Astronomers on Monday warned that the light pollution created by the soaring number of satellites orbiting Earth poses an 'unprecedented global threat to nature.'

Blanco 4-meter Telescope flanked by two telescopes of the SMARTS Consortium in this image from Cerro Tololo Inter-American Observatory, a Program of NSF’s NOIRLab. Above the telescopes are the Large and Small Magellanic Clouds, while the Milky Way streaks across the lefthand side of the image.
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. In a series of papers published in the journal Nature Astronomy, astronomers warned that this increasing light pollution threatens the future of their profession.
That would reduce the number of stars the observatory is able to see by around 7.5 percent, study co-author John Barentine told AFP. Aparna Venkatesan, an astronomer at the University of San Francisco, said it also threatened "our ancient relationship with the night sky".
