An unexpectedly strong solar storm rocked our planet on April 23, 2023, sparking auroras as far south as southern Texas in the U.S. and taking the world by surprise. Two days earlier, the Sun blasted a coronal mass ejection (CME) — a cloud of energetic particles, magnetic fields, and solar material — toward Earth. Space scientists […]

NASA Launching Rockets Into Radio-Disrupting Clouds
NASA is launching rockets from a remote Pacific island to study mysterious, high-altitude cloud-like structures that can disrupt critical communication systems. The mission, called Sporadic-E ElectroDynamics, or SEED, opens its three-week launch window from Kwajalein Atoll in the Marshall Islands on Friday, June 13. The atmospheric features SEED is studying are known as Sporadic-E layers, […]
NASA’s CODEX Captures Unique Views of Sun’s Outer Atmosphere
Key Points: Scientists analyzing data from NASA’s CODEX (Coronal Diagnostic Experiment) investigation have successfully evaluated the instrument’s first images, revealing the speed and temperature of material flowing out from the Sun. These images, shared at a press event Tuesday at the American Astronomical Society meeting in Anchorage, Alaska, illustrate the Sun’s outer atmosphere, or corona, […]
Summer Students Scan the Radio Skies with SunRISE
Solar radio bursts, intense blasts of radio emission associated with solar flares, can wreak havoc on global navigation systems. Now, as part of the Ground Radio Lab campaign led by the University of Michigan and NASA’s SunRISE (Sun Radio Interferometer Space Experiment) mission, which is managed by the agency’s Jet Propulsion Laboratory in Southern California, […]
Space Cloud Watch Needs Your Photos of Night-Shining Clouds
Noctilucent or night-shining clouds are rare, high-altitude clouds that glow with a blue silvery hue at dusk or dawn when the sun shines on them from below the horizon. These ice clouds typically occur near the north and south poles but are increasingly being reported at mid- and low latitudes. Observing them helps scientists better […]

What NASA Is Learning from the Biggest Geomagnetic Storm in 20 Years
One year on, NASA scientists are still making huge discoveries about the largest geomagnetic storm to hit Earth in two decades, the Gannon storm. The findings are helping us better understand and prepare for the ways in which the Sun’s activity can affect us. One year ago today, representatives from NASA and about 30 other […]
