Nova ScienceNow (styled
NOVA scienceNOW) is a
News magazine version of the long-running and venerable
PBS science program
Nova. Premiering on January 25, 2005, the series was originally hosted by
Robert Krulwich, who described it as an experiment in coverage of "breaking
science, science that's right out of the lab, science that sometimes bumps up against
politics,
art,
culture". At the beginning of season two,
Neil deGrasse Tyson replaced Krulwich as the show's host. Tyson announced he would leave the show and was replaced by
David Pogue beginning season 6.
