What is the story about?
What's Happening?
A team of geophysicists has identified a significant shift in mass deep within the Earth, near the core-mantle boundary. This discovery was made using data from NASA's GRACE satellites, which detected changes in the Earth's gravitational field. The shift, described as a 'geomagnetic jerk,' was first noticed in 2007 and is believed to be caused by changes in the mineral structure at the core-mantle boundary. The findings could provide new insights into the Earth's internal processes and the maintenance of its magnetic field.
Why It's Important?
Understanding shifts within the Earth's core is crucial for comprehending the planet's magnetic field, which protects against harmful solar radiation. This research could lead to advancements in predicting geomagnetic events that impact satellite operations and communication systems. The study also contributes to the broader understanding of Earth's geological processes, potentially influencing fields such as seismology and volcanology.
What's Next?
The research team plans to continue their investigation using data from the GRACE-FO mission, launched in 2018. This ongoing research aims to explore how changes at the core-mantle boundary affect core flow dynamics and the geomagnetic field. Further studies could reveal more about the Earth's deep interior and its influence on surface phenomena.
