Story summary

A study using NASA-German GRACE satellites from 2006 to 2008 detected significant changes near Earth's core.
Researchers identified a gravitational anomaly indicating mass redistribution at depths of 2,700-2,900 km.
This anomaly suggests a mineral phase change affecting Earth's magnetic field.
The findings represent the first observation of deep mantle processes on human timescales.
Continued monitoring could enhance understanding of earthquakes and Earth's internal evolution.
