Controversial observations of long-term changes in the ionosphere appear to be explained by the Sun’s 11-year cycle of activity, not human greenhouse gas emissions.Read More »Space Science & Space Physics
Data from the Cassini spacecraft show that the cusp regions of Saturn’s magnetic field—where it connects to the Sun’s magnetic field—have similarities to Earth’s and also intriguing differences.Read More »Space Science & Space Physics
A new study finds that the ionospheric anomaly over the Weddell Sea is likely influenced by proximity to auroral energy input, rather than by tilting magnetic fields.Read More »Space Science & Space Physics
After geomagnetic storms, Earth’s corona abruptly increases in hydrogen density. For the first time, serendipitous observations have allowed researchers to investigate why.Read More »Space Science & Space Physics
Scientists demonstrate the capabilities and limitations of the mathematical model used to calculate solar irradiance using measurements from NASA’s Mars Atmosphere and Volatile Evolution (MAVEN).Read More »
