BLAST (telescope)
The Balloon-borne Large Aperture Submillimeter Telescope (BLAST) is a submillimeter telescope that hangs from a high-altitude balloon. It has a 2-meter primary mirror that directs light into bolometer arrays operating at 250, 350, and 500 µm. These arrays were developed for the SPIRE instrument on the Herschel Space Observatory. The project is carried out by a multi-university consortium headed by the University of Pennsylvania and which also includes University of Toronto, Brown University, the University of Miami, the University of British Columbia, JPL, INAOE, and Cardiff University. The third flight of BLAST in Antarctica was a scientific success, but much of telescope was destroyed after landing. It has been rebuilt for a flight from Antarctica in the 2010-11 austral summer. This most recent flight of BLAST (aka BLAST-Pol) has a polarimeter to observe the polarized light from star forming cores. The light is polarized due to magnetic fields. It is thought that the m ...

Submillimetre Astronomy
Submillimetre astronomy or submillimeter astronomy (see spelling differences) is the branch of observational astronomy that is conducted at submillimetre wavelengths (i.e., terahertz radiation) of the electromagnetic spectrum. Astronomers place the submillimetre waveband between the far-infrared and microwave wavebands, typically taken to be between a few hundred micrometres and a millimetre. It is still common in submillimetre astronomy to quote wavelengths in 'microns', the old name for micrometre. Using submillimetre observations, astronomers examine molecular clouds and dark cloud cores with a goal of clarifying the process of star formation from earliest collapse to stellar birth. Submillimetre observations of these dark clouds can be used to determine chemical abundances and cooling mechanisms for the molecules which comprise them. In addition, submillimetre observations give information on the mechanisms for the formation and evolution of galaxies. From the g ...

Planet Formation
The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests the Solar System is formed from gas and dust orbiting the Sun. The theory was developed by Immanuel Kant and published in his ''Universal Natural History and Theory of the Heavens'' (1755) and then modified in 1796 by Pierre Laplace. Originally applied to the Solar System, the process of planetary system formation is now thought to be at work throughout the universe. The widely accepted modern variant of the nebular theory is the solar nebular disk model (SNDM) or solar nebular model. It offered explanations for a variety of properties of the Solar System, including the nearly circular and coplanar orbits of the planets, and their motion in the same direction as the Sun's rotation. Some elements of the original nebular theory are echoed in modern theories of planetary formation, but most elemen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Northwest Territories
The Northwest Territories (abbreviated ''NT'' or ''NWT''; french: Territoires du Nord-Ouest, formerly ''North-Western Territory'' and ''North-West Territories'' and namely shortened as ''Northwest Territory'') is a federal territory of Canada. At a land area of approximately and a 2016 census population of 41,790, it is the second-largest and the most populous of the three territories in Northern Canada. Its estimated population as of 2022 is 45,605. Yellowknife is the capital, most populous community, and only city in the territory; its population was 19,569 as of the 2016 census. It became the territorial capital in 1967, following recommendations by the Carrothers Commission. The Northwest Territories, a portion of the old North-Western Territory, entered the Canadian Confederation on July 15, 1870. Since then, the territory has been divided four times to create new provinces and territories or enlarge existing ones. Its current borders date from April 1, 1999, when the ...

Victoria Island (Canada)
Victoria Island ( ikt, Kitlineq, italic=yes) is a large island in the Arctic Archipelago that straddles the boundary between Nunavut and the Northwest Territories of Canada. It is the eighth-largest island in the world, and at in area, it is Canada's second-largest island. It is nearly double the size of Newfoundland (), and is slightly larger than the island of Great Britain () but smaller than Honshu (). The western third of the island lies in the Inuvik Region of the Northwest Territories; the remainder is part of Nunavut's Kitikmeot Region. The island is named after Queen Victoria, the Canadian sovereign from 1867 to 1901 (though she first became Queen in 1837). The features bearing the name "Prince Albert" are named after her consort, Albert. History In 1826 John Richardson saw the southwest coast and called it " Wollaston Land". In 1839 Peter Warren Dease and Thomas Simpson followed its southeast coast and called it "Victoria Land". A map published by John Barro ...

Centuries before Kiruna was founded in 1900, the presence of iron ore at Kiirunavaara and Luossavaara had been known by the local Sami people, Sami population. In 1696, Samuel Mört, a bookkeeper of the Kengis works, wrote on rumours about the presence of iron in the two hills.Kummu 1997, p. 96. The ore became b ...

Esrange
Esrange Space Center (short form Esrange) is a rocket range and research centre located about 40 kilometers east of the town of Kiruna in northern Sweden. It is a base for scientific research with high-altitude balloons, investigation of the aurora borealis, sounding rocket launches, and satellite tracking, among other things. Located 200 km north of the Arctic Circle and surrounded by a vast wilderness, its geographic location is ideal for many of these purposes. Esrange was built in 1964 by ESRO, the ''European Space Research Organisation'', which later became European Space Agency by merging with ELDO, the European Launcher Development Organisation. The first rocket launch from Esrange occurred on 19 November 1966. In 1972, ownership was transferred to the newly started Swedish Space Corporation. History In the 1960s Esrange was established as an ESRO sounding rocket launching range located in Kiruna (Sweden). This location was chosen because it was generally agreed tha ...

Fort Sumner, New Mexico
Fort Sumner is a village in and the county seat of De Baca County, New Mexico, United States. The population was 1,031 at the 2010 U.S. Census, down from the figure of 1,249 recorded in 2000. Fort Sumner is the spring and fall home of the Columbia Scientific Balloon Facility, and is home to the burial site of famed outlaw of the American West, Billy the Kid, who was shot and killed there in 1881. History Named after former New Mexico Territory military governor Edwin Vose Sumner, U.S. Fort Sumner was a military fort charged with the internment of nearby Navajo and Mescalero Apache populations from 1863 to 1868. The federal government closed the fort in 1868 and sold its buildings to Lucien Maxwell, a prominent New Mexico landowner, in 1870. In the latter 1870s Maxwell's son Pete befriended legendary outlaw Billy the Kid, and it was in his house that Billy was killed by Pat Garrett.
