Weak spot in magnetic field may be caused by an ancient planet buried inside the Earth

There is a weak spot in the Earth’s magnetic field, and some scientists believe it may have been caused by the remnants of an ancient planet that impacted the Earth billions of years ago. The Earth has a protective geomagnetic field that shields the planet from deadly solar radiation. This field is generated by a process that … Continue reading Weak spot in magnetic field may be caused by an ancient planet buried inside the Earth

Research: Strange behavior of Earth’s magnetic field in the South Atlantic believed to be symptoms of an event that repeats every few million years

The Earth is protected from solar wind — a stream of charged particles from the sun — by its geomagnetic field. But this protective barrier is weak in certain areas, particularly south of the Atlantic Ocean. Called the South Atlantic Anomaly (SAA), this area makes it easier for solar wind and other cosmic rays to enter the … Continue reading Research: Strange behavior of Earth’s magnetic field in the South Atlantic believed to be symptoms of an event that repeats every few million years
