According to NASA, changes in Earth’s magnetic field 540 million years ago corresponded with atmospheric oxygen shifts. This finding suggests that Earth’s deep interior may impact surface habitability. Scientists plan further research to trace these connections and their role in life’s origin.According to NASA, changes in Earth’s magnetic field 540 million years ago corresponded with atmospheric oxygen shifts.
