An international team led by Chinese scientists has detected mysterious electromagnetic “space chorus” waves over 160,000 km from Earth – challenging previous beliefs about where these cosmic melodies occur! 🚀 Published in Nature, the discovery redefines our understanding of Earth’s magnetic interactions in space.
“It sounds like birds singing at dawn,” said Beihang University’s Liu Chengming, first author of the study, after converting the low-frequency waves into audible sound. 🌠 The team used data from NASA’s Magnetospheric Multiscale Mission to identify the phenomenon, caused by charged particles interacting with magnetic fields.
Why does this matter? These waves:
💥 Influence space weather that affects satellites
✨ Create dazzling polar auroras
🧠 Hold clues to high-energy particle acceleration
Collaborators from China, the U.S., and Sweden developed new theories to explain how these “nonlinear wave-particle interactions” occur far beyond Earth’s immediate magnetic zone. The breakthrough could improve space weather forecasts crucial for astronaut safety and global communications. 📡
