NOVA: " Invisible Universe Revealed "

Premieres Wednesday, April. 22 at 9pm on WGBH 2

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.
