Our Sun might be capturing headline after headline as its activity ramps up towards its solar maximum, but that’s nothing compared to what it was capable of when it was younger. Experts say it once sent superflares out into space every couple of days, but while that activity was once thought to prevent life, now some believe it may have ignited it on Earth.

00:00Our Sun might be capturing headline after headline as its activity ramps up towards its solar maximum,
00:09but that's nothing compared to what it was capable of when it was younger.
00:12Experts say it once sent super flares out into space every couple of days,
00:16but while that activity was once thought to prevent life, now some believe it may have ignited it on Earth.
00:21Using an atmospheric simulator, researchers sought to find out what would happen if primordial Earth,
00:26or our planet around four and a half billion years ago, was absolutely inundated with solar particles and lightning.
00:32Rather than the destruction of biological particles, what happened was the creation of amino acids and carboxylic acid,
00:38two things necessary for the genesis of proteins and therefore life.
00:42With the researchers writing about the findings, quote,
00:44This provides experimental evidence supporting the importance of solar energetic particle events in the young sun,
00:50as energy sources which were required for the synthesis of the biologically important molecules,
00:55deposited and accumulated in diverse aquatic geological settings of the early Earth.
00:59This comes after several re-evaluations of Earth's early atmosphere, which experts say was ripe with volcanic gases.
01:05But this particular mix containing molecular nitrogen, carbon dioxide, and water vapor sparked the necessary life-building particles,
01:12meaning we might have yet another clue about where else to look for life out in the cosmos.
01:18Good to see you from the beginning!
