Comet Siding Spring will brush astonishingly close to Mars later this year – but UMD astronomers say it won't harm three spacecraft orbiting the Red Planet. Instead the spacecraft will give scientists an unprecedented close look at the comet as it nears the sun for the first time. (PRWEB) June 19, 2014 Comet Siding Spring will brush astonishingly close to Mars later this year – close enough to raise concerns about the safety of three spacecraft orbiting the Red Planet. But after...

Rosetta Comet Is Coming Alive

[ Watch The Video: ScienceCasts: Rosetta Comet Comes Alive ] Dr. Tony Phillips, Science@NASA A spacecraft from Earth is about to do something no spacecraft has ever done before: orbit a comet and land on its surface. Right now, the European Space Agency's Rosetta probe is hurtling toward Comet 67P/Churyumov-Gerasimenko. The spacecraft's mission is to study the comet at close-range as it transforms from a quiet nugget of ice and rock, frozen solid by years spent in deep space,...

Researchers from the Universities Space Research Association observed the comet 209P/LINEAR which was responsible for the recent Camelopardalids meteor shower of May 2014. Comets rarely come this close to Earth, making it an extraordinary opportunity to get images of the surface. Arecibo, Puerto Rico (PRWEB) May 29, 2014 The Arecibo Observatory planetary radar system observed periodic comet 209P/LINEAR from May 23 through May 27, 2014, finding it to be about 2.4 by 3 km kilometers (1.5 x...

Comet ISON Lives On In Scientific Data
2013-12-10 19:54:10

[ Watch the Video: Comet ISON - Gone But Not Forgotten ] Lee Rannals for redOrbit.com – Your Universe Online While the general public is disappointed about the outcome of comet ISON’s perihelion, scientists are thrilled in the data this object was able to bring to the community. Comet ISON made its closest approach to the sun on Thanksgiving Day, and predictions showed it had a 50/50 shot whether or not the comet would survive. Days after perihelion, scientists saw that only a...

Searching For What Is Left OF Comet ISON
2013-12-05 08:56:07

NASA Just prior to its closest approach to the sun on November 28, Comet ISON went through a major heating event, and likely suffered a major disruption. At this time, scientists are not sure how much of the comet survived intact. We may be seeing emission from rubble and debris in the comet's trail, along its orbit, or we may be seeing the resumption of cometary activity from a sizable nucleus-sized chunk of ISON. Most agree that up to 90 percent of ISON was destroyed, leaving...

Comet ISON Does Not Survive Perihelion, Only A Ghost Remains

[ Watch the Video: The Life And Times Of Comet ISON ] Lawrence LeBlond for redOrbit.com - Your Universe Online In true soap opera fashion, the enigmatic comet ISON has followed a somewhat tumultuous lifestyle. It has kept us on the edge of our seats like a good cliffhanger, and excited us when we least expected it to. Now after and up-and-down journey through the cosmos, ISON has seemingly met its match and it its fate has been sealed once and for all. Astronomers for over a year...

[ 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...

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...
