A NASA-sponsored team at the University of Iowa (UI) is restoring and advancing the nation’s capability to make high-fidelity magnetic field measurements needed to investigate space weather that can impact our communication and power grids on Earth and our assets…
Recent airborne science flights to Greenland are improving NASA’s understanding of space weather by measuring radiation exposure to air travelers and validating global radiation maps used in flight path planning. This unique data also has value beyond the Earth as…
This story is also available in Spanish. A new NASA mission will capture images of Earth’s invisible “halo,” the faint light given off by our planet’s outermost atmospheric layer, the exosphere, as it morphs and changes in response to the…
Summary Space is a dangerous place — one that NASA continues to explore for the benefit of all. It’s filled with radiation and high-energy particles that can damage DNA and circuit boards alike. Yet life endures in our solar system…
Editor’s note: This story was updated to clarify the duration of the Sun’s quiet period beginning in 1645. It looked like the Sun was heading toward a historic lull in activity. That trend flipped in 2008, according to new research.…
Soon, there will be three new ways to study the Sun’s influence across the solar system with the launch of a trio of NASA and National Oceanic and Atmospheric Administration (NOAA) spacecraft. Expected to launch no earlier than Tuesday, Sept.…
Jupiter hosts the brightest and most spectacular auroras in the Solar System. Near its poles, these shimmering lights offer a glimpse into how the planet interacts with the solar wind and moons swept by Jupiter’s magnetic field. Unlike Earth’s northern…
Editor’s Note: This article was updated Aug. 20, 2025, to correct the number of years of training data used and the model accuracy. The original article said the model was trained on 14 years of Solar Dynamics Observatory data and surpassed…
For the fourth year in a row, the American Association of Physics Teachers, a collaborator on the NASA Heliophysics Education Activation Team (HEAT), selected eight new educators to serve as ambassadors for heliophysics education. Meeting in Boulder, CO, from July…
Astronaut Captures Rare Gigantic Jet from Space On July 3, 2025, NASA astronaut Nichole Ayers photographed an extraordinary sight from the International Space Station — a rare gigantic jet, a powerful electrical discharge shooting from the top of a thunderstorm…
