Reynold K. Young
Reynold Kenneth Young (October 4, 1886 – February 27, 1973) was a Canadian astronomer. He served as first director of the David Dunlap Observatory from 1935 until 1946. Biography Young was born on October 4, 1886, in the town of Binbrook, Ontario, the son of Robert Young and Jean Bell. He studied at the Hamilton Collegiate Institute (the city of Hamilton's first high school), then in 1905 he matriculated to the University of Toronto. In 1909 he graduated with a B. A. degree in astronomy, and was awarded a gold medal by the Royal Astronomical Society of Canada for first class honors. With a fellowship for graduate study at the University of California, Berkeley, Young spent three years as a Fellow at the Lick Observatory. There he met his future wife, Wilhelmina Ellen Aitken, a fellow astronomer and the daughter of the observatory director, Robert G. Aitken. Young collaborated with Wilhelmina on a study of the orbital elements of the comet C/1911 O1 in 1911. In 1912, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binbrook, Ontario
Binbrook is a community in southeastern Hamilton, Ontario, in Canada. It was amalgamated into the city of Hamilton in 2001. Since 2001, hundreds of new homes have been built in Binbrook, separated from Hamilton by conservation and agricultural lands. History Armstrong's General Store was a longtime centre of community activity as was the feed mill. In the 1960s, Cybulski's Grocery Store became a hub for the small community. Knox Presbyterian Church, as well as a Baptist church, and Anglican Church all are near the centre of the village. The community of Binbrook has a rich history of agriculture and First Nations peoples. There has been evidence found of Algonquin tribes inhabiting this area. The first registry of Binbrook is in 1791 when it was called Township #11 in the District of Nassau. The plan can be found in the Department of Lands and Forests, Toronto, dated October 25, 1791, where it lists four concessions and blocks divided amongst several families. Binbrook farmers' ...

Spectroscopic Binaries
A binary star is a system of two stars that are gravitationally bound to and in orbit around each other. Binary stars in the night sky that are seen as a single object to the naked eye are often resolved using a telescope as separate stars, in which case they are called ''visual binaries''. Many visual binaries have long orbital periods of several centuries or millennia and therefore have orbits which are uncertain or poorly known. They may also be detected by indirect techniques, such as spectroscopy (''spectroscopic binaries'') or astrometry (''astrometric binaries''). If a binary star happens to orbit in a plane along our line of sight, its components will eclipse and transit each other; these pairs are called ''eclipsing binaries'', or, together with other binaries that change brightness as they orbit, ''photometric binaries''. If components in binary star systems are close enough they can gravitationally distort their mutual outer stellar atmospheres. In some cases, these ...

Solar Eclipse Of September 21, 1922
A total solar eclipse occurred on September 21, 1922. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. The greatest eclipse occurred exactly at perigee. Totality started in Ethiopia, Italian Somaliland (today's Somalia), and passed British Maldives and Christmas Island in the Straits Settlements (now in Australia) in the Indian Ocean, and Australia. Two large scientific expeditions investigated Einstein's theory of relativity The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity, proposed and published in ...

Clarence Augustus Chant
Clarence Augustus Chant (May 31, 1865 – November 18, 1956) was a Canadian astronomer and physicist. Early life and education Chant was born in Hagerman's Corners, Ontario to Christopher Chant and Elizabeth Croft. In 1882 he attended Markham High School, where he demonstrated a mathematical ability. After graduation, he attended St. Catherines Collegiate Institute and York County Model School in Toronto. He left to work as an instructor in 1884, and taught at Maxwell, Osprey Township for the following three years. By 1887 he began studying mathematics and physics at the University College of the University of Toronto, graduating in 1890. Career Upon graduation, Chant became a civil servant in Ottawa, working as a temporary clerk in the office of the Auditor General. The job offered limited prospects; however, in 1891 he was offered a fellowship at University of Toronto, where he gained an appointment as a lecturer of physics the following year.

William Edmund Harper
William Edmund Harper, March 20, 1878 – June 14, 1940, (age 62) was a Canadian astronomer. William Harper was born in Dobbington, Ontario. He attended high school in Owen Sound, then taught for three years following his graduation. When he had sufficient funds, in 1902 he entered the University of Toronto. He graduated in 1906 and became a member of the staff at the Dominion Observatory in Ottawa, Ontario, Canada. He worked with the astrophysics staff, measuring the radial velocity of stars and determining the orbits of spectroscopic binaries. (The latter are binary star systems that could not be resolved with a telescope, but their orbital motions could be studied due to the doppler effect on their spectrum.) He was awarded his master's degree in 1907 from the University of Toronto. In 1909 he was married to Maude Eugenia Hall. They had two daughters. The need for more powerful equipment was becoming apparent, and Dr. Harper suggested Victoria as a suitable location. In 1913, ...

