Miss Mitchell's Comet
Miss Mitchell's Comet, formally designated as C/1847 T1, is a non-periodic comet that American astronomer Maria Mitchell discovered in 1847. The discovery was initially credited to Francesco de Vico. Vico, observing from Rome, was the first to report the comet's discovery in Europe. However, Mitchell observed the comet two days before Vico did, so she became recognized as the comet's discoverer. The comet had a weakly hyperbolic orbit solution while inside the planetary region of the Solar System. An orbit solution when the comet is outside of the planetary region shows that the comet is bound to the Sun.

Maria Mitchell
Maria Mitchell ( ; August 1, 1818 – June 28, 1889) was an American astronomer, librarian, naturalist, and educator. In 1847, she discovered a comet named 1847 VI (modern designation C/1847 T1) that was later known as " Miss Mitchell's Comet" in her honor. She won a gold medal prize for her discovery, which was presented to her by King Christian VIII of Denmark in 1848. Mitchell was the first internationally known woman to work as both a professional astronomer and a professor of astronomy after accepting a position at Vassar College in 1865. She was also the first woman elected Fellow of the American Academy of Arts and Sciences and the American Association for the Advancement of Science. Mitchell is the namesake of the Maria Mitchell Association, the Maria Mitchell Observatory, and the Maria Mitchell Aquarium. Early years (1818–1846) Maria Mitchell was born on August 1, 1818, on the island of Nantucket, Massachusetts, to Lydia Coleman Mitchell, a library worker, and ...

Nantucket
Nantucket () is an island in the state of Massachusetts in the United States, about south of the Cape Cod peninsula. Together with the small islands of Tuckernuck Island, Tuckernuck and Muskeget Island, Muskeget, it constitutes the Town and County of Nantucket, a Consolidated city-county, combined county/town government. Nantucket is the southeasternmost town in both Massachusetts and the New England region. The name "Nantucket" is adapted from similar Eastern Algonquian languages, Algonquian names for the island. Nantucket is a tourism, tourist destination and summer colony. Due to tourists and seasonal residents, the population of the island increases to around 80,000 during the summer months. The average sale price for a single-family home was $2.3 million in the first quarter of 2018. The National Park Service cites Nantucket, designated a National Historic Landmark District in 1966, as being the "finest surviving architectural and environmental example of a late 18th- an ...

Julian Day
The Julian day is a continuous count of days from the beginning of the Julian period; it is used primarily by astronomers, and in software for easily calculating elapsed days between two events (e.g., food production date and sell by date). The Julian period is a chronological interval of 7980 years, derived from three multi-year cycles: the Indiction, Solar, and Lunar cycles. The last year that was simultaneously the beginning of all three cycles was , so that is year 1 of the current Julian period, making AD year of that Period. The next Julian Period begins in the year AD 3268. Historians used the period to identify Julian calendar years within which an event occurred when no such year was given in the historical record, or when the year given by previous historians was incorrect. The Julian day number (JDN) has the same epoch as the Julian period, but counts the number of days since the epoch rather than the number of years since then. Specifically, ...

Non-periodic Comet
The following is a list of comets with a very high Orbital eccentricity, eccentricity (generally 0.99 or higher) and a Orbital period, period of over 1,000 years that do not quite have a high enough Escape velocity, velocity to escape the Solar System. Often, these comets, due to their extreme Semimajor axis, semimajor axes and eccentricity, will have small orbital interactions with planets and minor planets, most often ending up with the comets fluctuating significantly in their Orbit, orbital path. These comets probably come from the Oort cloud, a cloud of comets orbiting the Sun from ~10,000 to roughly 50,000 Astronomical unit, AU. The actual orbit of these comets significantly differs from the provided coordinates. A Solar System Barycenter, barycentric orbit computed at an epoch (astronomy), epoch when the object is located beyond all the planets is a more accurate measurement of its long-term orbit.

