Remote Sensing: The Earth's Increasingly Helpful Physician

Penn Science Cafe

In 1858, by combining the inventions of the camera and the hot air balloon, French photographer and balloonist Gaspar Felix Tournachon revealed the world from a perspective never seen before by the human eye: from up above. As airplanes and 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.

Dmochowski will talk about how these images can act as the Earth’s “physician,” indicating what the planet’s health is today by detecting oil spills, determining soil-moisture content, monitoring vegetation growth, observing ocean circulation, and much more.

Expert faculty from the University of Pennsylvania shed light on their research at the Penn Science Café. It's an evening of engaging, stimulating conversation, with a Q&A session following each talk.

Presented by Penn Arts and Sciences in partnership with the Office of University Communications, Penn Café events are free and open to the public, but RSVPs are encouraged. For more information or directions, contact Gina Bryan at 215-898-8721 or email at

Menu items are available for purchase. Happy Hour pricing from 4–6 p.m.
