- Scientists discovered a mysterious shift in Earth's core-mantle boundary between 2006 and 2008 using satellite data.
- The shift was detected by the GRACE satellites, which measured changes in Earth's gravitational field.
- The change is believed to be due to denser rock formations near the core-mantle boundary.
- This discovery helps understand connections between Earth's layers, affecting earthquakes and the magnetic field.
- The GRACE satellites, originally used for water displacement studies, also detected deep Earth mass changes.
- A strange gravitational signal in 2007 off Africa's Atlantic coast was traced to deep Earth origins.
