A GEOLOGIST'S VIEW OF THE SOLAR SYSTEM

Incorporating breathtaking, full-color images taken by recent space probes, this program reveals some of the strangest terrains and most alien environments imaginable. You’ll learn about the “planetary twins” Earth and Venus—why one became a home for life and the other evolved into a nightmarish world with a pressure-cooker atmosphere, sulfuric-acid rain, and a barren landscape. You’ll see the great canyons and volcanoes of Mars, the diverse moons of Jupiter, and the beautiful worlds of the outer solar system. And in recognition of this August’s solar eclipse, visible in totality from southern Illinois and as a partial eclipse farther north in the state, you’ll discover why this dramatic celestial event is one of our best opportunities for understanding how other worlds in our solar system directly affect our own. This nontechnical talk appeals to adults and children of eleven years and up. Presented by Raymond Wiggers.
