Chariklo
2014-03-27 03:37:28

[ Watch the Video: Artist’s Impression of Ring System Around Chariklo ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers writing in the journal Nature say they have observed a minor planet which contains two rings of ice and pebbles for the first time. Chariklo sits about 1.2 billion miles out in the solar system between Saturn and Uranus, and the minor planet, or asteroid, has been known about for many years. However, this is the first time astronomers discovered...

Mystery Of Troposphere Warming Solved
2013-12-10 14:44:32

Lee Rannals for redOrbit.com - Your Universe Online A long-standing mystery surrounding unusual warming of planetary atmospheres is not just exclusive to our solar system, but is most likely universal, according to a paper published in the journal Nature Geoscience. In 1902 a scientist named Léon Teisserenc de Bort found a point in Earth’s atmosphere where the air stops cooling and begins growing warmer. This finding was surprising considering scientists knew that as you climb in...

diamonds on Jupiter and Saturn

[ Watch the Video: Are There Diamonds On Saturn And Jupiter? ] Lee Rannals for redOrbit.com - Your Universe Online Scientists speaking at the Division for Planetary Sciences of the American Astronomical Society say that Saturn and Jupiter may hold what many consider to be the key to a woman's heart: Diamonds. And lots of them. A team from the California Specialty Engineering and the University of Wisconsin, Madison said that Jupiter and Saturn could contain solid diamonds in their...

Methane Secrets Hold Key To Understanding Planetary Interiors
2013-09-12 14:28:33

Lee Rannals for redOrbit.com - Your Universe Online Researchers, publishing a paper in the journal Nature Communications, say their study on methane's secrets will help scientists better understand the chemistry of planetary interiors. Hydrocarbon methane (CH4) is one of the most abundant molecules in the universe, but its behavior under the conditions found in planetary interiors is poorly understand due to contradictory information from various modeling studies. Studying various...

Trojan Asteroids Are More Common Than Previously Believed
2013-08-30 05:06:06

[ Watch the Video: QF99 Motion Animation ] April Flowers for redOrbit.com - Your Universe Online The first Trojan asteroid sharing the orbit of Uranus has been discovered by University of British Columbia astronomers who believe the asteroid - 2011 QF99 - is part of a larger-than-expected population of transient objects temporarily trapped by the gravitational pull of the solar system's giant planets. Trojan asteroids share the orbit of a planet and occupy stable positions known as...

Voyager Celebrates 36 Years In Space
2013-08-20 15:40:23

Lee Rannals for redOrbit.com - Your Universe Online Thirty-six years ago NASA launched one of the longest missions in the space agency's history, the Voyager 2. The Voyager 2 spacecraft is a sister spacecraft of the Voyager 1 and was designed to explore not only planets like Jupiter, Saturn, Uranus and Neptune, but also the edge of our Solar System. Voyager 2 was able to give NASA an up-close look at Saturn and its moons. The 36-year-old spacecraft made its first flyby of Jupiter...

Asteroids Found To Have Similar Orbit To Uranus
2013-06-19 04:44:21

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online In 2006, Uruguayan astronomer Tabaré Gallardo provided evidence that two asteroids, Crantor and 2000 SN331, had orbital periods similar to that of the planet Uranus — roughly 84 Earth-years. Now, some seven years later, researchers Carlos de la Fuente Marcos and Raúl de la Fuente Marcos, at the Complutense University of Madrid (UCM), have confirmed that not two, but three large asteroids...

Charting Massive Winds On Gas Giants Of The Outer Solar System
2013-05-17 07:51:59

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Predicting the weather is difficult. With varying pressures, planetary rotation and various other factors, weather systems on Earth border on chaos. But, believe it or not, predicting the weather on the third rock from the sun is rather straightforward compared to predicting the atmospheric motions of the gas giants that lay beyond the asteroid belt. The primary reason is that, unlike Earth, the Jovian worlds do not have...

Historian Says Sir William Herschel May Not Be A 'Sir' At All
2013-04-05 15:48:24

Lee Rannals for redOrbit.com — Your Universe Online A paper written by the historian Michael Hoskin and published in the Journal for the History of Astronomy claims Sir William Herschel may not be a "Sir" after all. Hoskin says that William and John Herschel were both made a knight of the Royal Hanoverian Guelphic Order, an event that typically leads to someone earning themselves the title of "Sir." However, the historian said they were in fact not given the "Sir" titles at all....

With its 2160 liters of liquid helium about to run out, the Herschel Space Observatory will, by the end of March, become just another piece of space junk. In January´s Physics World, Steve Eales, a University of Cardiff astronomer who leads one of the telescope´s largest surveys, explains how this space facility has advanced our understanding of star and galaxy formation. Submillimeter wavelength astronomy -- the kind of astronomy that the European Space Agency´s Herschel...

Gas Giant
2004-10-19 04:45:41

Gas Giant -- A gas giant is a generic astronomical term invented by the science fiction writer James Blish to describe any large planet that is not composed mostly of rock or other solid matter. Gas giants may still have a solid core - in fact, it is expected that such a core is probably required for a gas giant to form - but the majority of its mass is in the form of gas (or gas compressed into a liquid state). Unlike rocky planets, gas giants do not have a well-defined surface. There...

Planet Neptune -- Neptune is the eighth planet from the sun. It is a gas giant. Orbiting so far from the sun, Neptune receives very little heat. Its 'surface' temperature is -218 degrees Celsius (below zero). However, the planet seems to have an internal source of heat. It is thought that this may be leftover heat generated by infalling matter during the planet's birth, now slowly radiating away into space. Neptune's atmosphere has the highest wind speeds in the solar system, up to...

Uranus' moon Sycorax -- Sycorax is a moon of Uranus. It was named after a witch living on an island in William Shakespeare's play The Tempest. Its orbital radius is approximately 12.2 million km from Uranus and is about 160 km in diameter, but this size estimate is based on the moon's apparent brightness and the assumption that it has an albedo of about 0.07. Its orbit is retrograde and highly inclined. Sycorax's composition is probably a mixture of rock and ice, and its unusually...

Uranus' moon Caliban -- Caliban is a moon of Uranus, named after Caliban, the character in William Shakespeare's play The Tempest. Caliban was discovered on September 6 - September 7, 1997 by Brett Gladman, Phil Nicholson, Joseph Burns, and JJ Kavelaars using the 200-inch Hale telescope; they also discovered the moon Sycorax at the same time. ----- Discovery Discovered by Brett Gladman Discovered in 1997 Orbital characteristics Semimajor axis 7.1106 km Eccentricity...

Uranus' moon Oberon -- Oberon is the name of the outermost of the major moons of the planet Uranus; discovered on January 11, 1787 by William Herschel. All of the moons of Uranus are named for characters from Shakespeare or Alexander Pope. Names for the first four discovered moons of Uranus (Oberon, Titania, Ariel, Umbriel) were given by John Herschel, the son of William. Oberon was named after Oberon, the king of the Faeries in A Midsummer Night's Dream. Oberon is composed of...
