Saturn’s moon Mimas may have an underground ocean – or just a weird core

It wasn’t that long ago that Earth was thought to be the only place in the Solar System capable of having liquid water oceans, but now we know of several moons that do as well, including Europa and Enceladus, and likely Titan and Ganymede as well. In all these cases, the oceans are below ground, Continue Reading →

Space dust indicates ancient origin for Saturn’s rings

The origin of Saturn’s rings has been one of the most interesting puzzles in planetary science, and now new data from the Cassini spacecraft is helping to fill in the pieces, showing that the majestic ring system is very ancient, probably as old as Saturn itself.

Cassini at Saturn: 10 years of amazing planetary science and more to come

The Cassini mission to Saturn has been one of the most successful and exciting in all of space exploration history. That amazing spacecraft is now celebrating its 10th anniversary today orbiting the ringed planet, after having revolutionized our understanding of the Saturnian system, which is like another entire smaller-scale solar system. But there is still Continue Reading →

Looking at Uranus: Cassini spacecraft photographs another ‘pale blue dot’

The Cassini spacecraft, still in orbit around Saturn, has taken another “wow” photograph of something other than the ringed giant planet – the much more distant ice giant planet Uranus!

Has Cassini seen the birth of a new Saturnian moon?

Saturn has dozens of moons, ranging from the largest, Titan, which is larger than our own Moon, to small asteroid-sized objects. Now it seems that the Cassini spacecraft may have witnessed the formation of yet another moon, actually seeing the process as it is happening.

Image Gallery: Saturn and Enceladus

This image of Saturn from the Cassini spacecraft shows the planet with its rings edge-on, as a thin vertical line, against the massive gas giant planet itself. The shadows from the rings are on the left side of the planet, and if you look closely, the tiny watery moon Enceladus can be seen just in Continue Reading →

Image Gallery: the plumes of Enceladus

An amazing view of the water vapour plumes erupting from the “tiger stripe” fissures at the south pole of Saturn’s moon Enceladus. The plumes have been sampled and analzyed by the Cassini spacecraft and found to contain water vapour, ice particles, salts and organics. As just reported also, there is now evidence for a subsurface Continue Reading →

Beautiful new views of Saturn’s auroras

Auroras are one of the most beautiful natural phenomena on Earth, but they can be found on other planets in the solar system as well, notably the gas giants. New photos and video were released today, February 11, 2014, of just such displays on Saturn, which is already well known of course for its stunning rings and hexagonal Continue Reading →

What is this odd object in Saturn’s rings?

Saturn’s rings are one of the most phenomenal things ever seen in nature, and now there is a new puzzling little mystery in them called Peggy that scientists are trying to figure out.

Cassini’s best-ever view of Saturn’s amazing hexagon

The solar system is full of many planets and moons, each with their own unique characteristics and features, some of which have never been seen anywhere else. One such oddity is found on Saturn – a giant hexagon-shaped jet stream surrounding the planet’s north pole. It is a natural feature in Saturn’s atmosphere, although the Continue Reading →
