Tyler Nordgren is a Professor of Physics and Astronomy at the University of Redlands. For over a decade he has worked with the National Park Service to turn the national parks into the single largest source for public science and astronomy education in the world. His popular science book “Stars Above, Earth Below: A guide to astronomy in the national parks,” reveals what visitors to America’s national parks can observe in their dark night skies. For the upcoming 2017 eclipse he is helping the NPS prepare a campaign of “Go for the Sun, Stay for the Stars.” His newest book, “SUN MOON EARTH: The History of Solar Eclipses from Omens of Doom to Einstein and Exoplanets,” released in 2016 to excellent reviews, describes the vast array of social and scientific influences eclipses have had throughout history. Many of the color illustrations in this and his previous books include vintage-style “travel posters” he designed to help the public learn about and see the astronomical wonders in the sky – ranging from solar eclipses to the Milky Way and geologic features similar to those found on other worlds. In 2012, NASA’s Curiosity rover joined Spirit and Opportunity on Mars, each carrying sundials, or “Marsdials” which he helped design through his science and art. Dr. Nordgren gives public talks and multimedia programs across the country about what every American can expect to experience for this year’s All-American total solar eclipse. This will be his fourth total solar eclipse, his first, in 1979 at the age of nine, was the last total solar eclipse to be visible from the continental United States.
Dr. Jessie Christiansen is a staff scientist at the NASA Exoplanet Science Institute at Caltech. She searches for, studies, and catalogues extrasolar planets – planets orbiting other stars. Her main research focuses on using the thousands of exoplanets found by the NASA Kepler mission to determine how common planets similar to the Earth might be throughout the Galaxy, and preparing to do the same with TESS.
