Researchers analyzing crimson auroras over Japan found the glowing displays stretched hundreds of miles higher into Earth’s atmosphere than expected, challenging long-held assumptions about the strength of geomagnetic stor…
On May 21, ground controllers powered down NASA’s AWE (Atmospheric Waves Experiment) instrument, bringing the data collection phase of the mission to a successful and scheduled end, surpassing its planned two-year mission. Installed on the exterior of the International Space Station since November 2023, AWE studied atmospheric gravity waves, which are giant ripples in the […]
Scientists studied how space junk moved in orbit over a 36-year span, finding that increased solar activity caused it to fall to Earth faster.

A new Sun-centered and science-focused coloring book produced by NASA in partnership with the University of Alaska Fairbanks (UAF) is now available for people to learn while showing their artistic side.
Earth’s magnetic field is like a powerful trap. It lures electrically charged particles in space, near our planet, and snares them in an invisible, doughnut-shaped pen around Earth known as the ring current. This captive swarm of charged particles plays an important role in how Earth reacts to changing conditions in space, called space weather, which […]
The twin eruptions briefly disrupted radio signals across the dayside of Earth.
Acting as stellar archaeologists, scientists have found fossilized magnetism on long-dead white dwarf stars, which may help to explain how stars evolve.
