Latest Saturn Stories
Scientists have long been intrigued by Titan because of the similarities it shares with Earth. Much like our planet, Titan has a seemingly layered structure, loosely similar to that of an onion.
While American folk singer Pete Seeger may not have considered Titan, the planet Saturn’s largest moon, as something unto which there is a season, it does seem that the moon has seen a type of turn or change in the seasons.
NASA announced on Monday its Cassini spacecraft has helped to discover a "video gamers' paradise" at Saturn.
A literal shot in the dark by imaging cameras on NASA's Cassini spacecraft has yielded an image of a visible glow from Titan, emanating not just from the top of Titan's atmosphere, but also - surprisingly - from deep in the atmosphere through the moon's haze.
NASA's Cassini spacecraft tracked the aftermath of a rare massive storm on Saturn, revealing disturbances in the planet's upper atmosphere long after the visible signs of the storm abated.
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.
Planetary scientists claim in a paper published in Icarus that Saturn's moons may have formed due to giant impacts.
What resembles a giant hot cross bun? According to radar images from NASA's Cassini spacecraft, a mysterious, nearly circular feature on Saturn's moon Titan does.
As the Cassini spacecraft hurtles around Saturn along its continuing mission, NASA announced the fifteen-year anniversary of the probe’s launch this week.
Cassini-Huygens Mission -- The Cassini unmanned space probe is intended to study Saturn and its moons. It was launched on October 15, 1997 and is estimated to enter Saturn's orbit on July 1, 2004. The mission is a joined NASA/ESA project. Cassini's principal objectives are to: -- determine the three-dimensional structure and dynamical behavior of the rings -- determine the composition of the satellite surfaces and the geological history of each object -- determine the nature and...
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 -- Uranus is the seventh planet from the sun. It is a gas giant. Physical characteristics Uranus is composed primarily of rock and various ices, with only about 15% hydrogen and a little helium (in contrast to Jupiter and Saturn which are mostly hydrogen). Uranus (and Neptune) are in many ways similar to the cores of Jupiter and Saturn minus the massive liquid metallic hydrogen envelope. It appears that Uranus does not have a rocky core like Jupiter and Saturn but rather...
Saturn's moon Phoebe -- Phoebe is the outermost of Saturn's known moons. Phoebe is almost 4 times more distant from Saturn than its nearest neighbor (Iapetus). It was discovered by William Henry Pickering in 1898. Most of Saturn's moons have very bright surfaces, but Phoebe's albedo is very low (.06), as dark as lampblack. All of Saturn's moons except for Phoebe and Iapetus orbit very nearly in the plane of Saturn's equator. Phoebe's orbit is retrograde, inclined almost 175, and is...
