The NATIONAL ACADEMY OF SCIENCES will award the 2015 Public Welfare Medal to NEIL DEGRASSE TYSON(above). The honor is the academy's highest, given annually to those who "use science for the public good," according to the National Academy. Tyson wears many hats: He is an astrophysicist, cosmologist and science communicator. In 1995, he became the Frederick P. Rose Director of the Hayden Planetarium of the American Museum of Natural History. The author of 10 cosmology books, Tyson also hosts a radio show and podcast called "StarTalk Radio." He also served as executive editor and host for "Cosmos: A Spacetime Odyssey," a 2014 13-episode science documentary series. The 2014 version is a sequel to the original 1980 series, "Cosmos: A Personal Voyage," hosted by astronomer Carl Sagan.
