The Cassini-Huygens spacecraft has studied Titan for many years. But its tantalising discoveries about Saturn’s largest moon have led to new mysteries. One of those involves what seem to be wind-created sand dunes spotted by Cassini near the moon’s equator. These dunes are up to one hundred yards high, many miles in length, and point to the east. Climate simulations indicate that Titan’s near-surface winds, similar to Earth’s trade winds, blow toward the west. What’s going on?

saturn's rotation

Tracking the rotation speed of solid planets, like the Earth and Mars, is a relatively simple task: Just measure the time it takes for a surface feature to roll into view again. But giant gas planets Jupiter and Saturn are more problematic for planetary scientists, as they both lack measureable solid surfaces and are covered by thick layers of clouds, foiling direct visual measurements by space probes. Saturn has presented an even greater challenge to scientists, as different parts of this...

The biggest moon in our solar system has some big news to share: it has a huge, saltwater ocean underneath its crust!

Add Enceladus to the growing list of candidates that may be capable of supporting life, as an international team of researchers has discovered evidence of an active hydrothermal system on the icy Saturn moon that could be capable of supporting microbial life.

WASHINGTON, March 11, 2015 /PRNewswire-USNewswire/ -- NASA's Cassini spacecraft has provided scientists the first clear evidence that Saturn's moon Enceladus exhibits signs of present-day hydrothermal

Is Saturn's moon Iapetus a jedi or a sith? NASA would claim it's both.

One can only assume that NASA is tiring of building orbiters and rovers, because one of their newest projects is a new, unmanned submarine designed to explore the liquid hydrocarbon seas of Titan, the largest moon of Saturn, in a future mission.

Watch out Saturn, there's a new star in town. A huge star has been discovered with rings 200 times bigger and brighter than Saturn's, and a recent eclipse allowed for scientists to gather more intel on this galactic super star.

Scientists have paired NASA's Cassini spacecraft with the National Science Foundation's Very Long Baseline Array (VLBA) radio-telescope system to pinpoint the position of Saturn and its family of moons to within about 2 miles (4 kilometers).

Europa

The scientific community was a-buzz in late 2013, when NASA researchers reported that the Hubble Space Telescope had detected 120-mile high vapor plumes emanating from the south pole of Jupiter’s moon Europa.

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

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...
