New research finds that SpaceX's Starlink satellites are leaking radiation that could interfere with radio astronomy.
SpaceX's Starlink satellites are leaking radiation into the night sky as they circle Earth, which could be interfering with astronomers' attempts to pick up radio signals arriving from the farthest reaches of the cosmos, a new study shows.
The unintended radiation leak had been theorized previously, but this is the first time it has been observed directly, study lead author Federico Di Vruno, co-director of the International Astronomical Union's Centre for the Protection of the Dark and Quiet Sky from Satellite Constellation Interference, said in a statement.
SpaceX likely isn't the only culprit; the researchers expect to detect similar emissions from many other satellites in low Earth orbit . The problem also could worsen as the number of private satellites in LEO continues to increase dramatically. For example, there were only 2,000 Starlink satellites in LEO when the data was collected, but there are now more than 4,000.
