Strange Weather Patterns On Uranus
2012-10-21 08:59:09

April Flowers for redOrbit.com — Your Universe Online New, exquisitely detailed, high-resolution images of Uranus show off its complex weather patterns and new features of the planet that scientists can't explain yet. Uranus, the seventh planet from the Sun, is an ice giant composed mainly of frozen methane, water, ammonia and hydrocarbons. In 1986, Voyager 2 passed by Uranus and returned the iconic image that most associate with the planet. This image showed a smooth, blue-green...

Uranus Bizarre Weather Revealed
2012-10-17 12:09:48

[ Watch the Video: What is Uranus? ] Lee Rannals for redOrbit.com - Your Universe Online Uranus is coming into more focus than ever with a new technique developed by astronomers and applied at the Keck Observatory. Astronomers reported at the American Astronomical Society's Division for Planetary Sciences meeting that they have taken high-resolution infrared images of Uranus, revealing detail of the planet's bizarre weather. The latest details of the seventh planet from the Sun...

Live Video Feed To Track Uranus And Harvest Moon Tonight
2012-09-29 04:29:25

Lee Rannals for redOrbit.com - Your Universe Online "I can see Uranus!" You could say that very phrase if you log on to Slooh Space Camera on Saturday night to get a glimpse of Uranus and the Harvest Moon. Slooh.com said it will be broadcasting live observatory feeds of Uranus and the full moon starting at 4:00 p.m. pacific time, 7:00 p.m. eastern. Uranus is the seventh planet from the Sun, and lies about 1.787 billion miles away. It takes 83 Earth years for Uranus to complete one...

Solar System Shaped By Stellar Shockwaves
2012-09-28 08:20:29

Lee Rannals for redOrbit.com - Your Universe Online Shockwaves emitted by our young sun in its early days would have caused the planets in our solar system to form, according to research presented at the European Planetary Science Congress. Astronomers modeled the movements of particles in fluids and gases in the gas cloud from which our Sun accreted. Their work suggests that during its early days, the Sun emitted a series of shockwaves that rippled out into the remaining material....

Lee Rannals for redOrbit.com - Your Universe Online Monday marked the 35 year anniversary of NASA's Voyager 2 spacecraft launching from Earth, and embarking on a venture to go where no spacecraft has gone before. The Voyager 2 spacecraft, and its twin Voyager 1, are still hurtling through space, on a path that is sending them outside of our Solar System. "Even 35 years on, our rugged Voyager spacecraft are poised to make new discoveries as we eagerly await the signs that we've...

Auroras Seen Dancing Around On Uranus
2012-04-13 12:47:09

Scientists have seen auroras dancing around above the giant ice planet Uranus by using the Hubble Space Telescope. The Uranian light show consisted of short-lived, faint, glowing dots, a show completely different than that seen on planet Earth. The researchers detected the luminous spots twice on the dayside of Uranus, which is the side that is visible to Hubble. Unlike auroras on Earth, the newly detected auroras on Uranus appear to only last a couple of minutes. Auroras are a...

Ice Giants Found To Have More Water Volume
2012-03-20 03:06:13

The idea of compressing water is foreign to our daily experience. Nevertheless, an accurate estimate of water´s shrinking volume under the huge gravitational pressures of large planets is essential to astrophysicists trying to model the evolution of the universe. They need to assume how much space is taken up by water trapped under high density and pressure, deep inside a planet, to calculate how much is needed of other elements to flesh out the planet´s astronomical image. In...

Voyager Instrument Cooling After Heater Turned off
2012-01-18 12:59:22

In order to reduce power consumption, mission managers have turned off a heater on part of NASA's Voyager 1 spacecraft, dropping the temperature of its ultraviolet spectrometer instrument more than 23 degrees Celsius (41 degrees Fahrenheit). It is now operating at a temperature below minus 79 degrees Celsius (minus 110 degrees Fahrenheit), the coldest temperature that the instrument has ever endured. This heater shut-off is a step in the careful management of the diminishing electrical power...

NASA's Voyager 1 spacecraft has entered a new region between our solar system and interstellar space. Data obtained from Voyager over the last year reveal this new region to be a kind of cosmic purgatory. In it, the wind of charged particles streaming out from our sun has calmed, our solar system's magnetic field has piled up, and higher-energy particles from inside our solar system appear to be leaking out into interstellar space. "Voyager tells us now that we're in a stagnation...

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...
