A team of astronomers and astrophysicists affiliated with several institutions in Australia has found that a mysterious fast radio burst (FRB) detected last year originated not from a distant source, but from one circling the planet—a long-dead satellite. The team has posted a paper outlining their findings on the arXiv preprint server.
When are we going to do something about all these zombie satellites and other space junk just floating in a fixed orbit around earth for all eternity? We really should send somebody up there to clean up that mess.
