NOVA: Origins: Where Are the Aliens?
Overview
In "Origins: Where are the Aliens?," host astrophysicist Neil deGrasse Tyson explores such provocative questions as: would "ETs" resemble us or the creatures of science fiction? Are there "aliens" already amongst us on Planet Earth—brainy creatures whose intelligence is very different from our own? And are planets on which life can flourish rare or common in our universe?

Episode 2: Origins: How Life Began
"Origins: How Life Began," zeroes in on the mystery of exactly how it happened. Join the hunt for hardy microbes that flourish in the most unlikely places: inside rocks in a mine shaft two miles down, inside a cave dripping with acid as strong as a car battery's, and in noxious gas bubbles erupting from the Pacific ocean floor. The survival of these tough microorganisms suggests they may be related to the planet's first primitive life forms. Host astrophysicist Neil deGrasse Tyson deepens the search by investigating tantalizing and controversial chemical "signatures" of life inside three-billion-year-old rocks and meteorites found around the world.
Episode 4: Origins: Back to the Beginning
"Origins: Back to the Beginning" explores how the colossal, mind-boggling forces of the early universe made it possible for habitable worlds to emerge. The clues begin with a race among scientists to capture lingering echoes of the big bang's ferocious energy in a microwave "whisper" from deep space. The race pits underdog astronomer Tony Readhead and his improvised detector in the high Andes against NASA scientists and their state-of-the-art satellite probe. Host astrophysicist Neil deGrasse Tyson shares his excitement with viewers as computer animation of the big bang's echo emerges on the screen. It's as close as we can get to a "photograph" of the primordial universe. Here we glimpse the seeds from which all the galaxies, stars, and planets eventually grew.

Episode 1: Origins: Earth is Born
"Origins: Earth is Born" gives viewers a spectacular glimpse of the tumultuous first billion years of Planet Earth—a time of continuous catastrophe. Vivid animation lets viewers witness the traumatic birth of the moon from a titanic collision between Earth and an object believed to have been the size of Mars. Bombarded by meteors and comets, rocked by massive volcanic eruptions, and scoured by hot acid rain, the early Earth seems a highly improbable place for life to have taken root. Despite such violent beginnings, scientists have found new clues that life-giving water and oxygen appeared on our planet much earlier than previously thought.

Episode 8: Ancient Refuge in the Holy Land
Follow an expedition to a remote cave in the Judean desert, first excavated by the famed Israeli archeologist Yigael Yadin in 1960-61. Yadin uncovered a cache of ancient documents, human skulls, and artifacts that shed light on a legendary revolt by Jews against the Roman Empire in the year 132. The uprising, led by Jewish patriot Shimon Bar-Kokhba, is said to have resulted in the Roman slaughter of 580,000 Jews. NOVA explores the last refuge of one group of Bar-Kokhba's followers with an historian whose bold theories have rocked the world of biblical archeology.

Episode 10: The Boldest Hoax
For decades, a fossil skull discovered in Piltdown, England, was hailed as the missing link between apes and humans. Entire careers were built on its authenticity. Then in 1953, the awful truth came out: "Piltdown Man" was a fake! But who done it? In "The Boldest Hoax," NOVA gets to the bottom of the greatest scientific hoodwinking of all time.

Episode 12: The Viking Deception
Ever since its sensational unveiling by Yale University scholars in October 1965, the Vinland Map has been a lightning rod for passionate debate. Most reviews of the arguments, including NOVA's program, have focused on scientific tests designed to gauge the authenticity of the map's ink. The opinions of experts in cartography and historical manuscripts have commanded much less attention, yet from the outset scholars in these disciplines pointed out glaring anomalies in the case for the Vinland Map's authenticity.
Episode 13: Saving the National Treasures
