The Moon is a stabilising force for Earth, enabling life to exist here. But it is receding and moving away faster each year. When it recedes 10% more, life as we know it will be wiped out.
From Hawaii's volcanoes to Greenland's glaciers to meteorites in Australia, teams of international scientists race to solve the mystery of how life first formed on Earth.
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.
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.
NASA satellite data and footage give new insight into the ecosystem of the Amazon rainforest, the plant life of the oceans as a barometer of the health of the seas, and the nature of violent storms.
Iceland's Eyjafjallajokull volcano erupted April 14, 2010, spewing aircraft-harming ash over most of Europe. It could cause Katla, its neighboring, larger volcano to erupt. NGC looks at Eyjafjallajokull before, during and after, explaining the science behind the chaos and the biggest disruption of air traffic since 9/11.
This program looks at the remarkable occurrence of the total solar eclipse over Easter Island on July 11, 2010. The program looks at the science of the sun as it is revealed via the eclipse phenomenon and then takes us "near live" to the actual event as the film will be aired domestically only a few hours after it takes place there.
