Star
A star is a luminous spheroid of plasma (physics), plasma held together by Self-gravitation, self-gravity. The List of nearest stars and brown dwarfs, nearest star to Earth is the Sun. Many other stars are visible to the naked eye at night sky, night; their immense distances from Earth make them appear as fixed stars, fixed points of light. The most prominent stars have been categorised into constellations and asterism (astronomy), asterisms, and many of the brightest stars have proper names. Astronomers have assembled star catalogues that identify the known stars and provide standardized stellar designations. The observable universe contains an estimated to stars. Only about 4,000 of these stars are visible to the naked eye—all within the Milky Way galaxy. A star's life star formation, begins with the gravitational collapse of a gaseous nebula of material largely comprising hydrogen, helium, and traces of heavier elements. Its stellar mass, total mass mainly determines it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mario Livio 22 Sep 2013 National Book Festival
Mario (; ) is a character created by the Japanese game designer Shigeru Miyamoto. He is the star of the ''Mario'' franchise, a recurring character in the ''Donkey Kong'' franchise, and the mascot of the Japanese video game company Nintendo. Mario is an Italian plumber who lives in the Mushroom Kingdom with his younger twin brother, Luigi. Their adventures generally involve rescuing Princess Peach from the villain Bowser while using power-ups that give them different abilities. Mario is distinguished by his large nose and mustache, overalls, red cap, and high-pitched, exaggerated Italian accent. Mario debuted as the player character of ''Donkey Kong'', a 1981 platform game. Miyamoto created Mario because Nintendo was unable to license Popeye as the protagonist. The graphical limitations of arcade hardware influenced Mario's design, such as his nose, mustache, and overalls, and he was named after Nintendo of America's landlord, Mario Segale. Mario then starred in '' Mario Br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carnegie Centenary Professor
The Carnegie Trust for the Universities of Scotland is a charitable trust established by Andrew Carnegie in 1901 for the benefit of the universities of Scotland, their students and their staff. The incorporation of the Trust was by royal charter in August 1902, later replaced in July 1978. The endowment of the Trust on establishment was $10 million (an unprecedented gift, amounting to around 200-times the annual governmental funding of the four Scottish universities at the time). In 2004-5, the assets of the Trust amounted to £58million, which enabled awards of £1,667,540 to be made. Under the terms set down by Andrew Carnegie, one half of the Trust's income is reserved for "the improvement and expansion of the Universities of Scotland" with the other half to go towards "the payment of fees of students of Scottish birth or extraction in respect of courses leading to a degree of a Scottish University". The ex–officio Trustees of the Trust are: the Principals of the Unive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

American Men And Women Of Science
''American Men and Women of Science'' is a biographical reference work on leading scientists in the United States and Canada, published as a series of books and online by Gale. The first edition was published in 1906, named ''American Men of Science''; the work broadened its title to include women in 1971. (However, women were listed in it before that. Two women, Grace Andrews and Charlotte Angas Scott, were listed in the first edition of ''American Men of Science'' in 1906.) ''American Men and Women of Science'' profiles living persons in the physical and biological fields, as well as public health scientists, engineers, mathematicians, statisticians, and computer scientists. According to the publisher, those included met the following criteria: (1) Distinguished achievement, by reason of experience, training or accomplishment, including contributions to literature, coupled with continuing activity in scientific work; or (2) Research activity of high quality in science as evid ...

Planetary Nebula
A planetary nebula is a type of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from red giant stars late in their lives. The term "planetary nebula" is a misnomer because they are unrelated to planets. The term originates from the planet-like round shape of these nebulae observed by astronomers through early telescopes. The first usage may have occurred during the 1780s with the English astronomer William Herschel who described these nebulae as resembling planets; however, as early as January 1779, the French astronomer Antoine Darquier de Pellepoix described in his observations of the Ring Nebula, "very dim but perfectly outlined; it is as large as Jupiter and resembles a fading planet". Though the modern interpretation is different, the old term is still used. All planetary nebulae form at the end of the life of a star of intermediate mass, about 1-8 solar masses. It is expected that the Sun will form a planetary nebula at the end of i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binary Star
A binary star or binary star system 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 as separate stars using a telescope, 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 each other's outer stellar atmospheres. ...
