NASA has released global maps of six of the Saturnian moons. The system has been under the intense examination of the Cassini-Huygens mission for the past decade, and the completion of the global maps represents the end of one of the legendary spacecraft's key mission objectives. Almost all of the maps are whole, though there are currently parts of Iapetus unfinished, as well as a region of the north pole of Enceladus set to be filled in some time next year.  Read More

Jupiter's Great Red Spot may be caused by the sun and not some internal phenomenon as prev...

The Great Red Spot is the distinguishing feature that makes Jupiter one of the most easily recognizable planets in our solar system. Until recently, it was widely believed that this blemish was formed as a result of reddish-colored chemicals rising up from within the planet itself. However, using information obtained by analysis of data from the Cassini fly-by mission of Jupiter, researchers working at NASA's Jet Propulsion Laboratory have discerned that the planet's Great Red Spot may have more to do with the external action of the sun than some internal mechanism.  Read More

Having returned a vast number of incredible images of Saturn, her rings and her moons, NASA's Cassini spacecraft is reaching the final stage of its marathon mission. As such, and with the help of over 2,000 members of the general public, mission operators have selected a fitting name for the final maneuvers of the iconic spacecraft.  Read More

Data collected from observations recorded by NASA's Cassini mission has been used to propose ways to better understand the atmospheres of exoplanets. By studying the light of sunsets on Saturn’s satellite, Titan, scientists have shown how spectra are subtly altered when passing through a hazy atmosphere, thereby giving a greater insight into interpreting the spectral readings of the atmosphere of these distant worlds.  Read More

Images from NASA's Cassini spacecraft taken Apr. 15 hint at the formation of a new Saturnian moon. The icy object, believed to be only half a mile in diameter, recently formed in Saturn's outer rings and has been given the provisional name, Peggy.  Read More

With the use of its Cassini spacecraft and the Deep Space Orbiting Network, NASA has potentially discovered evidence for the presence of an ocean of liquid water locked away beneath the thick, icy crust of Saturn's moon, Enceladus.  Read More

If the midweek hump has you in a contemplative spirits, this stunning image of Earth as pictured by the Cassini spacecraft from Saturn, 898 million miles (1.44 billion kilometers) away, may offer a little context. The Earth and the Moon appear to be seemingly insignificant specks from the perspective of the spacecraft from its orbit around the gas giant, the second biggest planet in the Solar System. But as it turns out, Cassini is actually talking us up.  Read More

False-color images showing a Saturnian storm slowly dissipating after running into its own...

NASA’s Cassini probe witnessed a giant storm on Saturn that raced around the ringed planet, ran into its own tail, and consumed itself like the legendary Ouroboros – a snake that eats its tail. The storm, which at its peak was almost as wide as the Earth, lasted for 267 days and was marked by violent lightning bursts and an unusual rise in air temperature. This self-destructing storm is a phenomenon never seen before, and sheds new light on Saturn’s meteorology that could help with weather prediction on Earth.  Read More

It will soon be spring on Saturn ... and it will last for the next eight years or so. To celebrate the slow passing of the seasons of the giant ringed planet, NASA has released four real-color images sent back by the Cassini space probe. The images not only show the seasonal changes, but also the mysterious vortex recently discovered at the south pole of Saturn’s largest moon, Titan.  Read More

Findings at MIT suggest that Titan's geological phenomena may bear remarkably close simila...

After revealing the strong possibility of an underground liquid water ocean on Titan, further analysis of radar data collected by a flyby of the Huygens/Cassini spacecraft is now suggesting that, despite a dramatically different composition, Saturn's largest moon may share many of Earth's geological processes. By studying those features, exogeologists are beginning to answer some pressing questions on the forces that shaped Titan's geological past.  Read More
