	The Columbus Dispatch : John Switzer commentary: Search for tiny owls leads to small comet
		While we were standing in the darkness waiting for the owls to fly into the nets, we all noticed how bright the stars were out in the country, away from the bright lights of the city.
		If you want to try to locate the comet, Perseus is a fall and winter constellation that is now rising in the northeast just after dark, Burns said.
		Although Holmes is a rather minor comet, Burns said it's a good experience for stargazers, even if it doesn't look like much to someone without a telescope.

	Comet Introduction
		Comets are small, fragile, irregularly shaped bodies composed of a mixture of non-volatile grains and frozen gases.
		Comet structures are diverse and very dynamic, but they all develop a surrounding cloud of diffuse material, called a coma, that usually grows in size and brightness as the comet approaches the Sun.
		When a comet approaches within a few AU of the Sun, the surface of the nucleus begins to warm, and volatiles evaporate.

	SPACE.com -- New Comet Now Visible to Naked Eye
		Comet c/2004 Q2 (Machholz) was photographed on Sept. 14 by Gianluca Masi and Franco Mallia, as part of an educational project in Italy using the SoTIE telescope in Las Campanas, Chile.
		Comets are made of rocky material and icy mixtures of water and various other chemicals.
		Comet Machholz, officially named c/2004 Q2, is not expected to produce the sort of spectacular display put on by comet Hale-Bopp in 1997 or the periodically stunning Halley's comet.

	Comet Holmes bright enough to see in northeast sky
		Comet 17P/Holmes is doing something of a return engagement in the night sky.
		The comet that until Oct. 23 had to be found with a telescope suddenly began brightening and now can be seen with the naked eye.
		Comet Holmes does appear different than other comets in that there is not a long tail.

		The comets are ice-rich bodies that become prominent when heat from the sun causes their trapped volatiles to sublimate.
		However, most of the mass of a comet is contained within a comparatively tiny central nucleus, and it is this body that is of the highest scientific interest because of its likely identity as a planetesimal from the outer regions of the solar nebula.

	cbs11tv.com - Europe Comet Probe Makes Key Mars Flyby
		Rosetta is scheduled to orbit the comet as it hurtles around the sun and release a small lander that will make the first touchdown on a comet.
		Researchers hope the robotic explorer will be able to photograph the appearance of the comet's tail, a stream of gases and dust that arises when the icy body warms as it approaches the sun.
		Comets are among the most primitive objects in the 4.6-billion-year-old solar system, and analyses of their composition could shed light on the system's early history.

	Comet - Wikipedia, the free encyclopedia
		Most comets are believed to originate in a cloud (the Oort cloud) at large distances from the Sun consisting of debris left over from the condensation of the solar nebula; the outer edges of such nebulae are cool enough that water exists in a solid (rather than gaseous) state.
		Comets are now designated by the year of their discovery followed by a letter indicating the half-month of the discovery and a number indicating the order of discovery (a system similar to that already used for asteroids), so that the fourth comet discovered in the second half of February 2006 would be designated 2006 D4.
		He rejected the ideas of several earlier philosophers that comets were planets, or at least a phenomenon related to the planets, on the grounds that while the planets confined their motion to the circle of the Zodiac, comets could appear in any part of the sky.

	comet
		Comets are leftovers from the formation of the Solar System and are believed to exist in vast numbers in the Oort Cloud and, to a lesser extent, in the Kuiper Belt.
		As a comet draws nearer to the Sun, solar radiation causes the comet's frozen gases to sublime (turn directly from a solid into a gas) and be released, so that, in addition to the frozen nucleus, several new features develop.
		As well as the many individual comets on record, two distinct comet families are known: the Jupiter family, whose members have different origins but have all been captured by Jupiter into similar orbits, and the Kreutz family of sungrazing-comets, which may be fragments of a single parent body.

	Comet Club Introduction
		Comets are important members of our solar system, and their study is important to mankind.
		Of these, 184 are periodic comets (orbital periods less than 200 years); some of the remainder are no doubt periodic as well, but their orbits have not been determined with sufficient accuracy to tell for sure.
		(5f) While comets are quite noticeable because of the coma/tail, two or more observations should be used to verify the motion and identity of the comet that is dimmer than 6th magnitude and/or does not have a noticeable tail or coma.

