"Stellar activity and plasma turbulence near a transmitting planet can broaden an otherwise ultra-narrow signal, spreading its power across more frequencies and making it more difficult to detect in traditional narrowband searches."

Maybe there's some alien civilization who's actively pointing a radio signal in our direction so they can communicate with us. I don't know.... maybe the aliens are observing how friendly we are to each other and really want to connect?

Yeah! Like, hmmmm... was it really a storm that brought Arecibo down? Or ... was the storm just used as a cover by ET hackers?
