NASA is turning up the heat in solar science with the launch of the Surya Heliophysics Foundational Model, an artificial intelligence (AI) model trained on 14 years of observations from NASA’s Solar Dynamics Observatory. Developed by NASA in partnership with IBM and others, Surya uses advances in AI to analyze vast amounts of solar data, … Read more
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. On May 10, 2024, the first G5 or “severe” geomagnetic storm … Read more
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 before. The animation shows the strength of the turbulent motions of the Sun’s inner layers … Read more
NASA has awarded a contract extension to Stanford University, California, to continue the mission and services for the Helioseismic and Magnetic Imager (HMI) instrument on the agency’s Solar Dynamics Observatory (SDO).

Guessing your age might be a popular carnival game, but for astronomers it’s a real challenge to determine the ages of stars. Once a star like our Sun has settled into steady nuclear fusion, or the mature phase of its life, it changes little for billions of years. One exception to that rule is the … Read more