	NASA - Comet
		The nucleus of a comet is a ball of ice and rocky dust particles that resembles a dirty snowball.
		As a comet nears the inner solar system, heat from the sun vaporizes some of the ice on the surface of the nucleus, spewing gas and dust particles into space.
		Comets that pass near the sun come from two groups of comets near the outer edge of the solar system, according to astronomers.

		Comets are small, fragile, irregularly shaped bodies composed of a mixture of non-volatile grains and frozen gases.
		While comets are traditionally named for their discoverers, obviously some difficulties can arise when a team of observers discovers a comet, and/or independent and near-simultaneous discoveries are made of the same object.
		Comet Shoemaker-Levy 9 was discovered photographically by the husband and wife scientific team of Carolyn S. and Eugene M. Shoemaker and David H. Levy on March 24, 1993, using the 0.46-m (18-in.) Schmidt telescope at Palomar Observatory in California.

		The comet was closest to Earth (0.26 AU) on November 9, and observations continued as the comet's elongation from the sun decreased.
		The comet's third discovery was made by Jean Louis Pons (Marseille, France) on 1805 October 20, with independent discoveries being made by Johann Sigismund Huth (Frankfurt an der Oder, Germany) on the 21st and Alexis Bouvard on the 22nd.
		The comet's longest recorded tail length was 3 degrees in 1805, while it reached 2 degrees in 1871 and 1961.

	Comet
		The Web version of Comet allows you to select motifs from a small library that we have constructed, or you can enter your own matrices, for example by copying and pasting them directly from the TRANSFAC database.
		Comet assigns a positive score to each motif using the standard method of log likelihood ratios, and subtracts a 'gap penalty' linearly proportional to the distances between motifs.
		Comet's output is a list of predicted cis-element clusters, whereas Cister's output consists of posterior probability curves indicating the likelihood that each basepair is within a cis-element cluster.

		The associated comet swarm cycle is in a 3:2 resonant orbit with Vulcan and is estimated to be 3,353 years in the STRIKE DATES section of the 1999 Paper (verses the 3600-year cycle estimated in this channeled material).
		Comets travel with a swarm of debris particles gathered from their sojourns in the outer solar system.
		Comet orbits are not perfectly stable, especially when one considers that these comets may have last rounded the Sun (a major celestial object) about 3200 years ago.

		While Comet is similar to Ajax in that it’s asynchronous, applications that implement the Comet style can communicate state changes with almost negligible latency.
		Comet improves application responsiveness for collaborative, multi-user applications and does it without the performance headaches associated with intermittent polling.
		Comet may be a new name for an old set of concepts wrapped in some pretty grotty hacks, but that in no way diminishes the market impact it will have (and is already having).

	Study: Samples of comet dust show mix of material in solar system - USATODAY.com (Site not responding. Last check: )
		Scientists expected the minute grains retrieved from a comet Wild 2 to be made up mostly of interstellar dust —; tiny particles that flow through the solar system thought to be from ancient stars that exploded and died.
		"People imagine that comets form in total isolation, which is definitely not true," said Don Brownlee, a University of Washington astronomer who is the principal scientist for the $212 million Stardust mission.
		A capsule carrying thousands of minuscule samples from comet Wild 2 returned to Earth last January after looping around the sun to capture the interstellar and comet debris and swooping past Wild 2 to scoop up dust.

		Comets are primarily composed of ice and dust, causing some astronomers to refer to them as "dirty snowballs." They typically move through the solar system in orbits ranging from a few years to several hundred thousand years.
		As they near the sun, the sun's heat melts the comet's ices and releases dust particles which are most evident as the comet's tail.
		The motion of asteroids is similar to that of comets in that the position must be plotted on a star chart over two or three days for motion to be detected.

		He described the comet as a somewhat bright telescopic object, but did not report it since he thought he was observing the comet Schmidt had found on July 2.
		Schjellerup remarked, "The comet is rather bright, the nucleus equalled a star of 7th magnitude." He added that at a magnification of 226x they saw a distinct extension in the direction of the sun, while the surrounding nebulosity was 3 arc minutes across.
		The comet was described as stellar with a magnitude of 17.5.
