Big Picture Science

While the Kepler spacecraft hunts for habitable planets beyond the solar system, we’ve let one of our own planets slip away! Find out why Pluto’s demotion to dwarf status created a public uproar as astrophysicist Neil deGrasse Tyson reads us his hate mail. From third-graders! Also, how we might find Earth-like planets… the possibility of life on Saturn’s moon Titan… and TED Prize winner Jill Tarter’s vision for finding E.T. And, the man who made it all possible: 400 years of Galileo and the telescope. Part of our series for the International Year of Astronomy.
