  NOVA revolves around a simple premise: the world of science is exciting! For NOVA viewers, science means adventure and exploration—because from ants to aliens, this weekly documentary series probes the far reaches of earth, sea and stars. NOVA proves that science is neither secret lore nor sacred ritual but rather, at its heart, a lifelong journey of discovery.
