In May 2018, Kīlauea volcano erupted, obliterating neighborhoods with devastating force and uprooting thousands of residents. It is Hawai'i's most destructive volcanic eruption in generations. How can one of the most beautiful places on Earth suddenly transform into a roaring inferno, sputtering molten lava and bombs of volcanic rock the size of refrigerators? NOVA joins scientists and residents on a breathtaking journey to investigate Kīlauea's recent spike in activity. Along the way, some of Hawai'i's biggest secrets are revealed.
The ancient ancestors of today's Maya people thrived in large, sophisticted cities across Central America for centuries. Why, around 750 CE, did they begin to abandon many of their major cities? Archaeologists investigate dramatic new evidence of the catastrophic droughts and survival and resilience of the Mayan people, whose traditions and creativity continue to enrich today's world.
Einstein called it "spooky action at a distance," but today, quantum entanglement is poised to revolutionize technology from computers to cryptography. Physicists have gradually become convinced that the phenomenon — two subatomic particles that mirror changes in each other instantaneously over any distance — is real. But a few doubts remain. NOVA follows a ground-breaking experiment in the Canary Islands to use quasars at opposite ends of the universe to once and for all settle the remaining questions.
