Elizabeth Zubritsky and Nancy Neal-Jones, NASA’s Goddard Space Flight Center A NASA-led team of scientists has created detailed 3-D maps of the atmospheres surrounding comets, identifying several gases and mapping their spread at the highest resolution ever achieved. [ Watch: HCN – Inner Coma Of C/2012 F6 (Lemmon) ] “We achieved truly first-of-a-kind mapping of important molecules that help us understand the nature of comets,” said Martin Cordiner, a researcher working in the...

redOrbit Staff & Wire Reports - Your Universe Online After a journey of more than six billion kilometers through the Solar System, the ESA’s Rosetta probe is closing in on comet 67P/Churyumov–Gerasimenko (67P), and with less than a week to go until its arrival, it recently managed to take the comet’s temperature for the first time and has captured images of a coma surrounding its nucleus. Rosetta, which lifted off from a European spaceport in French Guiana in March 2004, has...

meteor shower and a supermoon

April Flowers for redOrbit.com - Your Universe Online Amateur astronomers anxiously await the mid-August Perseid meteor shower every year. Typically occurring on the 11th, 12th and 13th of August, the meteor shower is one of the treats of the summertime sky. This year, that treat is being enhanced by a supermoon. [ Watch: ScienceCasts: Perseid Meteors Vs The Supermoon ] Though this is not the only supermoon this year, it is predicted to be the biggest, and brightest, full Moon we...

redOrbit Staff & Wire Reports - Your Universe Online New photos of 67P/Churyumov-Gerasimenko (67P/C-G) obtained by ESA’s Rosetta Probe reveal the comet has an extremely irregular shape and is likely a contact binary, meaning that it is comprised of two distinct parts that gravitate towards each other and ultimately form a single odd-looking body. Rosetta, which is on a historic mission to orbit and land on the comet, captured the image from a distance of 12,000km using its...

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
2014-06-04 03:39:31

[ 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

[ 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...

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...
