Investigate news and newsmakers Tuesday nights on Arizona PBS.
There are still parts of our planet yet to be discovered. Explorer and naturalist Steve Backshall pursues incredible journeys and world firsts — unclimbed peaks, unexplored cave systems and uncharted landscapes — setting foot where no human has been before. "Expedition with Steve Backshall" comes to Arizona PBS Wednesdays at 9 p.m. starting Jan. 15.
"Nova" explores new discoveries and how we have come this far on Wednesdays at 8 p.m. on Arizona PBS.
