NASA’s GNEISS Mission Will Map Electric Currents Behind the Aurora
NASA’s GNEISS mission will launch from Alaska in early 2026 to probe the electric currents that drive auroras. Two rockets will fly through glowing auroral arcs, releasing sub-payloads whose radio signals act like a CT scan. By mapping electron density and direction, scientists aim to improve space weather forecasting and better protect satellite...

Researchers Study Dark Matter Conversion Signals in Earth's Ionosphere
A study explored the potential of Earth's ionosphere as a medium to detect dark matter particles, specifically axions and dark photons. Researchers propose that these particles could convert into low-frequency radio waves within the ionosphere's plasma, creating detectable signals. By utilizing small, cost-effective dipole antennas, scientists aim ...

Scientists Uncover Invisible Ambipolar Electric Field Around Earth for First Time, New Study Reveals
Scientists have made a groundbreaking discovery by detecting and measuring the ambipolar electric field around Earth for the first time. This field, hypothesised over 60 years ago, was observed during the Endurance rocket mission launched by NASA in May 2022. The ambipolar field, located in the ionosphere at around 250 kilometres above Earth's surf...
