Orbiting satellites could start crashing into one another in less than 3 days, theoretical new 'CRASH Clock' revealsResearchers have proposed a theoretical timepiece, dubbed the "CRASH Clock," which tells us how quickly satellites would start colliding if they lost the ability to avoid each other, such as during a powerful solar storm. And its value is rapidly decreasing.

What goes up must come down: How megaconstellations like SpaceX's Starlink network pose a grave safety threat to us on EarthOpinion Thousands of satellites with incredibly short lifetimes are being sent up into low Earth orbit. When they fall back down they're fireballs of pollution — and what doesn't burn up hits the ground.

'No radio astronomy from the ground would be possible anymore': Satellite mega-swarms are blinding us to the cosmos — and a critical 'inflection point' is approachingInvisible radiation leaking out of private satellites, like SpaceX's Starlink spacecraft, is disrupting radio astronomers' ability to detect important signals from across the universe. If left unchecked, we could reach an "inflection point" beyond which we can no longer properly study the cosmos, researchers warn.
