Space and Astronomy

A NASA-led, peer-reviewed study published in Nature on Dec. 3, 2025 warns that reflected light from rapidly growing satellite constellations could contaminate up to 96% of images from some space telescopes within a decade, with at least one in three Hubble images expected to show a satellite streak. The analysis cites more than 10,000 active satellites (including ~7,800 SpaceX Starlink units) and forecasts major impacts on NASA’s SPHEREx as well as ESA’s ARRAKIHS and China’s Xuntian, while the American Astronomical Society and the U.N.’s ITU voice concern and SpaceX points to mitigation steps like visors and darker coatings.
