With no fuel or engines, tiny explorers will surf sun-warmed air alone to explore high in the skies of Earth and Mars

South Korea's K-RadCube satellite has arrived at NASA's Kennedy Space Center in Florida ahead of its launch toward the moon on the Artemis 2 mission next year.

Scientists are calling attention to an extremely common health problem that's been making astronauts uncomfortable: sinus issues.

This is part of a NASA-supported project hoping to fabricate "device-ready" wafers from space-grown crystals.

Southern Europe is once again in the grip of extreme summer heat. Soaring temperatures and bone-dry land have fuelled widespread wildfires, with the Iberian Peninsula among the regions hardest hit. Flames continue to sweep across parched landscapes, as these images show.

People in prisons and jails have contributed to some of the greatest ideas in mathematics

Warhammer 40K's most iconic real-time strategy series is back next year and under new leadership.

Traditional biology has long ignored nature’s sexual diversity—but evolution tells a far more complex story.

An automated system co-developed by SpaceX prevents disruption to radio astronomical observations caused by megaconstellations in low Earth orbit.

What lies in the heart of Orion?

A distant galaxy nicknamed "Cosmic Grapes" is bursting with massive star-forming clumps — far more than expected — offering fresh clues about how galaxies grew in the early universe.

Our Moon is a seismically active world and its long history of quakes could affect the safety of permanent base structures there. That's one conclusion from a study of quakes along the Lee-Lincoln fault in the Taurus-Littrow valley where the Apollo 17 astronauts landed in 1972. “The global distribution of young thrust faults like the Lee-Lincoln fault, their potential to be still active and the potential to form new thrust faults from ongoing contraction should be considered when planning the location and assessing stability of permanent outposts on the Moon,” said Smithsonian senior scientist emeritus Thomas R. Watters, lead author of the paper.

Supercomputer simulations are helping scientists sharpen their understanding of the environment beyond a black hole’s "shadow," material just outside its event horizon.
