Voyager Leaves The Solar System, A CU Boulder Scientist Looks Back

In 1977, NASA launched two space probes to explore deep space and expand our view of the solar system. 40 years later, Voyager 1 and 2 are still sending back images to the amazement of scientists -- including University of Colorado Boulder’s Fran Bagenal. She’s a professor at CU Boulder’s Laboratory for Atmospheric and Space Physics… For Bagenal, the planets themselves aren’t nearly as fascinating as their moons.
