NASA Solar Observatory Sees Coronal Loops Flicker Before Big Flares

For decades, scientists have tried in vain to accurately predict solar flares — intense bursts of light on the Sun that can send a flurry of charged particles into the solar system. Now, using NASA’s Solar Dynamics Observatory, one team has identified flickering loops in the solar atmosphere, or corona, that seem to signal when […]

NASA’s LEXI Will Provide X-Ray Vision of Earth’s Magnetosphere

A NASA X-ray imager is heading to the Moon as part of NASA’s Artemis campaign, where it will capture the first global images of the magnetic field that shields Earth from solar radiation. The Lunar Environment Heliospheric X-ray Imager, or LEXI, instrument is one of 10 payloads aboard the next lunar delivery through NASA’s CLPS (Commercial […]

NASA’s Parker Solar Probe Makes History With Closest Pass to Sun

Operations teams have confirmed NASA’s mission to “touch” the Sun survived its record-breaking closest approach to the solar surface on Dec. 24, 2024. Breaking its previous record by flying just 3.8 million miles above the surface of the Sun, NASA’s Parker Solar Probe hurtled through the solar atmosphere at a blazing 430,000 miles per hour […]

Scientists Share Early Results from NASA’s Solar Eclipse Experiments 

On April 8, 2024, a total solar eclipse swept across North America, from the western shores of Mexico, through the United States, and into northeastern Canada. For the eclipse, NASA helped fund numerous research projects and called upon citizen scientists in support of NASA’s goal to understand how our home planet is affected by the […]

5 Surprising NASA Heliophysics Discoveries Not Related to the Sun

With NASA’s fleet of heliophysics spacecraft, scientists monitor our Sun and investigate its influences throughout the solar system. However, the fleet’s constant watch and often-unique perspectives sometimes create opportunities to make discoveries that no one expected, helping us to solve mysteries about of the solar system and beyond.

Hurricane Helene’s Gravity Waves Revealed by NASA’s AWE

On Sept. 26, 2024, Hurricane Helene slammed into the Gulf Coast of Florida, inducing storm surges and widespread impacts on communities in its path. At the same time, NASA’s Atmospheric Waves Experiment, or AWE, recorded enormous swells in the atmosphere that the hurricane produced roughly 55 miles above the ground.

Final Venus Flyby for NASA’s Parker Solar Probe Queues Closest Sun Pass

On Wednesday, Nov. 6, 2024, NASA’s Parker Solar Probe will complete its final Venus gravity assist maneuver, passing within 233 miles (376 km) of Venus’ surface. The flyby will adjust Parker’s trajectory into its final orbital configuration, bringing the spacecraft to within an unprecedented 3.86 million miles of the solar surface on Dec.

30 Years On, NASA’s Wind Is a Windfall for Studying our Neighborhood in Space

Picture it: 1994. The first World Wide Web conference took place in Geneva, the first Chunnel train traveled under the English Channel, and just three years after the end of the Cold War, the first Russian instrument on a U.S. spacecraft launched into deep space from Cape Canaveral. The mission to study the solar wind, […]
