NOVA scienceNOW is changing its format with a new season that tackles some of the biggest questions on people's minds in six specially themed new episodes. Hosted by engaging astrophysicist Neil deGrasse Tyson, the series will present sequences each week on a particular, thought-provoking topic--pondering who we are, how we got here and where things are going.
Premieres Wednesday, Jan. 19th on PBS (please check local listings). www.pbs.org/nova/sciencenow
