Hobby-Eberly Telescope Upgrade - HETDEX. Hobby-Eberly Telescope’s segmented primary mirror spans 11 meters (36 feet). [Martin Harris] World’s third-largest telescope will provide wide, deep view of distant galaxies The HETDEX project has two critical technological requirements. One is a set of instruments that can quickly gather and analyze the light from many distant galaxies at once. The other is a giant telescope that can see far into the universe, providing good views of galaxies that existed when the universe was only a few billion years old.
The first requirement is met by VIRUS, a set of about 150 spectrographs. Special Design While other large optical telescopes perform a variety of roles, the HET is designed to observe astronomical objects spectroscopically — in other words, to split light from an object into its component wavelengths.
