Tear down the middle school geology posters: We have an update. A team at Australian National University (ANU) has found evidence of a new fifth layer to the planet, an iron-nickel alloy ball in the inner core. The scientists found the hidden core by studying seismic waves that travel up to five times across the Earth's diameter – previous studies only looked at single bounces. The earthquake waves probed places near the center at angles that suggested a different crystalline structure deep inside.The ANU researchers also believe the innermost inner core hints at a major event in Earth's past that had a "significant" impact on the planet's heart. As researchers told The Washington Post, it could also help explain the formation of the Earth's magnetic field. The field plays a major role in supporting life as it shields the Earth from harmful radiation and keeps water from drifting into space.– Mat SmithThe Morning After isn’t just a newsletter – it’s also a daily podcast.
