NASA Scientists Find Ties Between Earth's Oxygen and Magnetic Field
The solar wind flows around Earth's magnetic field. A new NASA study suggests that the amount of oxygen in the atmosphere and strength of the magnetic field have been correlated for more than half a billion years. NASA's Goddard Space Flight Center/Conceptual Image Laboratory For 540 million years, the ebb and flow in the strength of Earth's magnetic field has correlated with fluctuations in atmospheric oxygen, according to a newly released analysis by NASA scientists. The research suggests tha
