The black hole has approximately 59 percent of the mass of the bulge of this spiral galaxy (14 percent of the total stellar mass of the galaxy). 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. The planet, called G 9-40b, is about twice the size of the Earth, but likely closer in size to Neptune, and orbits its low mass host star, an M dwarf star, only 100 light years from Earth. Kepler detected the planet by observing a dip in the host star’s light as the planet crossed in front of — or transited — the star during its orbit, a trip completed every six Earth days. 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. [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 telescope mirrors are aligned within a fraction of a wavelength of visible light by actuators under each segment. HETDEX will study baryonic acoustic oscillations— "sound waves" from the first 400,000 years of the universe. The HRS is a single channel adaptation of the ESO UVES spectrometer as described by Tull. 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. Hobby-Eberly Telescope The 11-metre Hobby-Eberly Telescope is located in the Davis Mountains, Texas. 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.
