The Sun's Role in the Origin of Life on Earth.
Superflares from a hyperactive young sun may have sparked life on Earth by firing charged particles found in the solar wind at a concoction of gases present in Earth's early atmosphere, forming significant quantities of amino acids and carboxylic acids — the building blocks for proteins and all organic life. A new study has used a particle accelerator to find that cosmic rays from fiercely energetic superflares could have provided the necessary jump-start for life on Earth.
