By the 1950s, the development of civil jets grew, beginning with the de Havilland Comet, though the first widely-used passenger jet was the Boeing 707, because it was much more economical than other planes at the time.

Comet Shoemaker – Levy 9 ( formally designated D / 1993 F2 ) was a comet that broke apart and collided with Jupiter in July 1994, providing the first direct observation of an extraterrestrial collision of Solar System objects.

Comet Shoemaker – Levy 9 was the ninth periodic comet ( a comet whose orbital period is 200 years or less ) discovered by the Shoemakers and Levy, hence its name.

Its mission was extended twice to include an encounter with Comet Borrelly and further engineering testing.

However, the flyby of Comet Borrelly was a great success and returned extremely detailed images of the comet's surface.

The first science fiction fanzine, The Comet, was published in 1930 by the Science Correspondence Club in Chicago and edited by Raymond A. Palmer and Walter Dennis.

NASA's Deep Space One was a very successful test of a prototype ion drive, which fired for a total of 678 days and enabled the probe to run down Comet Borrelly, a feat which would have been impossible for a chemical rocket.

At age six, he observed the Great Comet of 1577, writing that he " was taken by mother to a high place to look at it.

Comet Bode ( C / 1779 A1 ) is named after him ; its orbit was calculated by Erik Prosperin.

It was in 1866 – 67 that information on Comet Tempel-Tuttle was gathered pointing it out as the source of the meteor shower.

The meteoroids from the 1733 passage of Comet Tempel-Tuttle resulted in the 1866 storm and the 1966 storm was from the 1899 passage of the comet.

Later it was speculated that the probe passed through the debris of Comet D / Swift, and even made a close flyby of that comet's possibly shattered nucleus at only 20 million kilometers.

According to one story that first appeared in a 1475 posthumous biography and was subsequently embellished and popularized by Pierre-Simon Laplace, Callixtus III excommunicated the 1456 apparition of Halley's Comet, believing it to be an ill omen for the Christian defenders of Belgrade from the besieging armies of the Ottoman Empire.

The first science fiction fanzine, The Comet, was published in 1930.

In May 1930 the first science fiction fan magazine, The Comet, was produced by the Chicago branch of the Science Correspondence Club under the editorship of Raymond A. Palmer ( later a noted, and notorious, sf magazine editor ) and Walter Dennis.

The cult of this noblest of Whigs, “ the Genius of England and the Comet of his Age ,” was well advanced toward idolatry at least five years before the Stamp Act.

* September 18 – Great Comet of 1882: Her Majesty's Astronomer at the Cape, David Gill, reported watching the comet rise a few minutes before the Sun and described it as " The nucleus was then undoubtedly single, and certainly rather under than over 4 ″ in diameter ; in fact, as I have described it, it resembled very much a star of the 1st magnitude seen by daylight.

* August 1 – The Comet of 1729, possibly the largest comet on record, was discovered by Nicolas Sarabat.

Amongst his other observations during this time was that of the return of Comet Halley.

Comet Lulin was passing through the constellation Libra when Swift imaged it on January 28, 2009.

NASA's Swift Gamma-ray Explorer satellite was monitoring Comet Lulin as it closed to 63 Gm of Earth.

Although he had suspected that two comets that had appeared in succession in 1680 and 1681 were the same comet before and after passing behind the Sun ( he was later found to be correct ; see Newton's Comet ), he was unable to completely reconcile comets into his model.

The first roller coaster was built in 1904 and was called the Chase Through the Clouds which was replaced by the Velvet roller coaster ( renamed the Comet ).

The Comet and Viscount aircraft were replaced with five Trident jets three of them acquired from BEA.

The field is a base for NASA's administrative, cargo transport and high-altitude aircraft, which also includes NASA's fleet of T-38 Talon jets bailed to the agency from USAF, Gulfstream Shuttle Training Aircraft, and a former USN C-9 " Weightless Wonder VI " replaced the USAF NKC-135 aircraft known as the Vomit Comet, a zero-g trainer.

The Comet was introduced to the Canadian market for the 1961 model year and replaced the Frontenac as the compact offering by Mercury-Meteor dealers.

Nine years later, it was replaced by a more substantial 60-foot ( 20 m ) tall wooden observatory tower, from which Donati's Comet was photographed in 1858.

* Ireland retired in 1969, replaced with the Comet tank

Comet 105P / Singer Brewster, discovered by Stephen Singer-Brewster, should by rights have been named " 105P / Singer-Brewster ", but this would have led most readers to believe it had been a joint discovery by two astronomers named Singer and Brewster, respectively, so the hyphen was replaced by a space.

In 1949 the Dakotas were replaced by Vickers Valletas and Handley Page Hastings transport aircraft ; in 1955 the squadron moved to RAF Lyneham from RAF Fayid in Egypt to operate the DH Comet until 1975.

The Fairmont was the successor to the Maverick ; its Mercury counterpart was the Mercury Zephyr, which replaced the Comet.

These two tanks-and their successors, the Comet and the Centurion, which were already on the drawing board-were to have replaced the Sherman in British service, and so the prospect of spending time and money mounting a 17 pounder on the Sherman was not seen as desirable.

Awarded the Albert Medal ( later replaced by the George Cross ) on 21 February 1919, for gallantry in saving lives at sea on 4 August 1918 while serving on HMS Comet during World War I.

It was at this time that the moniker " Star Junior " was dropped and replaced with the name " Comet.

This meteorite is believed to have been dislodged from a near-Earth orbit by the passing Halley's Comet.

He is credited by many with first popularizing this form of music in the early 1950s with his group Bill Haley & His Comets ( inspired by Halley's Comet ) and million selling hits such as, " Rock Around the Clock ", " See You Later Alligator ", and " Shake Rattle and Roll ".

During the Labor Day weekend in 1952, The Saddlemen were renamed Bill Haley with Haley's Comets ( inspired by a popular mispronunciation of Halley's Comet ), and in 1953, Haley's recording of " Crazy Man, Crazy " ( co-written by Haley and his bass player, Marshall Lytle although Lytle would not receive credit until 2001 ) became the first rock and roll song to hit the American charts, peaking at no. 15 on Billboard and no. 11 on Cash Box.

In science fiction, the impact of comets has been depicted as a threat overcome by technology and heroism ( Deep Impact, 1998 ), or as a trigger of global apocalypse ( Lucifer's Hammer, 1979 ) or of waves of zombies ( Night of the Comet, 1984 ).

Such images were of higher resolution than the only previous pictures, of Halley's Comet taken by the Giotto spacecraft.

Bessel came to the attention of a major figure of German astronomy at the time, Heinrich Wilhelm Olbers, by producing a refinement on the orbital calculations for Halley's Comet.

The others usually begin with the world rushing to catastrophe, until people realise a better way of living: whether by mysterious gases from a comet causing people to behave rationally and abandoning a European war ( In the Days of the Comet ( 1906 )), or a world council of scientists taking over, as in The Shape of Things to Come ( 1933, which he later adapted for the 1936 Alexander Korda film, Things to Come ).
