The average number of satellite trails visible in each exposure is shown in relation to both the number of artificial satellites orbiting Earth (lower x axis) and epoch (upper x axis). Blue, SPHEREx; red, Xuntian; purple, ARRAKIHS; black, Hubble Space Telescope. Contours represent the 95% confidence levels for the mean number of trails. Horizontal solid line indicates one trail per exposure critical contamination level; vertical dotted line marks the current number of active and inactive satellites in orbit (15,000 as of March 2025).

For Immediate Release Contact: Michael Judson November 20, 2025 (Hickenlooper) (303) 482-7681 Hickenlooper, Crapo Reintroduce Bill to Protect Night Sky, Aid Research WASHINGTON - Today, U.S. Senators John Hickenlooper and Mike Crapo reintroduced their bipartisan Dark and Quiet Skies Act, which would preserve the night sky from unintentional light and radio interference that disrupts industry and academic space research. “There's bipartisan agreement that we need a strong space economy and cutting-edge scientific research to unlock the mysteries of our universe,” said Hickenlooper. “The Dark and Quiet Skies Act helps us do both. This is a no-brainer solution, and we're pushing to get it done.”
