More like "powerful radio emissions from deep space". The paper doesn't use the term "signal" at all, and a website dedicated to science probably shouldn't have either (although it did help bait my click).

I think the click-bait title is the reason why most comments here are about aliens.

Also because it has a set interval. People like to assume there is some intelligent life form that trigger the events.

But on our own planet we have geysers that erupt at set intervals. All without the help of an intelligent life form.

So I think it's more likely that it's a natural phenomena.

FRBs are chirps. Something like a "signal". Much more signally than the hiss from stars and galaxies.
