Missions to Jupiter: Rare, Wonderful, and Huge

August 9, 2018 @ 6:30 PM - 7:30 PM

This evening event is devoted to the wonders of planet Jupiter. DeKalb Public Library welcomes Bill Higgins, one of NASA’s Solar System Ambassadors, to elaborate on the discoveries that have emerged from NASA’s missions to Jupiter.  This cold, majestic planet has been visited by several spacecraft: Pioneer, Voyager, Galileo, and more.

Come learn how each mission has investigated old questions about Jupiter  (What is it made of? How does it generate heat?), added new discoveries  (Jupiter has rings! Some of its moons may support life!), and suggested new questions for the next mission to answer (Will the Giant Red Spot eventually disappear? Does Jupiter have a solid or liquid core?).

Learn also about the mysteries that still remain.  In 2016, Juno, a new NASA spacecraft, arrived at Jupiter. Juno’s mission is to orbit the giant planet, studying its powerful magnetic field, its intense radiation belts, and the intricate interplay of particles and energies surging through nearby space. It’s in orbit right now, learning more about Jupiter every day. Jupiter will be bright in the southwestern sky as you leave the library after the talk!

As a volunteer Solar System Ambassador for NASA, Bill Higgins has given talks to the public for over 20 years.  He is a radiation safety physicist at Fermilab, where has worked since 1978. Long fascinated with the outer planets, he witnessed the Voyager 2 encounter with Neptune in 1989 and the New Horizons encounter with Pluto in 2015.

This FREE program is intended for ages 10 and up. Registration is not required.
