The joint NASA/ESA mission Cassini-Huygens, currently in orbit around Saturn, has recently beamed back some amazing photos of a beautiful geyser eruption that took place on the moon Enceladus. The experts who investigated the images say that the emissions consisted mainly of water vapors, bringing further proof that ... |

Recent images of some of Saturn's moons have revealed strange patches of color on the surface of the five innermost natural satellites, Mimas, Enceladus, Tethys, Dione, and Rhea. Some of the unusual patterns have been seen before during previous flights, but others are totally new, the investigators for the miss... |

The image most of us have of Saturn is that of a gas giant closely surrounded by its rings, which are very thin, yet very wide. Now, astronomers prove us wrong, showing that the planet indeed has another, massive ring around it, which extends as much as 13 million kilometers away from it, around the moon Phoebe. This... |

After more than seven years of efforts poured into this initiative, experts can now finally boast the first geological map of Jupiter's moon Ganymede. This is only the third moon in the solar system to get such an “honor,” in addition to the Moon, and Jupiter's cratered Callisto. The detailed do... |

Between 1949 and 1961, the comet 147P/Kushida-Muramatsu was considered to be a moon of Jupiter. The large gas giant captured the celestial body in an irregular orbit around it, and its influence only became dim enough to let the comet escape after about 12 years of “captivity.” Dr. David Asher will presen... |

Ever since the 17th century, when Italian astronomer Galileo Galilei discovered that Saturn had rings around it, astronomers and astrophysicists have been trying to come up with a plausible explanation for how they were formed and why. To this day, the answer has eluded them, and each new scientific find about the pl... |

Saturn's moon Enceladus is, in many aspects, one of the most peculiar celestial bodies in the solar system. Once regarded as nothing more than a ball of frozen ice and dust, it revealed itself in 2006 to be still active, and potentially even harboring liquid water underneath the surface. Additionally, its weird ... |

Some 234 years before the planet was officially found, Galileo may have made the earliest observations of Neptune, a new study of the famous astronomer's diary and notebooks reveals. Professor David Jamieson, the head of the University of Melbourne School of Physics, made the astonishing claim, after studying in... |

Every now and then, the moons of Saturn align themselves in such a manner that they either throw their shadows on the surface of the planet, making them look like they're chasing each other, or they cast them on the giant planet's rings, creating vertical structures that are beautiful to look at. One such i... |

Jupiter's ice-covered moon Europa is one of the safest bets in the Universe of finding life, or, otherwise put, it's one of the few places other than the Earth that astronomers believe it's able to sustain life to some extent. The experts are not talking about mammals, or other higher creatures, but ab... |

Over the recent years, an increased number of concepts referring to the “handedness of life” have begun to appear, and in areas of research few would have thought possible. For instance, astronomers are now working with scientists on the creation of a new means of looking for life on other planets, throug... |

The Hubble Space Telescope proves, indeed, to be invaluable for both NASA and ESA, as evidenced by one of its recent snapshots of Saturn, which has been photographed in a rare alignment with four of its moons. The configuration only occurs once in 14 to 15 years, and the last time astronomers and other observers were... |

Not many people know that the Red Planet, which has been intensely-scrutinized over the past few years with several rovers and orbiters, also has two very small moons, Deimos and Phobos. Discovered in 1877 by Asaph Hall, the two celestial bodies orbiting Mars are thought to be captured asteroids that can no longer es... |

Despite the fact that Jupiter has a number of approximately 63 named satellites, only four of them are generally referred to as the planet's moons. These four celestial bodies, Io, Europa, Ganymede and Callisto, are also dubbed the Galilean Moons, in honor of the great Italian astronomer. Now, researchers have e... |

Every time you point the telescope towards Jupiter you'll most certainly see one of its four large satellites discovered by Galileo in the early 1600s. Usually, two or three of the moons can be easily spotted and sometimes even all four of them. On a small telescope, Jupiter's moons appear as small stars sh... |

Such strange flying-saucer-shaped objects mostly common in Saturn's rings have puzzled scientists. It appears that they form from gathering particles of ice and dust from the rings, much in the same way planets form by buiding up matter from accretion disks spinning around stars, and could provide us with valuab... |
