The Core: Journey to the Center of the Earth (Enhanced DVD)
Product Description:
The core of planet Earth has always been difficult to reach and has taken many years to understand. While humans are still unable to reach the molten interior of the planet, scientists have learned much about the makeup of the Earth's interior and what the intense pressures and temperatures are like there. The core is located 4,000 miles inside the planet, and the pressure that the core is under is extreme. The center of the Earth is almost the same temperature as the sun, and seismologists have come up with many innovative ways to figure out what the center of the planet is like. Everything from the Hubble telescope to explosives have been used to add to our body of knowledge about the inside of our world.

Customer Reviews
The Earth’s core has long been inaccessible, which has made it difficult to research. The core is 4,000 miles beneath the surface and it has temperatures that are almost as hot as the Sun. In this program, scientists who have traveled deep beneath the surface of the Earth give us information about how the Earth’s core is studied and what they have found about how the Earth was formed.
Seismologists detonate explosives to contribute to the research. Strangely, a malfunctioning of the Hubble telescope gives experts a better understanding of the interior of the planet. Geophysicists in Tokyo recreate conditions that are similar to the core of the Earth and they also find evidence that the core is cooling faster than previously thought, which may have serious implications for life on the planet. Produced by the BBC. (50 minutes)
Segments in this video include:
Goddard Space Flight Center – Ken Label runs operations for unpiloted spacecraft. The Hubble telescope’s newest instruments are malfunctioning, and there is a concern that the system will be destroyed as a result.
NASA’s Bermuda Triangle – The potentially fatal spikes were occurring in South America as well as the south Atlantic ocean. Astronauts on previous space flights have reported similar events in the same region.
Magnetic field – The core of the planet is necessary for life. The magnetic field of the core protects the Earth from space radiation.
Lead, South Dakota – A deserted gold mine is shown which gives the sensation of going to the center of the Earth. Dr. Bill Roggenthen goes into the deepest laboratory in the United States which is located 1.5 kilometers below the surface. The pressure in the middle of the Earth is 3 million times greater than at the surface.
