Brett Smith for redOrbit.com - Your Universe Online A joint research effort between NASA and the European Space Agency has found proof that nitrogen within the atmosphere of Saturn's moon Titan came from conditions very similar to those that formed most of the ancient comets in the Oort cloud, according to a new report in the Astrophysical Journal Letters. The Oort cloud is a spherical cloud of predominantly icy space rocks believed to surround the Sun at a radius far outside the Solar...

ESA Expects The Unexpected As Rosetta Nears Comet Rendezvous
2014-06-20 09:49:28

April Flowers for redOrbit.com - Your Universe Online The European Space Agency's (ESA) Rosetta spacecraft is the first mission in history to attempt to rendezvous with a comet. The spacecraft will deploy the Philae lander to the surface of the comet and accompany it as it orbits the Sun. The comet in question is 67P/Churyumov-Gerasimenko, which is currently approximately 267,189 miles from the spacecraft. The Rosetta team released a series of images last May that detailed the extended...

Comet Siding Spring Won't Disrupt Martian Orbiters As It Makes Close Approach Of The Red Planet
2014-06-20 07:06:18

April Flowers for redOrbit.com - Your Universe Online Later this year, comet Siding Spring will have a very close brush with Mars. That brush will be so close, in fact, that it lead scientists to worry about the safety of the three spacecraft currently orbiting the planet. Some experts from the University of Maryland (UMD) have used a satellite mounted telescope to observe the "fresh" comet, however, and they find that it poses minimal danger to the Martian spacecraft. Instead, the...

Rosetta at Comet
2014-06-10 16:21:28

NASA Three NASA science instruments aboard the European Space Agency's (ESA) Rosetta spacecraft, which is set to become the first to orbit a comet and land a probe on its nucleus, are beginning observations and sending science data back to Earth. Launched in March 2004, Rosetta was reactivated in January 2014 after a record 957 days in hibernation. Composed of an orbiter and lander, Rosetta's objective is to arrive at comet 67P/Churyumov-Gerasimenko in August to study the celestial...

On the eve of the StarLight Festival, hosted by the AstronomyOutreach network in Big Bear California, Earth is set to smash into the debris fields from Comet 209P/LINEAR for the very first time, lighting up the night sky May 23rd/24th. Big Bear, CA (PRWEB) May 20, 2014 Perhaps you have seen a “falling star” streak across the night sky, and if so, it’s something memorable. So how about witnessing 100-400 meteor falls an hour or maybe even much more if predictions by experts are...

ESA's Rosetta Spacecraft Spies Comet Beginning To Form Its Tail
2014-05-16 11:42:34

Brett Smith for redOrbit.com - Your Universe Online The comet targeted for research by the European Space Agency’s Rosetta probe has begun to develop its tail as it zooms closer and closer to the Sun. The probe is maneuvering to align with the comet’s orbit this month and is slated to rendezvous with it in August. On Thursday, the ESA released a series of images showing comet 67P/Churyumov–Gerasimenko developing its tail, or coma. Taken between March 27 and May 4, the...

Upcoming Camelopardalid Meteor Shower Could Rival The Perseids

[ Watch the Video: ScienceCasts - NASA On The Lookout For A New Meteor Shower ] Brett Smith for redOrbit.com - Your Universe Online May isn’t exactly known for its meteor showers. In fact, this month’s Camelopardalid meteor shower, caused by dust from periodic comet 209P/LINEAR, has technically never even been seen before. However, astronomers have predicted that May 2014 could see a Camelopardalid meteor shower that rivals the year’s biggest display – the Perseids of August....

Halleys Comet Meteor Shower

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online As comets hurtle into the inner part of the solar system, the Sun’s radiation causes two tails to emerge. The first is primarily gas, vaporized by the heat of our star’s intense, warming rays. But while this glowing streak is what provides the visual imagery we normally associate with comets, it quickly fades as the comets moves across the solar system. In contrast, the second tail is formed by the pressure of the solar...

Fireball Flying Over Northern Russian City Caught On Vehicle Dash Cam

Lawrence LeBlond for redOrbit.com - Your Universe Online A suspected meteorite explosion has been recorded by citizens of the northern Russian city of Murmansk over the weekend. The fireball left a noticeable bright blue trail as it sped across the night sky at about 2:14 am (local time) on Saturday, before ending in explosion, according to multiple witnesses. There were no reports of damage during this weekend’s encounter, yet the fireball did raise some eyebrows due to its eerily...

Plant Material Stored In Impact Glass Could Reveal Much About Ancient Earth, Mars
2014-04-20 07:04:38

redOrbit Staff & Wire Reports - Your Universe Online The discovery of biodata encapsulated in molten glass resulting from asteroid and comet impacts millions of years ago not only provides information about the climate and life forms of the ancient Earth, but has also led to hopes that similar preserved organic compounds will be discovered on Mars. Fragments of leaves and other organic compounds were found lodged inside glass created by ancient impacts in Argentina by Brown...

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...

Solar System

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...