Astronomer
An astronomer is a scientist in the field of astronomy who focuses on a specific question or field outside the scope of Earth. Astronomers 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 typically 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 Con ...

Francesco De Vico
Father Francesco de Vico (also known as de Vigo, De Vico and even DeVico; 19 May 1805 in Macerata – 15 November 1848 in London) was an Italian astronomer and a Jesuit priest. Biography He was educated at the college of Urbino, and became in 1835 assistant superintendent, and in 1839 director of the Vatican Observatory. The Revolutions of 1848 in the Italian states cut short his observing career, as he was forced into exile, touring Paris, London, and the United States, where he was received by the President. He was pleased with his reception in the U.S. and wished to settle there at Georgetown College, but first returned to Europe to try to recruit some colleagues to join him and purchase instruments for an observatory to be erected under his direction in New York. Unfortunately, worn out from the travel, he died in London in November of that same year Work He found a remarkable number of comets in a relatively short time, including periodic comets 54P/de Vico-Swift-NEAT and ...

American Physical Society
The American Physical Society (APS) is a not-for-profit membership organization of professionals in physics and related disciplines, comprising nearly fifty divisions, sections, and other units. Its mission is the advancement and diffusion of knowledge of physics. It publishes more than a dozen scientific journals, including the prestigious '' Physical Review'' and ''Physical Review Letters'', and organizes more than twenty science meetings each year. It is a member society of the American Institute of Physics. Since January 2021, it is led by chief executive officer Jonathan Bagger. History The American Physical Society was founded on May 20, 1899, when thirty-six physicists gathered at Columbia University for that purpose. They proclaimed the mission of the new Society to be "to advance and diffuse the knowledge of physics", and in one way or another the APS has been at that task ever since. In the early years, virtually the sole activity of the APS was to hold scientific m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Association For Women In Science
The Association for Women in Science (AWIS) was founded in 1971 at the annual Federation of American Societies for Experimental Biology (FASEB) meeting. The organization aims to combat job discrimination, lower pay, and professional isolation. The main issue areas that the modern Association addresses are fair compensation, work-life integration, attrition, and professional development. History AWIS was founded in 1971 at the annual meeting of the Federation of American Societies for Experimental Biology (FASEB), after a series of champagne brunches organized by an informal women's caucus. After establishing an executive director and an office in Washington, DC, chapters were organized across the country for individual members. Its founding co-presidents were Neena Schwartz and Judith Pool. Along with other women in science associations, an early AWIS action involved initiating a class action lawsuit against the National Institutes of Health (NIH) in response to poor representati ...

Astronomical Objects Discovered In 1847
Astronomy is a natural science that studies astronomical object, celestial objects and the phenomena that occur in the cosmos. It uses mathematics, physics, and chemistry in order to explain their origin and their overall chronology of the Universe, evolution. Objects of interest include planets, natural satellite, moons, stars, nebulae, galaxy, galaxies, meteoroids, asteroids, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond atmosphere of Earth, Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Egyptian astronomy, Egyptians, Babylonian astronomy, Babylonians, Greek astronomy, Greeks, Indian astronomy, Indians, Ch ...

Non-periodic Comets
A periodic function, also called a periodic waveform (or simply periodic wave), is a function that repeats its values at regular intervals or periods. The repeatable part of the function or waveform is called a ''cycle''. For example, the trigonometric functions, which repeat at intervals of 2\pi radians, are periodic functions. Periodic functions are used throughout science to describe oscillations, waves, and other phenomena that exhibit periodicity. Any function that is not periodic is called ''aperiodic''. Definition A function is said to be periodic if, for some nonzero constant , it is the case that :f(x+P) = f(x) for all values of in the domain. A nonzero constant for which this is the case is called a period of the function. If there exists a least positive constant with this property, it is called the fundamental period (also primitive period, basic period, or prime period.) Often, "the" period of a function is used to mean its fundamental period. A function ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
