A recent study suggests that the primary components of life on Earth may have originated from solar eruptions. The research demonstrated that solar particles colliding with gases in Earth’s primitive atmosphere could produce amino acids and carboxylic acids, the fundamental elements of proteins and organic life.
in Greenbelt, Maryland, and coauthor of the new paper. “From the basic components of early Earth’s atmosphere, you can synthesize these complex organic molecules.” Energy from our young Sun – 4 billion years ago – aided in creating molecules in Earth’s atmosphere that allowed it to warm up enough to incubate life.

As long as the methane proportion was over 0.5%, the mixtures shot by protons produced detectable amounts of amino acids and carboxylic acids. But the spark discharges required about a 15% methane concentration before any amino acids formed at all. All else being equal, solar particles appear to be a more efficient energy source than lightning. But all else likely wasn’t equal, Airapetian suggested. Miller and Urey assumed that lightning was just as common at the time of the “warm little pond” as it is today. But lightning, which comes from thunderclouds formed by rising warm air, would have been rarer under a 30% dimmer Sun.
