Young Earth was cocooned in a protective shield that magnetically deflected killer solar radiation 200 million years earlier than previously thought, a key factor that allowed life to take hold, according to a new study published this week in the journal Science. The research, based on analysis of ancient silicate crystals from South Africa, has implications for the search for life beyond Earth, which to date has focused on finding planets where liquid water can exist. The study by University of Rochester geophysicist John Tarduno and colleagues suggests that the ability of a planet to generate a large magnetic field also is important for developing life, as it provides a shield against high-energy radiation from the parent star.

But it wasn’t till the appearance of the ozone layer halfway through that life was able to come out of the oceans and colonize the land.
