A planet’s magnetic field usually protects its atmosphere from being blown away by its star. But new research suggests Mars’s weak magnetic field may have helped its atmosphere escape.Read More »
The transition of space weather science from research to operations needs a framework with both good science and a good dialogue with end users. Read More »Space Science & Space Physics
The gaseous atmospheres of giant planets may evaporate and accrete onto the dense surfaces of white dwarfs, providing astronomers a new way to detect hidden exoplanets.Read More »Planetary Sciences
When the lander MASCOT, carried by Hayabusa2, touched down on asteroid Ryugu, it did not detect a magnetic field, even though meteorites that are spectroscopically similar to Ryugu have trace of one.Read More »Space Science & Space Physics
Better forecasts of space-weather driven changes in thermospheric density are urgently needed to ensure safe management of the rapidly growing volume of space traffic in low Earth orbit.Read More »Space Science & Space Physics
Spacecraft sometimes produce a form of electrical self-interference as they zip through plasmas in space—a previously unreported effect that may be lurking in old data sets.Read More »Space Science & Space Physics
A new analysis of spacecraft data collected near the tip of Earth’s magnetotail sheds light on how geomagnetic activity affects the motion of electrons in this region.Read More »Space Science & Space Physics
Not to be outdone by the discovery of STEVE sub-auroral emissions last year, citizen scientists across Scandinavia reveal dune-shaped optical features, a new atmospheric phenomenon.Read More »
Measurements of very-low frequency radio signal phase and amplitude can detect upper atmosphere changes caused by solar flares, enabling us to monitor flare occurrence and intensity.Read More »
