Taking advantage of a period of increased solar activity – in November 2011 – astronomers operating the Hubble Space Telescope took these two images of Uranus, which provide some of the most detailed views ever obtained of auroras taking place on this planet. The fact that the intensity and brightness of... |

Recent studies trying to establish what exactly tilted Uranus's orbit to a 98-degree angle have reawaken a great deal of interest in the ice giant. Now, experts are proposing a new mission to the celestial body, in hopes of unlocking more of its many mysteries.
The idea is not new. Many such missions were pr... |

According to the conclusions of a new scientific study, it would appear that Uranus got such a tilted orbit after being subjected to repeated impacts from comets. In the past, astronomers believed that only a single, devastating blow was sufficient to tilt the massive gas giant.
In addition to providing a better ... |

Astronomers have been struggling to explain numerous odd properties displayed by Mercury and Uranus for many years now, but leading theories were just discredited over the past few days. Now, astronomers begin to search for new explanations of what actually happened. This line of inquiry is very difficult to push f... |

NASA is proud to announce that its New Horizons spacecraft has finally passed the orbit of Uranus, on its long trek to Pluto, one of the farthest planets in the solar system. The probe is due to reach its destination sometime in 2015, mission plans indicate.
This major mission milestone was reached on Saturday, Ma... |

According to the latest decadal report released by the National Research Council (NRC), the Red Planet and the Jovian moon Europa should be the highest priorities on the NASA agenda for the next 10 years. Expeditions there should be conducted as soon as possible. While a lot of ink has been spilled explaining why Mar... |

A quarter of a century ago, a NASA spacecraft flew past one of the most mysterious bodies in the solar system, the gas giant Uranus. The Voyager 2 spacecraft, on its way to exit the heliosphere, took the only close-up images of this planet and its moons.The mission, which is still ongoing, is managed by experts at th... |

After the Perseids in August, September comes with the autumn constellations, brought by the mythical winged horse Pegasus.The September constellations have few or no bright stars at all, not even Pegasus, which is one of the largest constellations in area.The star pattern that is most obvious to the naked eye is the... |

Astronomers say that August 20 will mark a very special day in their calendars, as the moment when the gas giant Neptune will complete its first orbit around the Sun, since being discovered back in 1846.In two days, the planet will be in opposition, which means that it will be on the same straight line as the Earth a... |

One of the things that have always fascinated astronomers about Uranus, the seventh planet from the Sun, is the fact that its axis of rotation is tilted sideways, to a large extent. In fact, it nearly reaches the plane of its revolution around the star, which is something unique to the ice giant. After the planet sta... |

Just before 2006, Pluto was still considered the most remote planet in the solar system. However, due to the discovery of a series of objects that had similar sizes and characteristics to that of Pluto, the object has been demoted from its status of planet to that of Kuiper belt object, or minor planet. Currently, th... |

The configuration of the solar system as observed today poses some serious questions about how the planets might have evolved from the protoplanetary disk spinning around the Sun, as current models cannot yet explain how a planet the size of Jupiter could have formed in only a few million years, while predictions reg... |

As the gas giant presents a tilt of 98 degrees from its orbit plane, during the solstice the poles point directly towards the Sun, triggering some extreme changes in solar illumination, seen in all the bodies in the solar system. This usual inclination presents great importance for planetary astronomers such as Heidi... |

This week, you will be able to see two of the gas giants in the night sky. With the moon out of the way, and a pair of binoculars, Uranus and Neptune will be well in your reach. Normally, most people can see the five brightest planets, but there is still a sixth planet that can't be observed without any optical ... |

Diamonds are known to form on Earth under very specific conditions, like exposure of carbon-bearing materials to high pressure, ranging approximately between 45 and 60 times normal atmospheric pressure, conditions that can be found in the lithospheric mantle below relatively stable continental plates and at the site ... |

Astronomers have received pictures showing two of Saturn' 27 moons, one passing in front of the other. This is considered very important for scientific calculations, as it is the only way that the mass of the moons can be approximated.With the help of the Faulkes Telescope South in Australia, astronomers observ... |
