- National Geographic reviews Jack Horner's research into juvenile dinosaurs. His evidence suggests that juvenile dinosaurs looked sufficiently different from adults that they have sometimes been mistaken for a separate species. The program examines specific changes that occurred as dinosaurs aged and speculates on why the changes were necessary.
- Scientists discuss the possibility of reverse-engineering the DNA of modern birds to recreate dinosaur species, instead of cloning fragments of dinosaur DNA extracted from amber and other ancient fossils.
- This film explores the most astonishing predictions of Jules Verne and H.G. Wells. Michio Kaku contributes.
- In 1958, in a sweltering, converted torpedo factory in Alexandria, Virginia, historian Gerhard L.

- In 1908 something felled millions of trees over 1000 square miles in Siberia, without leaving a trace. Many believe an asteroid was responsible. New evidence could at last solve the Tunguska mystery.
- Scientists reveal evidence of the existence of alien life. Detailed imaging of an underground ocean on a planetary moon and newly discovered extrasolar planets reveal what contacting alien life will be like. This is a serious scientific look at how will we meet ET.
