that the light pollution created by the soaring number of satellites orbiting Earth poses an"unprecedented global threat to nature".
An armada of new internet constellations are planned to launch soon, adding thousands more satellites to the already congested area fewer than 2,000 kilometers above Earth. This can create a chain reaction in which cascading collisions create ever smaller fragments of debris, further adding to the cloud of"space junk" reflecting light back to Earth., astronomers warned that this increasing light pollution threatens the future of their profession., researchers said that for the first time they had measured how much a brighter night sky would financially and scientifically affect the work of a major observatory.
That would add nearly a year to the observatory's survey, costing around $21.8 million, said Barentine ofHe added that there is another cost of a brighter sky that impossible to calculate: the celestial events that humanity will never get to observe.study used extensive modelling to suggest that current measurements of light pollution are significantly underestimating the phenomenon.
