The human heart shrivels away in space, but researchers have found that mini-hearts grown from human stem cells sprout in space significantly faster than in labs on Earth.
AI algorithms can sharpen naturally blurry images taken by ground-based telescopes, revealing details otherwise visible only to space-borne machines like Webb and Hubble.
"In the inner corona, a region very difficult to observe, we saw slow solar wind gusts moving three to four times faster than expected."
A crew of tiny worms will spend six months aboard the International Space Station, helping researchers better understand how long-term spaceflight affects human astronauts.
Artificial lights at night brightened up planet Earth by 16% from 2014 to 2022, a new study using satellite images has found.
Sperm struggles to find its way to an egg in microgravity, suggesting mammalian reproduction in space may not be possible.
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.
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'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.
