Earth's Core Waves Reveal New Paths for Planetary Exploration
Sydney, Australia (SPX) May 12, 2025 The detection of powerful seismic signals generated by winter storms in the North Atlantic Ocean, which travel through the Earth's core, could offer fresh insights into the study of our planet's interior and other celestial bodies, according to researchers at The Australian National University (ANU). ANU seismologists used two 50-by-50-kilometre spiral arrays in Australia to detect PKP waves-seismic core waves created by powerful cyclones in the North Atlantic that traverse the Earth's center and ... read more |
