'Saving Hubble' shows off the stars

As the avuncular host of "NOVA ScienceNOW" on PBS, Neil deGrasse Tyson is one of the few astrophysicists who is recognized outside of scientific circles. It's no accident that he has made so many appearances on "The Daily Show" and "The Colbert Report." He is witty and smart — but most importantly, he eschews jargon for regular talk. (His Twitter feed is pretty droll as well.)
