PBS's NOVA Announces Spring/Summer Premieres

Below are NOVA's upcoming premieres on PBS for spring and summer 2015:

NOVA PREMIERES ON PBS

"THE GREAT MATH MYSTERY"
Wednesday, April 15, 2015 at 9pm ET/8c on PBS
NOVA leads viewers on a mathematical mystery tour?a provocative exploration of math?s astonishing power across the centuries. We discover math?s signature in the swirl of a nautilus shell, the whirlpool of a galaxy, and the spiral in the center of a sunflower. Math was essential to everything from the first wireless radio transmissions to the prediction and discovery of the Higgs boson, and the successful landing of rovers on Mars. But where does math get its power? Astrophysicist and writer Mario Livio, along with a colorful cast of mathematicians, physicists, and engineers, follow math from Pythagoras to Einstein and beyond, all leading to the ultimate riddle: Is math an invention or a discovery? Humankind?s clever trick, or the language of the universe? "The Great Math Mystery" is a show for everyone; whether we think we?re good with numbers or not, we all use math in our daily lives. "The Great Math Mystery" sheds fascinating light on how math works in our brains and ponders the ultimate mystery of why it works so well when decoding the universe.

"INVISIBLE UNIVERSE REVEALED"
Wednesday, April 22, 2015 at 9pm ET/8c on PBS
Twenty-five years ago, NASA launched one of the most ambitious experiments in the history of astronomy: the Hubble Space Telescope. In honor of Hubble?s landmark anniversary, NOVA tells the remarkable story of the telescope that forever changed our understanding of the cosmos and our place in it. But amazingly, when the telescope first sent images back to earth, it seemed that the entire project was a massive failure; a one-millimeter engineering blunder had turned the billion-dollar telescope into an object of ridicule. It fell to five heroic astronauts in a daring mission to return Hubble to the cutting edge of science. NOVA hears from the scientists and engineers on the front line who tell the amazing Hubble story as never before. This single telescope has helped astronomers pinpoint the age of the universe, revealed the birthplace of stars and planets, advanced our understanding of dark energy and cosmic expansion, and uncovered black holes lurking at the heart of galaxies. For more than a generation, Hubble?s stunning images have brought the beauty of the heavens to millions, revealing a cosmos richer and more wondrous than we ever imagined. Join NOVA for the story of this magnificent machine and its astonishing discoveries.

"NAZI ATTACK ON AMERICA" (NOVA/National Geographic special)
Wednesday, May 6, 2015 at 9pm ET/8c on PBS
Long before 9/11, a far deadlier, little known attack struck our shores, lasting three and a half years and claiming 5,000 lives?an attack launched from the ocean depths. Now, famed undersea explorer Bob Ballard, discoverer of the Titanic, investigates the wreck of one of the attack craft, a German submarine that lies at the bottom of the Gulf just a few miles off New Orleans. U-166 was part of Operation Drumbeat, a highly successful U-boat operation that caught East Coast cities and shipping almost completely unprepared. With state-of-the-art survey gear, Ballard probes the wreck and unravels a dramatic mystery in the official story of the sub?s sinking. "Nazi Attack on America" also explores other sunken relics of Operation Drumbeat. And NOVA takes on the ultimate question: why didn?t the Germans press home the heavy losses Drumbeat inflicted on Allied shipping and ultimately win the Battle of the Atlantic?a victory that might have turned the tide of World War II?

"LETHAL SEAS"
Wednesday, May 13, 2015 at 9pm ET/8c on PBS
A deadly recipe is brewing that threatens the survival of countless creatures throughout Earth?s oceans. For years, we've known that the oceans absorb about a quarter of the carbon dioxide in our atmosphere. But with carbon emissions sharply rising, this silent killer is entering our seas at a staggering rate?raising the ocean?s acidity. As a result, the skeletons and shells of marine creatures that are the foundation of the web of life are dissolving away. NOVA follows the adventures of scientists seeking solutions and making breakthrough discoveries, including a unique coral garden in Papua New Guinea that offers a glimpse of what the seas could be like a half-century from now. Can our experts crack the code of a rapidly changing ocean?before it's too late?

"PLUTO FLYBY" (w.t.)
Wednesday, July 15, 2015 at 9pm ET/8c on PBS
NOVA captures New Horizons' historic flyby of Pluto, the culmination of the spacecraft's nine-year, three billion mile journey to reveal the first-ever detailed images of this strange, icy world at the very edge of our solar system.

"FUKUSHIMA" (w.t.)
Wednesday, July 29, 2015 at 9pm ET/8c on PBS
Four years after one of history?s worst nuclear accidents, NOVA reveals the minute-by-minute story of the Fukushima nuclear crisis and its ongoing aftermath, told by the brave workers who stayed behind as an earthquake and tsunami crippled the plant.
