The world's largest telescope is nearing completion on a mountain top in Arizona. With the combined power of its two giant mirrors, the Large Binocular Telescope (LBT) will image the Universe in greater detail than NASA's Hubble Space Telescope. Andrew Luck-Baker talks to the astronomers who expect to see planets orbitting and being born around distant stars with the telescope. He also meets the technologists who designed and constructed the revolutionary observatory, and visits the spinning furnaces in which the 8.4 meter diameter mirrors were made. The LBT is a trail blazer for astronomical technologies in the next generation of super-massive telescopes. Producer: Andrew Luck-Baker.
