Physics and Astronomy Colloquium

Thursday, November 21st 2019
3:35 pm:
Speaker: Dimitar Sasselov, Harvard University
Subject: Stellar UV Light and the Origins of Life's Building Blocks

Evidence is emerging that mid-range UV light reaching the early Earth's surface might have played a central role in the synthesis and selection of life's molecular inventory. The process could be common to rocky Earth-size planets, and so spectroscopy of exoplanet atmospheres may help constrain it.
