Stellar irradiation received at the top of the atmosphere on Earth 2.7Ga ago (blue)30 and on TRAPPIST-1e (orange)29. Cross section per molecules of O2, O3 and H2O2 are represented in grey. Knowing O3 less abundant than O2, their photolysis shifting point is around 200nm, close to where the flux balance change between the Sun and TRAPPIST-1. -- astro-ph.EP
