NASA has tested a developmental cryocoupler that could help future spacecraft refuel in Earth orbit before setting out for deeper destinations. The work, conducted by engineers at NASA’s Marshall Space Flight Center with L3Harris, targets one of the hardest practical problems in future exploration: moving extremely cold rocket propellant between spacecraft without wasting it. The…

ESA/Hubble has released a new Hubble image of NGC 6723, a glittering globular cluster in Sagittarius that sits about 27,000 light-years from Earth. The scene looks delicate, but it belongs to one of the oldest classes of objects in the Milky Way. Inside its crowded glow, astronomers see evidence that this stellar “chandelier” formed through…
Researchers using the NASA/ESA/CSA James Webb Space Telescope report in a Nature study that interstellar comet 3I/ATLAS carries a chemical signature unseen in Solar System comets. The finding suggests that this visitor formed in a cold, distant planetary system that may predate the Sun by billions of years. The comet is only the third confirmed…
A study in One Earth led by researchers at King Abdullah University of Science and Technology has captured a troubling global picture of marine life during the first year when global temperatures temporarily exceeded 1.5°C above pre-industrial levels. Across the world’s oceans, the team documented 201 ecological impact events that included coral bleaching, harmful algal…