Stellar Parallax
Stellar parallax is the apparent shift of position of any nearby star (or other object) against the background of distant objects, and a basis for determining (through trigonometry) the distance of the object. Created by the different orbital positions of Earth, the extremely small observed shift is largest at time intervals of about six months, when Earth arrives at opposite sides of the Sun in its orbit, giving a baseline distance of about two astronomical units between observations. The parallax itself is considered to be half of this maximum, about equivalent to the observational shift that would occur due to the different positions of Earth and the Sun, a baseline of one astronomical unit (AU). Stellar parallax is so difficult to detect that its existence was the subject of much debate in astronomy for hundreds of years. Thomas Henderson, Friedrich Georg Wilhelm von Struve, and Friedrich Bessel made first successful parallax measurements in 1832-1838, for the stars alpha ...

Telescope
A telescope is a device used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation. Originally meaning only an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects, the word ''telescope'' now refers to a wide range of instruments capable of detecting different regions of the electromagnetic spectrum, and in some cases other types of detectors. The first known practical telescopes were refracting telescopes with glass lenses and were invented in the Netherlands at the beginning of the 17th century. They were used for both terrestrial applications and astronomy. The reflecting telescope, which uses mirrors to collect and focus light, was invented within a few decades of the first refracting telescope. In the 20th century, many new types of telescopes were invented, including radio telescopes in the 1930s and infrared telescopes in the 1960s. Etymology The word ''telescope'' was coin ...

Aperture
In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture and focal length of an optical system determine the cone angle of a bundle of rays that come to a focus in the image plane. An optical system typically has many openings or structures that limit the ray bundles (ray bundles are also known as ''pencils'' of light). These structures may be the edge of a lens or mirror, or a ring or other fixture that holds an optical element in place, or may be a special element such as a diaphragm placed in the optical path to limit the light admitted by the system. In general, these structures are called stops, and the aperture stop is the stop that primarily determines the ray cone angle and brightness at the image point. In some contexts, especially in photography and astronomy, ''aperture'' refers to the diameter of the aperture stop rather than the physical stop or the opening itself. For example, in a telescope, the aperture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dominion Astrophysical Observatory
The Dominion Astrophysical Observatory, located on Observatory Hill, in Saanich, British Columbia, was completed in 1918 by the Canadian government. The Dominion architect responsible for the building was Edgar Lewis Horwood. The main instrument is the Plaskett telescope, proposed and designed by John S. Plaskett in 1910 with the support of the International Union for Cooperation in Solar Research. The observatory has been designated a national historic site of Canada, as it is a world-renowned facility where many discoveries about the nature of the Milky Way were made, and it was one of the world’s main astrophysical research centres until the 1960s. Public programs The Royal Astronomical Society of Canada, Victoria Centre, which has a long association with the Dominion Astrophysical Observatory and public outreach dating back to 1914, holds free public "star parties" at the DAO on select summer Saturday evenings. These events include solar and nighttime viewing with RA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Stanley Plaskett
John Stanley Plaskett (November 17, 1865 – October 17, 1941) was a Canadian astronomer. Career He worked as a machinist, and was offered a job as a mechanician at the Department of Physics at the University of Toronto, constructing apparatus and assisting with demonstrations during lectures. He found this so interesting that at the age of 30 he enrolled as an undergraduate in mathematics and physics. He stayed at the university until 1903, doing research on color photography. His formal astronomical career did not start until 1903, when he was appointed to the staff at Dominion Observatory in Ottawa, Ontario. He measured radial velocities and studied spectroscopic binaries, and performed the first detailed analysis of galactic structure. His mechanical background was very useful for constructing various instruments. He became first director of the Dominion Astrophysical Observatory in Victoria, British Columbia in 1917 (not to be confused with the old Dominion Observato ...

Meteor
A meteoroid () is a small rocky or metallic body in outer space. Meteoroids are defined as objects significantly smaller than asteroids, ranging in size from grains to objects up to a meter wide. Objects smaller than this are classified as micrometeoroids or space dust. Most are fragments from comets or asteroids, whereas others are collision impact debris ejected from bodies such as the Moon or Mars. When a meteoroid, comet, or asteroid enters Earth's atmosphere at a speed typically in excess of , aerodynamic heating of that object produces a streak of light, both from the glowing object and the trail of glowing particles that it leaves in its wake. This phenomenon is called a meteor or "shooting star". Meteors typically become visible when they are about 100 km above sea level. A series of many meteors appearing seconds or minutes apart and appearing to originate from the same fixed point in the sky is called a meteor shower. A meteorite is the remains of a meteoroid th ...
