Can humans have babies in space? It may be harder than expected
Sperm struggles to find its way to an egg in microgravity, suggesting mammalian reproduction in space may not be possible.
'This is really intolerable': Astronomers protest giant orbiting mirror project and SpaceX's million AI satellites
Proposed constellations of orbiting mirrors and data centers would completely destroy the night sky as humanity has known it for millions of years, experts say.
An AI cyberattack could trigger a satellite apocalypse in the next 2 years. Are we prepared?
AI could soon be able to hijack satellites and cause them to collide with other spacecraft, triggering a cascade that could render Earth orbit unsafe.
SpaceX plan for 1 million orbiting AI data centers could ruin astronomy, scientists say
SpaceX's plan to launch one million orbiting data centers to space worries astronomers, who say the satellite streaks caused by the proposed constellation would severely impair observations.
Spectacular fireball over Europe sends meteorite crashing through roof of German home
A meteorite has crashed through the roof of a house after thousands observed a stunning fireball streak across the sky in western Europe.
