Space
Space is a three-dimensional continuum containing positions and directions. In classical physics, physical space is often conceived in three linear dimensions. Modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as '' spacetime''. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. In the 19th and 20th centuries mathematicians began to examine geometries that are non-Euclidean, in which space is conceived as '' curved'', rather than '' flat'', as in the Euclidean space. According to Albert Einstein's theory of general relativity, space around gravitational fields deviates from Euclidean space. Experimental tests of general relativity have confirmed that non-Euclidean geometries provide a bet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Comet Hale-Bopp
A comet is an icy, small Solar System body that warms and begins to release gases when passing close to the Sun, a process called outgassing. This produces an extended, gravitationally unbound atmosphere or coma surrounding the nucleus, and sometimes a tail of gas and dust gas blown out from the coma. These phenomena are due to the effects of solar radiation and the outstreaming solar wind plasma acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth's diameter, while the tail may stretch beyond one astronomical unit. If sufficiently close and bright, a comet may be seen from Earth without the aid of a telescope and can subtend an arc of up to 30° (60 Moons) across the sky. Comets have been observed and recorded since ancient times by many cultures and religions. Comets usually have highly eccentric elli ...

Astronomical League
The Astronomical League is an umbrella organization of amateur astronomy societies. Currently their membership consists of over 330 organizations across the United States, along with a number of Members-at-Large, Patrons, and Supporting members. The mission of the Astronomical League is to promote the science of astronomy by (1) fostering astronomical education; (2) providing incentives for astronomical observation and research; and (3) assisting communication among amateur astronomical societies. The Astronomical League provides a number of observing awards to members locating and describing certain specified astronomical objects or events, and produces a periodical publication, ''The Reflector''. History The beginning of the Astronomical League dates back to 1939 when members of eleven amateur astronomical societies met at the American Museum of Natural History in New York City. Similar meetings followed in Pittsburgh, 1940, Washington D.C., 1941, and Detroit, 1946. During th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Edgar Wilson Award
The Edgar Wilson Award is an annual international award established in 1998 consisting of a monetary award and a plaque allocated annually to amateur comet discoverers. It is administered by the Smithsonian Astrophysical Observatory (SAO) through the IAU's Central Bureau for Astronomical Telegrams (CBAT). Origins Edgar Wilson was an American businessman who lived in Lexington, Kentucky. After he died in 1976, the Edgar Wilson Charitable Trust Fund was set up and awards were allocated in accordance with the terms of his bequest. Eligibility Each year the award is divided between amateur astronomers who during that year, using amateur equipment, discover one or more new comets which are then officially named after them. The annual total award is of the order of US$20,000 but fluctuates from year to year. Since 2014 the award was not given, but reestablished in 2024 (without a donated price). In any year when there are no eligible discoverers, CBAT makes the award to the amateur astro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
