Sun Stories

Key Points The largest solar storm in two decades hit Earth in May 2024. For several days, wave after wave of high-energy charged particles from the Sun rocked the planet. Brilliant auroras engulfed the skies, and some GPS communications were…

From Jan. 11 to 15, 2025, a bright comet surged through images from the ESA (European Space Agency) and NASA SOHO (Solar and Heliospheric Observatory) spacecraft. Called C/2024 G3 (ATLAS), the comet made its closest pass to the Sun, or perihelion, on…
UPDATE Feb. 11, 2025: The second rocket of the GIRAFF mission launched on Saturday, Feb. 8, at 11:35 p.m. Alaska Standard Time, through pulsating aurora over Venetie, Alaska. The principal investigator reported that all of the instruments looked healthy. The Black…

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…

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…

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…

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…

NASA researchers will present findings on Earth science, planetary science, and heliophysics at the upcoming American Geophysical Union (AGU) 2024 annual meeting in Washington, DC, beginning on Monday, Dec. 9. New NASA science results will be presented regarding the 2024…

NASA supercomputers are shedding light on what causes some of the Sun’s most complex behaviors. Using data from the suite of active Sun-watching spacecraft currently observing the star at the heart of our solar system, researchers can explore solar dynamics like never…

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…
