Its finely figured thin meniscus primary mirror, held in shape by a 156-element active optics system, regularly delivers impeccable seeing - a measure of the sharpness of a telescope’s image - to any of its five instruments at the Ritchey-Chrétien focus. Today, the fully commissioned telescope operates night in and night out at an elevation of about 7,800 feet (2,400 meters), some 40 miles (64 km) southeast of Flagstaff in Happy Jack, Arizona. The first-light gala celebration was almost exactly seven years later, featuring a marvelous keynote address by Neil Armstrong - his final public appearance before his death several weeks later. Groundbreaking for the DCT occurred on an especially hot day in July 2005. The research carried out with DCT proceeds as it would at any other professional telescope. In return for their contributions, they received naming rights and first right of refusal for use of images in educational broadcasts. These were gifts, not purchases: Discovery has no ownership of the telescope, nor any direction regarding the research it conducts. And Discovery, Hendricks, and his wife, Maureen, made gifts totaling $16 million toward the $53 million cost of the project. Discovery founder and former CEO John Hendricks has long been a member of the observatory’s Advisory Board. The modern bookend to the historic Clark telescope is Lowell’s 4.3-meter Discovery Channel Telescope (DCT), taking its name from the well-known media company. ![]() Perhaps the recently renamed Hubble-Lemaître Law should be further amended to the Hubble-Lemaître-Slipher Law? In a one-page notice in the Lowell Observatory Bulletin the following year, Slipher penned one of the greatest understatements in astronomical literature: “It might not be fruitless to observe some of the more promising spirals … Extension of the work to other objects promises results of fundamental importance.” His later observations with the Clark revealed the first cosmological redshifts - the stretching of light waves that’s a result of the expanding universe. To his surprise, he found Andromeda was hurtling toward our solar system at some 670,000 mph (1.1 million km/h). The first object he observed was the Andromeda Galaxy (M31). Slipher to observe so-called spiral nebulae with the Clark. It does not store any personal data.For instance: In 1912, Percival Lowell directed astronomer Vesto M.
