...This one's a documentary, shot in IMAX 3-D. It's his cinematic take on the emerging science of astrobiology, the search for life in other worlds. Paradoxically, astrobiologists are equally fascinated with outer space and the ocean depths, where water superheated by magma from the Earth's crust spews from cracks called hydrothermal vents and sustains a bizarre menagerie of bacteria and other aquatic life...
...Titan is a chemical cousin of Earth, it's an Earth gone terribly wrong. The surface is etched with riverbeds and shorelines carved by the methane rains. The ground seems to be a thin, frozen crust over a smoother, softer layer. "Kind of a creme brulee consistency," says John Zarnecki, a principal science investigator. The atmosphere produces plenty of wind and weather, and there is even a flicker of a greenhouse effect, but with sunlight a thousand times dimmer than on Earth, it doesn't amount to much...
...docudrama Pompeii: The Last Day (Discovery, Jan. 30, 9 p.m. E.T.) did not set out to be a VSDM. That changed with the Indian Ocean tsunami, when entire habitations were, like the Roman city in 79 A.D., erased by a rumbling from beneath the earth's crust. A BBC co-production (as is Dirty War), Pompeii gives a scientific blow-by-blow of Vesuvius' eruption. More interestingly--and with more resonance today--it tries to tell the disaster's human story...
Scientists have known for some time about the 700-mile-long fault off the coast of Washington, Oregon and California, where a wayward slab of the earth's crust known as the Juan de Fuca plate is trying to slide under continental North America. What they didn't appreciate until quite recently was that the juncture where the two plates are locked together can snap violently like a giant spring, unleashing a tsunami as large and terrifying as the one that pummeled South Asia...
...cause of the carnage was a massive earthquake that trembled the earth's crust off the western coast of the Indonesian island of Sumatra, setting off through the oceans shock waves that were felt more than 3,000 miles away on the coast of East Africa, where at least 200 people died. Bustami, a fisherman from the Sumatran village of Bosun, is one who experienced the quake and tsunami and lived to tell about them. Sometime after 7:30 on the morning of Dec. 26, he says, he was on his boat just off the coast when he felt...
