Journaling: With its 11-meter (433-inch) mirror, the Hobby-Eberly Telescope (HET) is one of the world's largest optical telescopes. It was designed specifically for spectroscopy, the decoding of light from stars and galaxies to study their properties. This makes it ideal in searching for planets around other stars, studying distant galaxies, exploding stars, black holes and more.
Unlike most other telescopes, which tilt up and down in altitude, the HET's mirror is always tilted at 55 degrees above the horizon. However, the tracker mounted above the telescope moves in six directions, allowing the HET to study 70 percent of the visible sky. The 80-ton telescope rotates on a bed of air, using air cushions to lift and position the enormous instrument.
The telescope's mirror looks like a honeycomb. It's made up of 91 hexagonal mirrors that form a reflecting surface measuring 11 by 10 meters. The segments must be aligned exactly to form a perfect reflecting surface for good observations. HET is classified as a 10-meter telescope, making it the third largest optical telescope in the world.
The wide-field Hobby-Eberly Telescope focuses light into instruments including the Visible Integral-field Replicable Unit Spectrograph (VIRUS), the second generation Low Resolution Spectrograph (LRS2), the Habitable Zone Planet Finder and the second generation High Resolution Spectrograph (HRS2). The telescope is especially suited to conduct large survey projects using spectroscopy and take on the biggest challenges in astronomy today: unraveling the mystery of dark energy, probing distant galaxies and black holes, discovering and characterizing planets around other stars and much more.
