World Magnetic Model 2025 Released | News | National Centers …
Dec 17, 2024 · The latest version of the World Magnetic Model (WMM), one of the key tools developed to model the change in Earth's magnetic field, has been released. The WMM is a spherical harmonic model of the Earth’s main magnetic field and its slow temporal change.
Earth’s magnetic field has a dent, and NASA is watching closely
6 days ago · Earth’s magnetic field is like an invisible shield that surrounds our planet, generated by the movement of molten metal in Earth’s outer core. This movement creates electric currents, which in turn produce a magnetic field. The field has two main poles – north and south – just like a magnet, and it stretches far into space.
NASA Is Tracking a Huge, Growing Anomaly in Earth's Magnetic Field
Mar 23, 2023 · NASA is actively monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies above the planet, stretching out between South America and southwest Africa.
The position of the magnetic north pole is officially changing.
On Dec. 17, the National Centers for Environmental Information (NCEI) and the British Geological Survey (BGS) released an updated version of the World Magnetic Model, a prediction for how...

Nov 6, 2024 · A trio of physicists, two with Coventry University, in the U.K., and the third with Laboratoire National des Champs Magnétiques Intenses, in France, has demonstrated how Earth's magnetic...
NASA's LEXI will provide X-ray vision of Earth's magnetosphere
6 days ago · 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.
LEXI will watch Earth’s magnetosphere 'breathing' from the moon
3 days ago · LEXI will capture the first global images of Earth’s magnetic field. The journey kickstarts at NASA’s Kennedy Space Center in Florida, with Firefly Aerospace’s Blue Ghost Lander hosting LEXI. Lunar landing with an earthly objective. Upon successful landing, LEXI will jolt into action, focusing its gaze back towards Earth.
