As Seen By Rosetta: Comet Surface Variations

NASA/ESA A new image of comet 67P/Churyumov-Gerasimenko shows the diversity of surface structures on the comet's nucleus. It was taken by the Rosetta spacecraft's OSIRIS narrow-angle camera on August 7, 2014. At the time, the spacecraft was 65...

Dr. Tony Phillips, Science@NASA On October 19, 2014, Comet Siding Spring will pass by Mars only 132,000 km away - which would be like a comet passing about 1/3 of the distance between Earth and the Moon. The nucleus of the comet won't hit Mars, but there could be a different kind of collision. "We hope to witness two atmospheres colliding," explains David Brain of the University of Colorado's Laboratory for Atmospheric and Space Physics (LASP). "This is a once in a lifetime event!"...

New exhibit explores planetary science through interactive multimedia and hands-on experiences. Newark, NJ (PRWEB) August 13, 2014 What exactly are asteroids, comets and meteorites, and where do they come from? What can they tell us about Earth and the origins of our Solar System? The Newark Museum’s upcoming exhibition Great Balls of Fire! Comets, Asteroids, Meteors explores recent discoveries and cutting-edge science relating to these incredible objects. It opens on October 1 and runs...

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...

NASA and ESA Close up detail focusing on a smooth region on the ‘base’ of the ‘body’ section of comet 67P/Churyumov-Gerasimenko. The image was taken by Rosetta’s Onboard Scientific Imaging System (OSIRIS) on August 6, 2014. The image clearly shows a range of features, including boulders, craters and steep cliffs. The image was taken from a distance of 80 miles (130 kilometers) and the image resolution is 8 feet (2.4 meters) per pixel. The three U.S. instruments aboard the...

redOrbit Staff & Wire Reports - Your Universe Online Following a decade-long journey that spanned more than six billion kilometers through space, the ESA’s Rosetta probe has arrived at comet 67P/Churyumov-Gerasimenko, officially making it the first mission to ever successfully complete such a rendezvous. Rosetta, which launched from a European spaceport in French Guiana on March 2, 2004, arrived at 67P early Wednesday morning, the ESA reported. The satellite will now escort the...

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...

Dwayne Brown, NASA Jet Propulsion Laboratory NASA is taking steps to protect its Mars orbiters, while preserving opportunities to gather valuable scientific data, as Comet C/2013 A1 Siding Spring heads toward a close flyby of Mars on Oct. 19. The comet's nucleus will miss Mars by about 82,000 miles (132,000 kilometers), shedding material hurtling at about 35 miles (56 kilometers) per second, relative to Mars and Mars-orbiting spacecraft. At that velocity, even the smallest particle --...

Preston Dyches, Jet Propulsion Laboratory Surface structures are becoming visible in new images of comet 67P/Churyumov-Gerasimenko taken by the scientific imaging system OSIRIS onboard the European Space Agency's Rosetta spacecraft. The resolution of these images is now 330 feet (100 meters) per pixel. One of the most striking features is currently found in the comet's neck region. This part of 67P seems to be brighter than the rest of the nucleus. As earlier images had already shown,...

Elizabeth Landau, NASA Jet Propulsion Laboratory Comet C/2013 UQ4 (Catalina) has been observed by NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft just one day after passing through its closest approach to the sun. The comet glows brightly in infrared wavelengths, with a dust tail streaking more than 62,000 miles (100,000 kilometers) across the sky. Its spectacular activity is driven by the vaporization of ice that has been preserved from the time of planet...

A Shubunkin is a type of single-tailed goldfish with calico coloration, a combination of orange, white, black, red, and blue markings, blue being the most desired. They are similar to the common goldfish and the comet goldfish. Also called speckled goldfish, harlequin goldfish, calico goldfish, and coronation fish, they were developed in Japan about a hundred years ago by crossing calico fantails with single-tailed goldfish to produce a hardy, able swimmer with bright colors. There are...

A Fantail goldfish is a standard "fancy" type of goldfish. It has a dual-lobed tail, unlike its cousin the common or comet. Its fins can be different sizes, ranging from 1-3 in or more in length. A typical fantail has paired fins, including anal fins, a single dorsal fin, and a round, pointed body shape. It can range in color, from bronze (known as chocolate), orange, red, calico, and mixes of the colors. It is the third hardiest of the fancy goldfish with Comet first and Shubunkin second,...

The Comet is a commonly kept form of goldfish, the only type to have originated in the United States. They first appeared in the ponds of the Fish Commission in Washington in the early 1880s. Hugo Mullertt was the first person to bring the Comet goldfish to the market in a large quantity. Characterized by a long, tall, flowing tailfin they can be differentiated from the common goldfish, although otherwise they are very similar. Both of these varieties are quite hardy and will do well in...

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...

The Solar System refers to the area in space that is dominated by our own Sun. It is comprised of the Sun and its associated astronomical objects that are held in its gravitational orbit. The Solar System was formed as a result of the collapse of a giant molecular cloud approximately 4.6 billion years ago. The mass of this system is located almost entirely in the Sun. Apart from the Sun, a high percentage of the remainder of the system’s mass is located in the eight solitary planets that...
