What seemed a lucky break — the discovery of a gamma-ray burst in the most distant known galaxy — might instead be the flash of passing space debris. As satellites fill low-Earth orbit, such events might become common. The post Did Astronomers See a Distant, Dying Star? Or an Earth-bound Satellite? appeared first on Sky & Telescope.
