New Images Of Comet ISON

[ Watch the Video: SOHO Sees Comet ISON Appear ] NASA As Comet ISON heads toward its closest approach to the sun — known as perihelion — on Nov. 28, 2013, scientists have been watching through many observatories to see if the comet has already broken up under the intense heat and gravitational forces of the sun. The comet is too far away to discern how many pieces it is in, so instead researchers carefully measure how bright it is, which can be used to infer its current state....

How Comet ISON Is Spending Thanksgiving With The Sun: Exclusive

[ Watch the Video: SOHO Sees Comet ISON Appear ] Lee Rannals for redOrbit.com - Your Universe Online Comet ISON will be spending Thanksgiving Day within the sun’s grasp and it is this moment and those leading up to it that will help define the comet’s future. The journey of Comet ISON has been a cinematic one, particularly because its existence was not even known until September of last year. Since then, the comet has garnered international attention from amateur and professional...

Comet ISON May Or May Not Put On A Show

[ Watch the Video: ISON Keeps Giving Us The Run-Around ] Alan McStravick for redOrbit.com - Your Universe Online I’ve been nerding out for most of the year, since Comet ISON first came on my radar, so to speak. Back in February, I wrote a piece for redOrbit detailing the discovery of a comet so magnificent that its show was going to be the stuff of legend. And then in July, redOrbit’s Brett Smith tried to rain on my astral parade when he reported on the diminished expectations...

NASA Science Comet ISON is now inside the orbit of Earth as it plunges headlong toward the sun for a fiery close encounter on Nov. 28th. Although the comet is not yet as bright as many forecasters predicted, the comet is putting on a good show for observatories around the solar system. NASA spacecraft and amateur astronomers alike are snapping crisp pictures of the comet's gossamer green atmosphere and filamentary double-tail. Because ISON has never passed through the inner solar system...

Approaching Comets ISON And Encke Pose For NASA's MESSENGER
2013-11-14 14:24:57

Lee Rannals for redOrbit.com - Your Universe Online NASA’s MESSENGER spacecraft helped snag a few images of comets ISON and Encke as they are making their way closer to Mercury and the Sun, where they will be much brighter and more readily visible to amateur astronomers. Comet ISON was discovered in September 2012 by amateur astronomers in Russia using a 16-inch telescope that is part of the International Scientific Optical Network. Astronomers predict ISON will be flying within...

Comet ISON Photo Contest NSF

[ Watch the Video: Get Ready For The Comet ISON Photo Contest ] Lee Rannals for redOrbit.com - Your Universe Online The National Science Foundation (NSF), along with Astronomy and Discover magazines are offering $2,500 to whomever takes the best photo of Comet ISON. Contest organizers said they are asking photographers to get a creative shot of the highly anticipated comet this fall, starting now through January 15, 2014. “We challenge photographers, amateur and professional, to...

Amateur Astronomers Can Now Observe An Approaching Comet ISON
2013-09-25 12:35:52

Lee Rannals for redOrbit.com - Your Universe Online Comet ISON is getting closer and closer to making its close encounter with the sun on Thanksgiving Day, and amateur astronomers are gearing up to take every opportunity they can to observe the celestial object between now and then. The comet's brush with the sun on November 28 could either turn it into a sight for all to see, or destroy the icy visitor. So while we hope for the best, astronomers still should be taking every advantage...

Comet ISON Still On Track For Fall Spectacle: Exclusive

[ Watch the Video: Don't Give Up On Comet ISON Just Yet ] Lee Rannals for redOrbit.com - Your Universe Online Remember when we, and everyone else in the media circuit, reported about how Comet ISON was fizzling out? Well, forget about it, because a very reliable source tells redOrbit that the comet is still on track to potentially provide a spectacular show in the night sky. Comet ISON has been closely watched by several astronomers over the past year with great anticipation, but...

Comet Activity Starting Up Early Ahead Of 2014 Rosetta Mission
2013-08-20 13:48:03

Lee Rannals for redOrbit.com - Your Universe Online Comet Churyumov-Gerasimenko, a 2014 visitor to our neck of the woods, will be emitting gas and dust earlier than expected, according to a new study by the Max Planck Institute for Solar System Research (MPS). The European Space Agency's (ESA) Rosetta spacecraft will be arriving at comet Churyumov-Gerasimenko next year, and two months after it starts its approach, the comet will start showing activity. Researchers say the comet's...

Comet ISON Starting To Fizzle Out
2013-08-20 04:23:25

[ Watch the Video: ScienceCasts: Comet ISON to Fly By Mars ] Lee Rannals for redOrbit.com - Your Universe Online New observations of the highly anticipated Comet ISON have shown this year's fall spectacle might not be as spectacular as we hoped. According to Sky & Telescope, amateur imager Bruce Gary in Arizona has become the first astronomer to pick up Comet ISON after it was hidden behind the Sun for a two-and-a-half month period. Gary pointed his 11-inch telescope about six...

Jean Elias Benjamin Valz was born on May 27, 1787 in Nimes in France. He was formally trained as an engineer, but he became intrigued with astronomy, specifically comets, after witnessing the return of the Comet Encke. Before leaving his home to become the Director of the Marseille Observatory, he built a private observatory in it. He theorized that abnormalities in the orbit of Halley's Comet could be explained by a planet beyond Uranus. Scientist would later discover this planet and...

Comet -- A comet is a small body from the outer reaches of the solar system similar to an asteroid but composed of ice. Often described as "dirty snowballs," they are composed largely of carbon dioxide ice, methane ice, and water ice with a mixture of dust and small stony aggregates mixed in. Comets are thought to be small pieces of debris left over from the formation of the solar system, representing a sample of the original composition of the nebula that condensed to form the Sun and all...

Halley's Comet -- Comet Halley, more generally known as Halley's Comet after Edmond Halley, is the best-known and the brightest of the "short-period" comets from the Kuiper belt that visit the inner solar system in years or decades-long orbits rather than the millennia of comets from the Oort Cloud. Early History Having perceived that the elements of the comet of 1682 were nearly the same as those of two comets which had appeared respectively in 1531 and 1607, Halley concluded that...

Comet Encke -- Because of its proximity to the Sun and its stable orbit, comet Encke is probably one of the most evolved comets that still remains active. It may represent a transition object between an active comet and the defunct comets that are thought to make up a significant percentage of the near-Earth asteroid population. The orbit of comet Encke is very stable both in its size and orientation because it can pass no closer to Jupiter than about 0.9 AU. This orbital stability...
