The W. M. Keck Observatory is an astronomical observatory with two telescopes at an elevation of 4,145 meters (13,600 ft) near the summit of Mauna Kea in the U.S. state of Hawaii. Both telescopes have 10 m (33 ft) aperture primary mirrors, and, when completed in 1993 (Keck I) and 1996 (Keck II), they were the largest optical reflecting ...
W. M. Keck Observatory at dawn, Mauna Kea, Hawaii The Keck II telescope on Mauna Kea, Hawaii projects a laser beam into the night sky to form an artificial guide star for adaptive optics. The galactic plane of the Milky Way is visible in the sky to the right of the image. The stars are trailed in this 3 minute fixed camera exposure due to the ...
HR 8799 is a roughly 30 million-year-old main-sequence star located 133.3 light-years (40.9 parsecs) away from Earth in the constellation of Pegasus.It has roughly 1.5 times the Sun's mass and 4.9 times its luminosity.
Then, the researchers used telescopes at the W. M. Keck and Gemini observatories in Hawaii to uncover more details about the ancient, dead galaxy where no new stars are being formed.

The Keck Observatory on the summit has a visitor gallery which is usually open between 10am and 4pm on weekdays, and free tours of the Subaru Telescope can be reserved on its web site, [10] but otherwise only observatory staff and visiting scientists are allowed inside observatory facilities.
It was discovered in August 2014, [3] deduced from analysis of the radial velocities of the parent star by the Eta-Earth Survey using HIRES at Keck Observatory.It has around 5.35 ± 0.75 Earth masses, [3] and is thought to be a Super-Earth with a diameter greater than that of the Earth.
