Twenty years ago on February 14, NASA's Voyager 1 spacecraft had sailed beyond the outermost planet in our solar system and turned its camera inward to snap a series of final images that would be its parting valentine to the string of planets it called home. Mercury was too close to the sun to see, Mars showed only a thin crescent of sunlight, and Pluto was too dim, but Voyager was able to capture cameos of Neptune, Uranus, Saturn, Jupiter, Earth and Venus from its unique vantage point. These...

Toward the end of September, the sun will turn a spotlight on the asteroid Juno, giving that bulky lump of rock a rare featured cameo in the night sky. Those who get out to a dark, unpolluted sky will be able to spot the asteroid's silvery glint near the planet Uranus with a pair of binoculars. "It can usually be seen by a good amateur telescope, but the guy on the street doesn't usually get a chance to observe it," said Don Yeomans, manager of NASA's Near Earth Object Program Office at JPL....

In 1918, magician extraordinaire Harry Houdini created a sensation when he made a 10,000 pound elephant disappear before a mystified audience of over 5,200 at New York's famed Hippodrome theatre. But a vanishing pachyderm is nothing compared to the magnificent illusion to be performed by our solar system's own sixth rock from the sun on Aug. 11. On that day, ladies and gentlemen, boys and girls, children of all ages, the planet Saturn, with no help from either Jupiter or Uranus, will make its...

Scientists have reported new calculations that place Saturn's day at five minutes shorter than previously considered. A team of scientists from Oxford University and the University of Louisville has discovered that Saturn's day lasts just 10 hours, 34 minutes and 13 seconds. The new calculation shows that Saturn is rotating at a pace that is five minutes faster than previously estimated. The discovery may challenge prior observations about the planet's composition, researchers said in the...

The European Space Agency's Herschel and Planck satellites went into space Thursday aboard an Ariane 5 rocket from the French spaceport in French Guiana. The dual space telescopes were headed toward a spot called L2 -- the second Lagrange point -- where they will operate in different orbits. L2 is a local gravitational point that is fixed in the Earth-sun system and is situated on Earth's night side, the ESA said. It is an excellent location for both Herschel and Planck; it allows them to...

Some stars have it tough when it comes to raising planets. A new image from NASA's Spitzer Space Telescope shows one unlucky lot of stars, born into a dangerous neighborhood. The stars themselves are safe, but the material surrounding them -- the dusty bits of what might have been future planets -- can be seen blowing off into space. The hazard in this particular nook of space is a group of behemoth stars. Radiation and winds from the massive stars are wiping smaller, sun-like stars clean of...

Jupiter has a rocky core that is more than twice as large as previously thought, according to computer calculations by a University of California, Berkeley, geophysicist who simulated conditions inside the planet on the scale of individual hydrogen and helium atoms. The results were published Nov. 20 in Astrophysical Journal Letters. The simulation predict the properties of hydrogen-helium mixtures at the extreme pressures and temperatures that occur in Jupiter's interior, which cannot yet be...

170 light-years away from earth exists a particularly puzzling orbiting object. This object, 2M1207B, seems to be physically impossible. Nothing about it matches any established astronomical theory. Eric Mamajek of the Harvard-Smithsonian Center for Astrophysics announced in a press conference, "This is a strange enough object that it needs a strange explanation." During this press conference, the 211th meeting of the American Astronomical Society, astronomers announced that 2M1207B might in...

This series of images from NASA's Hubble Space Telescope shows how the ring system around the distant planet Uranus appears at ever more oblique (shallower) tilts as viewed from Earth - culminating in the rings being seen edge-on in three observing opportunities in 2007. The best of these events appears in the far right image taken with Hubble's Wide Field Planetary Camera 2 on August 14, 2007. The edge-on rings appear as two spikes above and below the planet. The rings cannot be seen...

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...

  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
