Doyle Peak
Doyle Peak is a peak in the Coconino National Forest, and the fourth-highest peak in the San Francisco Peaks of northern Arizona. It is the sixth-highest named point in the state of Arizona, with an elevation of . History of the Doyle Peak and adjacent Schultz Peak A small structure was built to house a telescope on nearby Schultz Peak by Lowell Observatory in 1927. It was referred to by some as a shepherd's cabin. The site was selected by V. M. Slipher, Director of Lowell Observatory, for a pair of bristlecone pine trees oriented in a north-south line. These were cut as supports for the polar axle of the telescope. The telescopes, a reflector and a reflector, were constructed by Stanley Sykes of Lowell Observatory. The cabin housing the telescope was constructed by a local stonemason. The structure had a corrugated metal roof that could be rolled off to expose the telescope for observations. The observing site also had a small dormitory partially cut into the hillside eas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Infrared
Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light. It is therefore invisible to the human eye. IR is generally understood to encompass wavelengths from around 1 millimeter (300 GHz) to the nominal red edge of the visible spectrum, around 700 nanometers (430 THz). Longer IR wavelengths (30 μm-100 μm) are sometimes included as part of the terahertz radiation range. Almost all black-body radiation from objects near room temperature is at infrared wavelengths. As a form of electromagnetic radiation, IR propagates energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon. It was long known that fires emit invisible heat; in 1681 the pioneering experimenter Edme Mariotte showed that glass, though transparent to sunlight, obstructed radiant heat. In 1800 the astronomer Sir William Herschel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stratovolcanoes Of The United States
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high-to-intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less-viscous mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as . Stratovolcanoes are sometimes called composite volcanoes because of their composite stratified structure, built up from sequential outpourings of erupted materials. They are among the most common types of volcanoes, in contrast to the less common shield volcano ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landforms Of Coconino County, Arizona
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features.

Ernst Öpik
Ernst Julius Öpik ( – 10 September 1985) was an Estonian astronomer and astrophysicist who spent the second half of his career (1948–1981) at the Armagh Observatory in Northern Ireland. Education Öpik was born in Kunda, Lääne-Viru, Governorate of Estonia, then a part of the Russian Empire. He went to the University of Moscow to specialize in the study of minor bodies, such as asteroids, comets, and meteors. He completed his doctorate at the University of Tartu. Astronomical work In 1916 Öpik published an article in the ''Astrophysical Journal'', in which he estimated the densities of visual binary stars. In his sample was ο2 Eridani B, a white dwarf star. Öpik determined its density as 25,000 times the density of the Sun but concluded that the result is impossible. In 1922, Ernst Öpik published a paper in which he estimated the distance of the Andromeda Galaxy. He determined the distance using a novel astrophysical method based on the observed rotational velocit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
