[ICYMI] Astronomers sound alarm about light pollution from satellites
Astronomers have warned "our ancient relationship with the night sky" is at risk due to light pollution caused by satellitesAstronomers on Monday warned that the light pollution created by the soaring number of satellites orbiting Earth poses an"unprecedented global threat to nature."
Each new satellite increases the risk that it will smash into another object orbiting Earth, creating yet more debris. In one paper, 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 of Dark Sky Consulting, a firm based in the US state of Arizona.
"Space is our shared heritage and ancestor -- connecting us through science, storytelling, art, origin stories and cultural traditions -- and it is now at risk," she said in a Nature comment piece.
