This is the incredible story of Trishna and Krishna, twin girls born joined at the head. Abandoned shortly after birth at an orphanage in Bangladesh, they had little chance of survival until they were saved and taken to Australia by an aid worker. With exclusive access to this extraordinary human and medical drama, NOVA's cameras were with Trishna and Krishna and their caregivers at each moment of their journey.

Take a spectacular trip to distant realms of our solar system to discover where secret forms of life may lie hidden. Combining the latest telescope images with dazzling animation, this program immerses audiences in the sights and sounds of alien worlds, while top astrobiologists explain how these places are changing how we think about the potential for life in our solar system. We used to think our neighboring planets and moons were fairly boring�mostly cold, dead rocks where life could never take hold. Today, however, the solar system looks wilder than we ever imagined.

NOVA meets a new breed of experts who are approaching "cold case" art mysteries as if they were crime scenes, determined to discover "who committed the art," and follows art sleuths as they deploy new techniques to combat the multi-billion dollar criminal market in stolen and fraudulent art.

During World War II, Hitler's scientists developed terrifying new weapons of mass destruction. Alarmed by rumors of advanced rockets and missiles, Allied intelligence recruited a team of brilliant minds from British universities and Hollywood studios to a country house near London. Here, they secretly pored over millions of air photos shot at great risk over German territory by specially converted, high-flying Spitfires. Peering at the photos through 3D stereoscopes, the team spotted telltale clues that revealed hidden Nazi rocket bases. The photos led to devastating Allied bombing raids that dealt crucial setbacks to the German rocket program and helped ensure the success of the D-Day landings. With 3D graphics that recreate exactly what the photo spies saw, NOVA tells the suspenseful, previously untold story of air photo intelligence that played a vital role in defeating the Nazis.

Get inside the mind of the genius behind one of the most unconventional weapons of WWII.In 1943 a squadron of Lancaster bombers staged one of the most audacious raids in history--destroying two gigantic dams in Germany's industrial heartland and cutting the water supply to arms factories--with a revolutionary bouncing bomb invented by British engineer Barnes Wallis. Wallis and the pilots of 617 Squadron--a lively mix of Britons, Australians, Americans, and Canadians--were hailed as heroes and dealt a mighty blow to the German war machine. Now, NOVA re-creates the extreme engineering challenges faced by Wallis and the pilots with the aid of spectacular experiments. Each represents a technical challenge that the Dambusters had to solve to make their mission a success. A crack team of experts--from dam engineers to explosives specialists--will step into the shoes of the Dambusters and attempt to overcome each obstacle in turn. They will adapt a vintage DC4 to carry a bomb the size of an oil drum; train to drop it from a dangerously low altitude in pitch darkness; get it to bounce over obstacles and onto the target; and finally, at a test site in Canada with a 1:6 scale model of one of the German dams, try to repeat history.
