From ourthis historic effort to create detailed three-dimensional maps beginning, Carnegie has been known for our extraordinaryof the entire sky. This latest generation will produce optical telescopes, which have transformed humankindsand infrared spectra of over 6 million objects, including understanding of the cosmos.
