Its giant mirror was built for about one-seventh the cost of the other 10-meter telescope because it is constructed of many one-meter mirrors rigged to catch approximately as much light as one. The telescope was constructed for $13.9M over the period 1994-1997. A fixed elevation-axis design, based on the radio telescope at Arecibo, and an innovative system for tracking stars, contributed to an 80% reduction in initial costs compared to optical telescopes of similar size. It has already been a finalist for Discover Magazine’s Aviation and Aerospace Award because it does for $13.5 million much of what the Keck Telescope in Hawaii does for $100 million. Before his death in 1991, Harlan directed McDonald Observatory. Harlan’s great gift was not that he saw visions but that he could make others see the visions. It was designed specifically for spectroscopy, the decoding of light from stars and galaxies to study their properties. At any given time during observations, only a portion of the mirror is utilized. And remember that this was a case of first impression, a one of a kind, finely tuned instrument with a near-zero tolerance for mistakes. The interior of the George T. Abell Gallery, where visitors can learn about HET and view the telescope, is … But Harlan’s vision and Larry Ramsey’s idea would still be nice drawings without Frank Bash, the endlessly patient, tireless, doggedly persistent fundraiser and dealmaker who now directs McDonald Observatory, made the spectroscopic survey telescope a reality. The Hobby-Eberly Telescope, officially dedicated and open for business at the University of Texas at Austin’s McDonald Observatory in Fort Davis, is a scientific landmark, a milestone in engineering. This telescope is critical to a major study of dark energy, the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX).

Fowlkes engineering staff--policies and procedures, schedules, the problem report system, and more. The Wide Field Upgrade (WFU) is the first phase of the HETDEX retrofit. This telescope should help unlock the mysteries of black holes and dark matter, providing more clues to the origin of our universe. The deployment of the Visible Integral-field Replicable Unit Spectrograph (VIRUS), for the HETDEX project, will transform the HET into a powerful survey instrument like no other in astronomy, placing 35,000 fibers on the sky, each capable of collecting a distinct spectrum, with every exposure. Don’t build one 10-meter mirror. That is why the Hobby-Eberly Telescope has a dome covered with silver tape, which reflects more sunlight than its original white material. As darkness begins to fall, the Hobby-Eberly Telescope is … The Hobby-Eberly Telescope, the world’s third largest, sits high atop a hill in rural southwest Texas, one of the darkest places in America, all the better for stargazing.To get there, visitors follow Highway 118 to Dark Sky Drive — a winding, twisty road that leads up, up, left, right, until it arrives at the visitors’ center. The Hobby–Eberly Telescope (HET) is a 10-meter (30-foot) aperture telescope located at the McDonald Observatory in Davis Mountains, Texas. In the upper left, the Hobby-Eberly Telescope dome sits atop Mount Fowlkes. Facts and Figures; Faculty Honors and Awards; Science Rankings; Climate & Diversity Initiatives. He taught many of us astronomy on bright clear nights on Mount Locke, without the aid of any telescope. Hobby-Eberly Telescope Dark Energy Experiment survey begins full operations. With its 11-meter (433-inch) mirror, the Hobby-Eberly Telescope (HET) is one of the world's largest optical telescopes. It is located on Mt. other details? The flags of the four partner institutions fly with the U.S. flag outside the open dome. The HET saves money three ways.

Three years into its quest to reveal the nature of dark energy, the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) led by The University of Texas at Austin and involving Texas A&M University is on track to complete the largest map of the cosmos ever — a three-dimensional map of 2.5 million galaxies that will help astronomers understand how and why the expansion of the universe is speeding up over … The Hobby-Eberly Telescope at dusk. The Hobby-Eberly Telescope, built for a fraction of the cost of other giant telescopes, is dedicated at McDonald Observatory. He saw a 10-meter telescope for McDonald Observatory at a time when most Texans were totally preoccupied in figuring out where the oil boom had gone. The HET's 10 meter effective aperture places it among the world's five largest telescopes. It is also an excellent example of cost-effective collaboration. This telescope is a magnificent achievement. This makes it ideal in searching for planets around other stars, studying distant galaxies, exploding stars, black holes and more. The addition of 150 integral field spectrographs (VIRUS), mounted to the sides of the main framework, will give the HET the ability to map the expansion rate of the early universe, looking back in time billions of years, to measure how clusters of galaxies moved in relation to one another as the universe evolved. Scientific operations are expected in the spring of 1999. Required fields are marked *, A blog by former Texas Lieutenant Governor, Bill Hobby. Leadership. UNIVERSITY PARK, Pa. — Three years after its initial test observations, the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) is now training its full suite of instrumentation to reveal the nature and evolution of dark energy, the mysterious entity that is the primary constituent of the universe. And it was people who produced the Hobby-Eberly Telescope, starting with the visionary, Harlan Smith. Build lots of one-meter mirrors and mount them on a lattice in a way that will catch most of the light at a fraction of the cost. It took a world class project director to translate drawings and ideas into steel, glass and concrete on time and on budget.
