Virtual Café Sci: Are dark skies in our future?
Mon., Oct. 5
7–9 pm

The night sky has been getting 2% brighter each year. Light pollution is the excessive, obtrusive light at night that prevents us from living under a sky bright with stars. 80% of the people in the United States live in cities and can't see the Milky Way. Artificial light at night adversely affects human health, and the environment can produce unsafe glare and raises our carbon footprint by wasting energy. To help Pittsburgh officials select shielded, low temperature LEDs for the city's 40,000 streetlights, Carnegie Mellon University architect Steve Quick and Café Sci speaker Diane Turnshek are monitoring skyglow from below and making a high-resolution nighttime map of the whole city from above with drones and airplanes. Learn how innovative science and technology can reverse the steady creep of light pollution, so we can once again view star-filled, dark night skies.
