of repeating FRBs.”
