Darkness at Night: Essential for Life

Smith College Professor of Astronomy James Lowenthal will lead us on a virtual tour of the night -- how the natural world comes alive, how humans and other diurnal creatures need darkness to thrive, how artificial light at night upsets ecosystems, and how the growing international Dark Sky movement is working to rein in light pollution and protect and bring back natural darkness at night. James Lowenthal, Mary Elizabeth Moses Professor and Chair of Astronomy at Smith College, uses large telescopes in space and on the ground to study the formation of galaxies in the early Universe, and also uses Smith's rooftop telescope with a team of students to study exoplanets orbiting stars in our Milky Way galaxy. He works locally, nationally, and internationally to protect the night sky from light pollution and satellite constellation Brought to you by Green Maynard and the Maynard Public Library.
