Astronomers watched 35 explosive outbursts from a rare repeating “fast radio burst” (FRB) as it shifted in frequency like a “cosmic slide whistle,” blinking in a puzzling pattern never seen before.

FRBs are millisecond-long flashes of light from beyond the Milky Way that are capable of producing as much energy in a few seconds as the sun does in a year. FRBs are believed to come from powerful objects like neutron stars with intense magnetic fields  —  also called magnetars  —  or from cataclysmic events like stellar collisions or the collapse of neutron stars to form black holes. Complicating the FRB picture, a few FRBs are “repeaters” that flash from the same spot in the sky more than once, while the majority burst once and then vanish.

    I don’t know or care to speculate what it could be with my limited knowledge of astrophysics. However it’s awesome how many strange things are still out there.

    It’s never a cosmic slide whistle until you’ve ruled out everything else. This could be interference from Dee-Lite. It could be Sixpence None the Richer. It could be aliens with a regular slide whistle but using an amplifier to make it seem like a cosmic slide whistle.

    A alien hunting telescope picking up something that defines explanations, is sort of what I expected from alien hunting telescope news, to be honest.

    But it is cool nevertheless.

    A couple of posts back on my feed was about nasa sending a video of a cat via a laser beam. Can’t help thinking they’ve been intergallactically rick-rolled!
