For instance, the primary mirror is constructed from 91 hexagonal segments, which is less expensive than manufacturing a single large primary. The Hobby-Eberly Telescope Dark Energy Experiment, or HETDEX, is now training its full suite of instrumentation to reveal the nature and evolution of dark energy and plans to construct … The telescope has also been used to measure the rotation of individual galaxies. At 400,000 years, the universe became cool and thin enough that the ripples created during the Big Bang became frozen at a unique size. Working on IGRINS. McDonald is home to the Hobby-Eberly Telescope, one of the world's largest optical telescopes, with a 36-foot-wide (11 meter) mirror. The HPF, designed by a team of researchers from Penn State, is installed on the 10-meter Hobby-Eberly Telescope at McDonald Observatory in Texas. This research was supported by the National Science Foundation, Penn State, the Heising-Simons Foundation, the NASA Earth and Space Science Fellowship program, the Center for Exoplanets and Habitable Worlds at Penn State and the Research Corporation. [2], The physical main reflector mirror is larger than 9.2 meters; it is actually about 11 m by 9.8 m. However, the usable optical aperture at any given time is 9.2 m. The mirror itself is composed of 91 hexagonal segments, a segmented mirror design like the Keck telescopes. HPF was delivered to the 10m Hobby-Eberly Telescope at McDonald Observatory in late 2017 and started full science operations in late 2018. Three instruments are available to analyze the light from the targets. A target is tracked by moving the instruments at the focus of the telescope; this provides access to about 70–81% of the sky at its location and allows a single target to be tracked for up to two hours.

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. Every telescope with a primary mirror greater than about 8.5 meters in diameter uses this design, including the Hobby-Eberly Telescope at McDonald Observatory and the twin Keck telescopes in Hawaii. “It is exciting to see this first result of the HPF survey coming out. ("High-Resolution Fiber-Coupled Spectrograph of the Hobby-Eberly Telescope," SPIE Conf. There are not many options for making these at the size required for astronomical instruments, and in this case, the UNC lab was the only choice … and the price was right. [2][3] The telescope is named for former Texas Lieutenant-Governor Bill Hobby and for Robert E. Eberly, a Penn State benefactor. The telescope was upgraded for use in the Hobby–Eberly Telescope Dark Energy Experiment (HETDEX), which will provide the first observations to allow narrowing of the list of possible explanations for dark energy. Special telescope… The exciting new discovery, called G 9-40b, was validated using an astronomical spectrograph built by a Penn State team with the help of UNC-Chapel Hill’s Goodman Laboratory, led by Chris Clemens, stellar astrophysicist and senior associate dean for research and innovation in the College of Arts & Sciences. The details of the findings appear in the Astronomical Journal. Lua error in Module:Wikidata at line 446: attempt to index field 'wikibase' (a nil value).
