Giant telescope's double vision
Lying beneath the clear skies of Arizona, the $120m (£55m) Large Binocular Telescope will allow astronomers to probe the Universe further back in time and in more detail than ever before.
"The LBT is a very exciting step forward for astronomy," said Professor Gerry Gilmore of the Institute of Astronomy at the University of Cambridge, UK.
"Not only is it big, but it is proving the practical implementation of some of the new technologies which will be critical for all next-generation large telescopes."
"Astronomers are looking for two things in a telescope," explained Dr John Hill of the University of Arizona and the technical director of LBT.
"They want a big collecting area so they can look at really faint objects far, far away; and they want high resolution images because they want sharp images of those faint fuzzy things far, far away."
