Penn Science Café: “Remote Sensing: The Earth’s Increasingly Helpful Physician”


Tuesday, July 18, 6-7 p.m. 


World Cafe Live Upstairs, 3025 Walnut St., Philadelphia

In 1858, combining the inventions of the camera and the hot air balloon, French photographer and balloonist Gaspard-Felix Tournachon revealed the world from a perspective never seen before: above. As airplanes and then satellites took to the skies and photographic technology improved rapidly during the last century and a half, the black-and-white photos of the early days evolved into the detailed, beautiful and informative microwave, multispectral and hyperspectral “remote sensing” images of today. Such images now help detect oil spills, determine soil-moisture content, monitor vegetation growth, find mineral ores, observe ocean circulation, find ancient archeological sites, determine how much Earth shifted in an earthquake and so much more. These observations act, to some degree, as Earth’s physician, monitoring its health and helping to indicate potential paths to sustainability for Earth and its parasite, humans. This talk will explore some of these monitoring systems and what they’re telling us about Earth’s health today.

The talk is part of the Penn Science Café free public-lecture series presented by Penn Arts & Sciences and the Office of University Communications that takes science out of the lab for a night on the town. Dmochowski’s presentation will be followed by an audience Q&A. Café events are free and open to the public. Food and beverages will be available for purchase. Seating is limited. RSVPs are encouraged. To RSVP or for more information or directions: Gina Bryan at 215-898-8721 or
