Light pollution from SpaceX’s Starlink and other satellite internet constellations are causing trouble for astronomers. They’re urging policymakers to regulate satellite launches in a series of new papers published in the journal Nature Astronomy.
The swift rise of internet satellites, forming megaconstellations, and accumulating space junk are already starting to mess with astronomers’ research. The problem is growing exponentially, scientists warn in a series of papers published recently in the journal Nature Astronomy. And they want regulators to do something about it. The swarm of satellites functioning in low Earth orbit has more than doubled since 2019, when space-based internet initiatives really started to take off.
Light reflected by objects in low Earth orbit would increase the background brightness for the study by 7.5 percent by 2030 compared to an unpolluted night sky. That interference could cause the project’s costs to balloon by nearly $22 million, the researchers found. That’s because, with a brighter night sky, researchers have to increase exposure times to spot faraway objects. And scientists might miss more faint objects in a brighter sky, the paper warns.
