Paul Boltwood
Paul Boltwood (1943 – September 25, 2017) was a Canadian amateur astronomer. He was engaged in developing hardware and software for deep sky imaging and in research of brightness variations in active galactic nuclei. He was also acknowledged for his studies of near-nucleus activity in Comet Hyakutake. Boltwood died in Stittsville, Ontario. Early life and education Paul Boltwood was born in Vancouver, British Columbia in 1943. He first became interested in astronomy around age 12 and had built his own telescope by age 15. He received a bachelor's degree in mathematics from the University of British Columbia in 1966. He pursued a career in computer software and systems design, with an emphasis on signal and image processing. Work in astronomy Paul Boltwood founded Boltwood Systems Corporation in 1980, which manufactured cloud sensors for amateur astronomers. In the early 1990s, he constructed an observatory in his backyard near Ottawa, Ontario, with a CCD camera of his ow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amateur Astronomy
Amateur astronomy is a hobby where participants enjoy observing or imaging celestial objects in the sky using the unaided eye, binoculars, or telescopes. Even though scientific research may not be their primary goal, some amateur astronomers make contributions in doing citizen science, such as by monitoring variable stars, double stars, sunspots, or occultations of stars by the Moon or asteroids, or by discovering transient astronomical events, such as comets, galactic novae or supernovae in other galaxies. Amateur astronomers do not use the field of astronomy as their primary source of income or support, and usually have no professional degree in astrophysics or advanced academic training in the subject. Most amateurs are hobbyists, while others have a high degree of experience in astronomy and may often assist and work alongside professional astronomers. Many astronomers have studied the sky throughout history in an amateur framework; however, since the beginning of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bradley Schaefer
Bradley Elliott Schaefer is a professor of astronomy and astrophysics at Louisiana State University. He received his PhD from the Massachusetts Institute of Technology in 1983. Early life In addition to his academic pursuits, Schaefer is remembered at MIT as the founder of the annual MIT Mystery Hunt in 1981 during his graduate studies there. The tradition of the hunt continues today. Scientific career His research interests include the use of photometry of exploding objects to get results of interest for physical cosmology. He has also researched the dwarf planet Pluto with the aim of understanding the atmospheric variability of the system. Bradley has also studied KIC 8462852, a star with unusual within-day light fluctuations of about 20 percent, and found that the century-long light (1890 to 1989) from the star faded by about 20 percent as well, adding to its unusual luminosity.

21st-century Canadian Astronomers
The 1st century was the century spanning AD 1 ( I) through AD 100 ( C) according to the Julian calendar. It is often written as the or to distinguish it from the 1st century BC (or BCE) which preceded it. The 1st century is considered part of the Classical era, epoch, or historical period. The 1st century also saw the appearance of Christianity. During this period, Europe, North Africa and the Near East fell under increasing domination by the Roman Empire, which continued expanding, most notably conquering Britain under the emperor Claudius (AD 43). The reforms introduced by Augustus during his long reign stabilized the empire after the turmoil of the previous century's civil wars. Later in the century the Julio-Claudian dynasty, which had been founded by Augustus, came to an end with the suicide of Nero in AD 68. There followed the famous Year of Four Emperors, a brief period of civil war and instability, which was finally brought to an end by Vespasian, ninth Roman emperor ...

Syuichi Nakano
is a Japanese astronomer. He specializes in the study of comets, in particular calculating their orbits and making predictions about when periodic comets will return for another perihelion approach. It is considerably more difficult to predict the orbits of comets than of other types of Solar System objects, since their orbits are susceptible not only to perturbations from the planets but also to non-gravitational forces due to the release of gaseous material in the form of a comet's coma and tail. He is affiliated with the Computing & Minor Planet Sections (Center for Astrodynamics) of the Oriental Astronomical Association in Sumoto, Japan. He publishes the ''Nakano Notes'' on comet observations and ephemerides. In 2001 he won the Amateur Achievement Award of the Astronomical Society of the Pacific. The asteroid 3431 Nakano is named after him, and asteroid 3983 Sakiko is named after his sister. 1026 Ingrid was reidentified in 1986 by Syuichi Nakano, ending its time as a l ...

Warren Offutt
Warren B. Offutt (February 13, 1928 – September 20, 2017) was an American amateur astronomer and amateur radio operator. Offutt is credited by the Minor Planet Center with the discovery of 17 asteroids and has notably collaborated with professional astronomers in observing Kuiper belt objects (KBOs). In 1999 he won the Amateur Achievement Award of the Astronomical Society of the Pacific. Offutt and his wife, Beverly (since deceased), moved from Illinois to New Mexico when he retired from engineering, specializing in precision astrometry of faint objects in the Solar System. He operates the ''W & B Observatory'' () in the U.S. village of Cloudcroft, New Mexico, in the Sacramento Mountains, at an altitude of 2500 m (8300 ft). In 1997, Offutt helped with three more major discoveries, among them confirmation of a then-newly discovered moon of Uranus, Sycorax Sycorax is an unseen character in William Shakespeare's play ''The Tempest'' (1611). She is a vicious a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asteroid
An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere. Of the roughly one million known asteroids the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 AU from the Sun, in the main asteroid belt. Asteroids are generally classified to be of three types: C-type, M-type, and S-type. These were named after and are generally identified with carbonaceous, metallic, and silicaceous compositions, respectively. The size of asteroids varies greatly; the largest, Ceres, is almost across and qualifies as a dwarf planet. The total mass of all the asteroids combined is only 3% that of Earth's Moon. The majority of main belt asteroids follow slightly elliptical, stable orbits, revolving in the same direction as the Earth and taking from three to six years to comple ...

Amateur Achievement Award Of Astronomical Society Of The Pacific
The Gordon Myers Amateur Achievement Award, known until 2018 as the Amateur Achievement Award of the Astronomical Society of the Pacific, is one of nine annual astronomical awards managed by the Astronomical Society of the Pacific. It recognizes "significant contributions to astronomy or amateur astronomy by those not employed in the field of astronomy in a professional capacity." The contributions can be done in the fields of both observational astronomy or astronomical technologies. The award has been given to amateur astronomers from various countries since 1979 and has become one of the most geographically diverse astronomical awards. Award winners receive a commemorative plaque, which is presented at the Annual Meeting Awards Banquet. The monetary value of the award is US$500. Candidates can be nominated by any member of the astronomical community (with the exception of the nominees themselves and their families) and the nominations should be accompanied by other letters of ...
