Excellent documentary, mind blowing and superbly narrated. EnjoyNarrated by Alec Baldwin.

Neanderthals dominated Europe for some 200,000 years until modern humans began moving into the region about 45,000 years ago. The two human species shared the Middle East for about 10,000 years between 45,000 to 35,000 years ago, but it's a mystery what happened during that period, and why Homo sapiens prevailed in the end.

Current archaeological evidence has placed the last known Neanderthal refuges on the Iberian Peninsula about 25,000 years ago, home to current-day Spain, Portugal and Gibraltar. Some of the very last remains found at Gibraltar indicate some of these last Neanderthals were hybrids part Neanderthal and part Homo sapien.

Enter the prehistoric world when dinosaurs ruled the Earth. See them hunt and battle. See them roam in massive herds. Go back in time and experience what dinosaur life was like.

This video shows how the asteroid that crashed in Yucatan some 65 million caused the mass extinction that wiped out the dinosaurs.

this is from the early 1990's. and it shows exactly how documentary programs were released , back then. Notice how they give a lot of information, within a shorter time span. That's because the programs were narrative documentaries. keyword: The Science channel, best of Science.

Deep space exploration is the term used for the exploration of deep space and which is usually described as being quite distant away from Earth, within or away from the solar system.

It is the branch of astronomy and space technology which is involved with exploring the distant regions of outer space. Physical exploration of space is conducted both by human spaceflights and by robotic spacecraft.

At present the furthest space probe mankind has constructed and launched from Earth is Voyager 1 which has only just reached[when?] the edge of our Solar System taking over 20 years to get there. Deep space exploration further than this is not yet possible due to current space engine technology available.

Some of the best candidates for future deep space engine technologies include anti-matter, nuclear power and beamed propulsion. The latter, beamed propulsion, appears to be the best candidate for deep space exploration presently available, since it uses known physics and known technology that is being developed for other purposes.

Earth's Force Field: The Earths magnetic field, the protector of all life on Earth is under constant attack from deadly cosmic radiation. This invisible shield that we live in is weakening in a region over the South Atlantic, leaving it exposed to potentially lethal radiation. Is the Earth losing its magnetic field and doomed to a fate similar to Mars? Many scientists believe the answer lies in paleomagnetic data, and that this weakening may be a precursor to a magnetic field reversal; scientists know Earth is long overdue. However, humans were not around when the last reversal took place, so what does this mean for life?

Go inside NASA's risky field trip to the red planet in this tense and dramatic behind-the-scenes chronicle of the $820 million Mars Exploration Rover (MER) project.
