The Sun - Science@NASA
The Sun's gravity holds the solar system together, keeping everything – from the biggest planets to the smallest particles of debris – in its orbit. The connection and interactions between the Sun and Earth drive the seasons, ocean currents, weather, climate, radiation belts and auroras.
New Sun Missions to Help NASA Better Understand Earth-Sun …
Jul 26, 2023 · NASA has selected two science missions – the Multi-slit Solar Explorer (MUSE) and HelioSwarm – to help improve our understanding of the dynamics of the Sun, the Sun-Earth connection, and the constantly changing space environment.
NASA, NOAA to Provide Update on Progress of Solar Cycle
Oct 8, 2024 · When the Sun is most active, space weather events become more frequent. Solar activity, such as the storm in May 2024, has sparked displays of aurora and led to impacts on satellites and infrastructure in recent months. NASA works as a research arm of the nation’s space weather effort.

Oct 13, 2023 · 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…
NASA’s Heliophysics Experiment to Study Sun on European Mission
May 21, 2024 · NASA announced Tuesday it selected a new instrument to study the Sun and how it creates massive solar eruptions. The agency’s Joint EUV coronal Diagnostic Investigation, or JEDI, will capture images of the Sun in extreme ultraviolet light, a type of light invisible to our eyes but reveals many of the underlying mechanisms of the Sun’s activity.
NASA Enters the Solar Atmosphere for the First Time, Bringing …
Dec 14, 2021 · For the first time in history, a spacecraft has touched the Sun. NASA’s Parker Solar Probe has now flown through the Sun’s upper atmosphere – the corona – and sampled particles and magnetic fields there.
NASA’s NuSTAR Telescope Reveals Hidden Light Shows on the Sun
Feb 9, 2023 · The high-energy X-rays observed by NuSTAR appear at only a few locations in the Sun’s atmosphere. By contrast, Hinode’s XRT detects low-energy X-rays, and SDO’s AIA detects ultraviolet light – wavelengths that are emitted across the entire face of the Sun.

NASA’s Parker Solar Probe is studying our star from closer than any previous spacecraft. On Dec. 14, 2021, NASA announced that Parker had flown through the Sun’s upper atmosphere – the corona – the first time in history that a spacecraft had touched the Sun.
Solar Cycle 25 Is Here. NASA, NOAA Scientists Explain What That …
Sep 15, 2020 · The Solar Cycle 25 Prediction Panel, an international group of experts co-sponsored by NASA and NOAA, announced that solar minimum occurred in December 2019, marking the start of a new solar cycle. Because our Sun is so variable, it can take months after the fact to declare this event.
NASA’s Perseverance Captures ‘Googly Eye’ During Solar Eclipse
Oct 30, 2024 · The tiny, potato-shaped moon Phobos, one of two Martian moons, cast a silhouette as it passed in front of the Sun, creating an eye in Mars’ sky. From its perch on the western wall of Mars’ Jezero Crater, NASA’s Perseverance rover recently spied a “googly eye” peering down from space.
