Satellite constellations could obscure most space telescope observations by late 2030s: ‘That part of the image will be forever lost’
Rapidly growing swarms of satellites around Earth are no longer just a nuisance for ground-based observatories — the reflections they cause are now intruding on space-based telescopes as well, according to new research.
Roughly 15,000…
