Jean Mueller
Jean Mueller (born 1950) is an American astronomer and discoverer of comets, minor planets, and a large number of supernovas at the U.S. Palomar Observatory in California. Scientific career In 1983, she became the first woman to operate the historic Hooker telescope at Mt. Wilson Observatory and was the first woman hired as a telescope operator at Palomar Observatory in 1985. The Second Palomar Observatory Sky Survey (POSS II) got underway in August 1985, with the first of the 14" photographic glass plates being pulled off the Palomar's Samuel Oschin telescope (then called the 48-inch Schmidt Camera). Jean Mueller was hired as the ''48-Inch Night Assistant'' in July of that year, and worked in the capacity as observer and telescope operator for the duration. She took over 5500 photographic plates and had the honor of setting the telescope and removing the final plate from the historic Schmidt Camera on June 3, 2000, as well as discovering her last supernova, 2000cm, on that sa ...

Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, natural satellite, moons, comets and galaxy, galaxies – in either observational astronomy, observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, Sun, solar astronomy, the Star formation, origin or stellar evolution, evolution of stars, or the galaxy formation and evolution, formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational astronomy, observational and theoretical astronomy, theoretical. Observational astronomers make direct observations of Astronomical object, celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate C ...

9162 Kwiila
__NOTOC__ Year 916 ( CMXVI) was a leap year starting on Monday (link will display the full calendar) of the Julian calendar. Events By place Europe * Sicilian Berbers in Agrigento revolt and depose the independent Emir Ahmed ibn Khorob. They offer Sicily to the Fatimid Caliphate in Ifriqiya (modern Tunisia). Caliph Abdullah al-Mahdi Billah welcomes this turn of events, but refuses to grant the Berber rulers their autonomy. He sends a Fatimid expeditionary force under Abu Said Musa which lands in Sicily and, with some difficulty, takes control of the island. Abdullah al-Mahdi Billah appoints Salam ibn Rashid as the emir of Sicily. Ahmed ibn Khorob is dispatched to Raqqada and executed. Britain * Lady Æthelflæd, daughter of the late King Alfred the Great and the widow of Earl Æthelred of Mercia, sends an army into Brycheiniog to avenge the murder of the Mercian abbot Ecbryht and his companions. They seize and burn the royal fort of King Tewdr of Brycheiniog at Ll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apollo Asteroid
The Apollo asteroids are a group of near-Earth asteroids named after 1862 Apollo, discovered by German astronomer Karl Reinmuth in the 1930s. They are Earth-crossing asteroids that have an orbital semi-major axis greater than that of the Earth (a > 1 AU) but perihelion distances less than the Earth's aphelion distance (q < 1.017 AU). , the number of known Apollo asteroids is 10,485, making the class the largest group of s (''cf''. the , Amor and Atira asteroids), [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Near-Earth Objects
A near-Earth object (NEO) is any small Solar System body whose orbit brings it into proximity with Earth. By convention, a Solar System body is a NEO if its closest approach to the Sun (perihelion) is less than 1.3 astronomical units (AU). If a NEO's orbit crosses the Earth's orbit, and the object is larger than across, it is considered a potentially hazardous object (PHO). Most known PHOs and NEOs are asteroids, but a small fraction are comets. There are over 30,503 known near-Earth asteroids (NEAs) and over a hundred known short-period near-Earth comets (NECs). A number of solar-orbiting meteoroids were large enough to be tracked in space before striking the Earth. It is now widely accepted that collisions in the past have had a significant role in shaping the geological and biological history of the Earth. Asteroids as small as in diameter can cause significant damage to the local environment and human populations. Larger asteroids penetrate the atmosphere to the sur ...

Minor Planet Center
The Minor Planet Center (MPC) is the official body for observing and reporting on minor planets under the auspices of the International Astronomical Union (IAU). Founded in 1947, it operates at the Smithsonian Astrophysical Observatory. Function The Minor Planet Center is the official worldwide organization in charge of collecting observational data for minor planets (such as asteroids), calculating their orbits and publishing this information via the '' Minor Planet Circulars''. Under the auspices of the International Astronomical Union (IAU), it operates at the Smithsonian Astrophysical Observatory, which is part of the Center for Astrophysics along with the Harvard College Observatory. The MPC runs a number of free online services for observers to assist them in observing minor planets and comets. The complete catalogue of minor planet orbits (sometimes referred to as the "Minor Planet Catalogue") may also be freely downloaded. In addition to astrometric data, the MPC collect ...
