In the film, which is a part of the NOVA series Secrets of Lost Empires, NOVA brings together a team of Egyptologists, engineers, stonemasons, and timber framers to probe the mystery of how the ancients shaped, transported, and erected their elegant obelisks.

The program follows the efforts of two rival teams of astronomers as they search for exploding stars, map out gigantic cosmic patterns of galaxies, and grapple with the ultimate question: What is the fate of the universe?

This two-hour special, hosted by ABC "Nightline" correspondent Robert Krulwich, chronicles the race to capture one of the biggest prizes in scientific history: the complete letter-by-letter sequence of genetic information that defines human life -- the human genome.

A sequel to the most popular NOVA of all time, "Miracle of Life," the program once again uses the extraordinary microimagery of Swedish photographer Lennart Nilsson to track human development from embryo to newborn.

Experts struggle to save the City of Canals before it vanishes beneath the waves.

Rare lemurs and crocodiles with bizarre cave-dwelling behavior draw scientists to remote corner of Madagascar.

Scientists, meteorologists and storm chasers try to uncover the secrets of F5 tornadoes, the largest, most powerful and most dangerous on Earth.

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?

Astronomers are closing in on the proof they've sought for years that one of the most destructive objects in the universe—a supermassive black hole—lurks at the center of our own galaxy. Could it flare up and consume our entire galactic neighborhood? Join NOVA on a mind-bending investigation into one of the most bizarre corners of cosmological science: black hole research. From event horizon to singularity, the elusive secrets of supermassive black holes are revealed through stunning computer-generated imagery, including an extraordinary simulation of what it might look like to fall into the belly of such an all-devouring beast.

A magnificent trading vessel embarks on a royal expedition to a mysterious, treasure-laden land called Punt.
