Early magnetic field around Earth was even stronger than previously believed
The scientists from the University of Rochester found that the magnetic field initially formed around the earth was stronger than what the previous studies declared. The revelation in their new study has helped other scientists to draw conclusions regarding the sustainability of the magnetic field around the earth and to determine if the other planets in the solar system with such conditions can harbor life or not.
John Tarduno, William R. Kenan, Jr., Professor of Earth and Environmental Sciences and Dean of Research for Arts, Sciences, and Engineering at Rochester, said, “This research is telling us something about the formation of a habitable planet. One of the questions we want to answer is why Earth evolved as it did, and this gives us even more evidence that the magnetic shielding was recorded very early on the planet.”
Tarduno said, “This early magnetic field was significant because it shielded the atmosphere and water removal from the early Earth when solar winds were most intense,” Tarduno says. “The mechanism of field generation is almost certainly important for other bodies like other planets and exoplanets.”
