From volcanoes to space exploration, “Nova” answering the big questions of today and tomorrow every Wednesday at 8 p.m. on Arizona PBS.
“Saving the Dead Sea” — The “sea of salt” is biblical in history and significance, but it could be dying. After more than a decade of research and debate, scientists, engineers and political leaders have come up with a daring plan, one that could not only save the sea but help bring stability to a region rife with conflict. NOVA follows this unprecedented endeavor — perhaps the world’s largest water chemistry experiment ever — as scientists and engineers race to save the Dead Sea and help bring water to one of the driest regions on Earth. Watch via Passport.
“Inside the Megafire” — From the front line of the Camp Fire, the deadliest wildfire in California history, NOVA tells the stories of residents who had to flee for their lives during the 2018 fire season. Scientists racing to understand what’s behind the rise of record-breaking megafires across the American West take to the forest and even a fire lab in search of answers. They investigate how forestry practices, climate change, and the physics of fire itself play a role in the dramatic increase in wildfires in recent decades. Watch via Passport.
“First Horse Warriors” — Horse riding played a key role in human expansion and civilization. But when and how did people first master these animals? Scientists use archaeology and genetics to uncover clues about the first horse riders and how they shaped the world. Watch via Passport.
“Lost Viking Army” — Bioarchaeologists investigate a ninth-century mass grave in a rural English village. Will the remains unlock the mystery of the “Great Heathen Army,” a legendary Viking fighting force that once invaded England? Watch online.
“Inside Einstein’s Mind” — Retrace Einstein’s thought experiments as NOVA reveals the simple but powerful ideas that reshaped our understanding of gravity, illuminating the theory of general relativity-and Einstein’s brilliance-as never before. Watch online.
“Asteroid: Doomsday or Payday?” — The asteroid that exploded in the skies over Siberia injuring more than 1,000 and damaging buildings in six cities was a shocking reminder that Earth is a target in a cosmic shooting range. From the width of a football field to the size of a small city, the space rocks called asteroids have the potential to be killers. Watch online.
“First Man on the Moon” — NOVA presents an intimate portrait of Neil Armstrong, the first person to set foot on the moon, through interviews with Armstrong’s family and friends. The film reveals his achievements as a Navy combat veteran and pioneer of high-speed flight. NOVA revisits the final moments of the Apollo 11 landing, when Armstrong brought the Eagle down safely with seconds to spare, but he regretted that he got so much credit for the team effort that the lunar landing represented.
