Numerous stories have been written about the growing swarm of Starlink satellites in low earth orbit (LEO) over the past few years, as astronomers grow increasingly worried about the crafts' impact on their observation equipment. Launched by Elon Musk's SpaceX, each satellite has the potential to disrupt astronomy through both radio emissions and light pollution - and as the number of satellites grows, so too does the amount of interference. Now, a new study by researchers at NASA is warning that obstructions caused by SpaceX and other private satellite companies are becoming so severe that not even the Hubble Space Telescope is safe.

Today the globe is circled by thousands of active satelliteseach prone to photobombing astronomers' telescopes as an artificial star zipping across the night sky. Scientists working with ground-based observatories such as the cutting-edge Vera C. Rubin Observatory have long worried about this visual interferencebut as satellites continue to proliferate, space-based telescopes, including the beloved Hubble Space Telescope, are beginning to suffer, too. And the problem is only going to get worse.
