New research lends credence to an unorthodox retelling of the story of early Earth that was first proposed by a geophysicist at the Scripps Institution of Oceanography in La Jolla, California.
Molten silicate might solve a long-standing magnetic mystery
It was a lot more powerful than anyone believed.
Our planet is restless, and its poles are wandering.
Analysis finds that the planet’s protective shield was in place by at least 3.7 billion years ago, as early life arose.
Data from ESA’s Cluster mission has provided a recording of the eerie “song” that Earth sings when it is hit by a solar storm.
