Green will discuss how we continue to use shadow techniques to uncover new science and will provide spectacular examples from recent events. Eclipses are defined by the Oxford Dictionary as the obscuring of the light from one celestial body by the passage of another between it and the observer. It should be noted that this is nearly the same definition that describes occultations and transits. These phenomena create shadows that are regularly observed. But these shadows also allow scientists to do amazing new things, from finding new rings at Saturn to new planets orbiting other far away stars.

Green is a speaker in the 2018 NASA Goddard Lectures Series at the Library of Congress. Earlier talks in the NASA series included the topics of space weather, improved global water security and sustainability, how Mars has changed over time, NASA's Hubble Space Telescope and the upcoming James Webb Space Telescope.

The Library of Congress is the nation's oldest federal cultural institution and the largest library in the world and holds nearly 151.8 million items in various languages, disciplines and formats. The library serves Congress and the nation both on-site in its reading rooms on Capitol Hill.
