The night sky above the planned Extremely Large Telescope (pictured) will be only “moderately affected” by the numerous satellites being launched as part of communication ‘megaconstallations’. A European Southern Observatory study suggests strategies to mitigate the problem, such as closing the telescope shutter at the precise moment when a satellite crosses the field of view. The study assumes 26,000 constellation satellites in total will be orbiting the Earth, but this number could be higher. (ESO press release)
