Invisible Universe Revealed

In 1990, Nasa launched one of the most ambitious experiments in the history of astronomy: the Hubble Space Telescope. Amazingly, when Hubble first sent images back to Earth, it seemed that the entire project was a massive failure; a one-millimetre 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, with scientists and engineers now able to outline 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.
