In Antarctica, scientists have built the largest neutrino detector, which can catch cosmic neutrinos from billions of light-years away.

Neutrinos could help unlock one of the biggest mysteries in physics today.

Outnumbering atoms a billion to one, neutrinos are the universe’s most common yet most elusive and baffling particle. NOVA joins an international team of neutrino hunters as they try to capture an elusive fourth form of neutrino. Their results may force scientists to redraw their blueprint of the subatomic world, the Standard Model of physics, and change our understanding of how the universe works.

Colossal explosions shake a remote corner of the Siberian tundra, leaving behind massive craters. In Alaska, a huge lake erupts with bubbles of inflammable gas. Scientists are discovering that these mystifying phenomena add up to a ticking time bomb, as long-frozen permafrost melts and releases vast amounts of methane, a potent greenhouse gas. What are the implications of these dramatic developments in the Arctic? Scientists and local communities alike are struggling to grasp the scale of the methane threat and what it means for our climate future. (Premiered February 2, 2022)

In the Arctic, enormous releases of methane, a potent greenhouse gas, threaten the climate.
