Scientists Pin Down the Origins of a Fast Radio Burst

(Wednesday January 01, 2025 @10:30PM (msmash) from the ticket-closed dept.)


MIT scientists have pinpointed the origin of a fast radio burst (FRB) to [1]within 10,000 kilometers of a neutron star , settling a long-standing debate about these cosmic phenomena. Using a novel technique analyzing signal scintillation, researchers determined that FRB 20221022A, detected in 2022 from a galaxy 200 million light-years away, emerged from the star's turbulent magnetosphere rather than from a distant shockwave.

The findings, [2]published in Nature , provide the first conclusive evidence that FRBs can originate in the extreme magnetic environment immediately surrounding these ultra-compact objects.

Gee, I wonder where those radio bursts are coming from?

"from a galaxy 200 million light-years away"

10,000 km out of 200MLy ?

I don't think we can measure that accurately with our telescopes

My ritual differs slightly. What I do, first thing [in the morning], is I
hop into the shower stall. Then I hop right back out, because when I hopped
in I landed barefoot right on top of See Threepio, a little plastic robot
character from "Star Wars" whom my son, Robert, likes to pull the legs off
of while he showers. Then I hop right back into the stall because our dog,
Earnest, who has been alone in the basement all night building up powerful
dog emotions, has come bounding and quivering into the bathroom and wants
to greet me with 60 or 70 thousand playful nips, any one of which -- bear
in mind that I am naked and, without my contact lenses, essentially blind
-- could result in the kind of injury where you have to learn a whole new
part if you want to sing the "Messiah," if you get my drift. Then I hop
right back out, because Robert, with that uncanny sixth sense some children
have -- you cannot teach it; they either have it or they don't -- has chosen
exactly that moment to flush one of the toilets. Perhaps several of them.
