    I didn’t notice it with the naked eye, but as soon as the time exposure ended and I looked at the camera’s back display, there it was — Saturn riding barebacked on the Galactic Dark Horse! The horse, more of a prancing pony, is a collection of dark nebulae in the southern sky beautifully placed for viewing on late June evenings. The Dark Horse is part of the Great Rift, a dark gap that splits the band of the Milky Way in half, starting at the Northern Cross and extending all the way down to the “Teapot” of Sagittarius in...

    he Cassini spacecraft is nearing the end of its lifespan. This September, after spending the past twenty years in space – twelve and a half of which were dedicated to studying Saturn and its system of moons – the probe will be crash into Saturn’s atmosphere. But between now and then, the probe will be making its “Grand Finale” – the final phase of its mission where it will dive between the planet and its rings 22 times. In addition to exploring this region of Saturn (something no other mission has done), the probe will also be using this opportunity...

    'The region, in shadow for the first part of the Cassini mission, now enjoys full sunlight, which enables Cassini scientists to directly image it in reflected light.' ... 'Around it swirl the clouds, driven by the fast winds of Saturn.' Although the poles of Saturn are at the center of all of this motion, not everything travels around them in circles. Some of the jet-stream patterns, such as the hexagon-shaped pattern seen here, have wavy, uneven shapes. The famous hexagon shape itself circumscribes the northern polar vortex – seen as a dark spot at the planet’s pole in the above...

    Enceladus’ south pole is wounded, bleeding heat and water. Its injury may have come from a huge rock smashing into this frigid moon of Saturn less than 100 million years ago, leaving the area riddled with leaky cracks. The region near Enceladus’ south pole marks one of the solar system’s most intriguing mysteries. It spews plumes of liquid from an interior ocean, plus an enormous amount of heat. The south pole’s heat emission is about 10 gigawatts higher than expected – equivalent to the power of 4000 wind turbines running at full capacity. The rest of the moon, though, is...

    NASA on Thursday released pictures of Pan, one of Saturn's many moons, and its distinctive shape is drawing comparisons to flying saucers and stuffed pasta. The images of the moon come courtesy of NASA's Cassini spacecraft, and reveal the UFO-like form of the tiny satellite, which has an average radius of just 8.8 miles. Cassini's Twitter account tweeted a gif showing the raw images. ... According to NASA's website, Pan's strange shape comes from what is called an equatorial ridge, a characteristic it shares with one of its sister moons, Atlas. The ridge has formed over the course of Pan's...

    Here's Our Best Look Yet at Saturn's 'UFO' Moon Adorned with a thin band of icy ring particles, the small moon Pan inspires comparisons to alien spacecraft, walnuts, and even ravioli. View Images One of Cassini's new views of Saturn's moon Pan. Photograph by NASA/JPL-Caltech/Space Science Institute By Nadia Drake PUBLISHED March 9, 2017 There’s a tiny “flying saucer” orbiting deep within Saturn’s rings, and a NASA probe has just gotten its most impressive look yet at the strange object. The saucer is actually a little moon called Pan, and NASA’s Cassini spacecraft captured its distinctive shape on March 7...

    This new picture from NASA's Cassini probe shows off the peculiarity of Daphnis, a moon so tiny it wasn't discovered until 2005. It's just 8 kilometres (5 miles) across, and irregularly shaped, which gives it a wobbly orbit. ... The Keeler gap is just 42 kilometres (26 miles) wide, and Daphnis' distance varies from Saturn by about 9 kilometres (5.6 miles), while it moves up and down by about 17 kilometres (10.5 miles). This eccentricity, and Daphnis' gravity, causes peaked waves to form on the edges of the gap, in both vertical and horizontal directions. In this new image, taken...

    New footage released by Nasa shows exactly what it looks like to land on an alien world. It may seem like stuff of science fiction, but the scenes in the new video happened in real life, 12 years ago. The stunning video was captured when the space agency’s Huygens probe descended onto the mysterious world of Titan, Saturn’s biggest moon.
  • Planetary Rings Defy Long Ages

    11/02/2016 11:05:40 AM PDT · by fishtank · 13 replies
    Models of the origin of planetary rings are simulations based on fictions. Real physics cannot keep them billions of years old. Theory vs Realism Researchers at Kobe University claim to have an explanation for planetary rings, Science Daily reports. Their supercomputer model accounts for the difference in composition of Saturn’s icy rings, compared to the rocky rings at Uranus and Neptune. The model, however, published in Icarus, relies on two doubtful assumptions. One is the Late Heavy Bombardment (LHB), which we reported on 9/13/16 is coming under fire. It could be a fiction based on poor data analysis of lunar...

    Centaurs are a population of objects within our Solar System that behave as both comets and asteroids (hence why they are named after the hybrid beasts of Greek mythology). 10199 Chariklo is the largest known member of the Centaur population, a possible former Trans-Neptunian Object (TNO) which currently orbits between Saturn and Uranus. The rings around this asteroid were first noticed in 2013 when the asteroid underwent a stellar occultation. This revealed a system of two rings, with a radius of 391 and 405 km and widths of about 7 km 3 km, respectively. The absorption features of the rings...

    Explanation: What's that over Paris? Cirrus. Typically, cirrus clouds appear white or gray when reflecting sunlight, can appear dark at sunset (or sunrise) against a better lit sky. Cirrus are among the highest types of clouds and are usually thin enough to see stars through. Cirrus clouds may form from moisture released above storm clouds and so may herald the arrival of a significant change in weather. Conversely, cirrus clouds have also been seen on Mars, Jupiter, Saturn, Titan, Uranus, and Neptune. The featured image was taken two days ago from a window in District 15, Paris, France, Earth. The...

    Explanation: What's older than these ancient trees? Nobody you know -- but almost everything in the background of this picture. The trees are impressively old -- each part of the Ancient Bristlecone Pine Forest located in eastern California, USA. There, many of the oldest trees known are located, some dating as far back as about 5,000 years. Seemingly attached to tree branches, but actually much farther in the distance, are the bright orbs of Saturn (left) and Mars. These planets formed along with the Earth and the early Solar System much earlier -- about 4.5 billion years ago. Swooping down...

    Explanation: Seen any planets lately? All three planets now shining brightly in the night sky are imaged in these panels, captured last week with the 1 meter telescope at Pic du Midi Observatory in the French Pyrenees. Near opposition and closest to Earth on May 30, Mars is presently offering the best ground-based photo-ops in the last decade. The sharp image finds clouds above the Red Planet's north pole (top) and towering volcanos near its right limb. Saturn reaches its own opposition tonight, its bright rings and gaps clearly revealed in the telescopic portrait. Jupiter is currently highest during the...

    Explanation: In this early May night skyscape, a mountain road near Bursa, Turkey seems to lead toward bright planets Mars and Saturn and the center of our Milky Way Galaxy, a direction nearly opposite the Sun in planet Earth's sky. The brightest celestial beacon on the scene, Mars, reaches its opposition tonight and Saturn in early June. Both will remain nearly opposite the Sun, up all night and close to Earth for the coming weeks, so the time is right for good telescopic viewing. Mars and Saturn form the tight celestial triangle with red giant star Antares just right of...

    All Good Things: Countdown Begins Toward Cassini's 'Grand Finale' Around Saturn By Leonidas Papadopoulos Artist's concept of Cassini's final orbits between the Saturn's innermost rings and the planet's cloud tops. This set of orbits will consist the last leg of Cassini's mission, called "The Grand Finale," which will culminate with a plunge on Saturn's atmosphere in September 2017. Image Credit: Image Credit: NASA/JPL It has become something of a hackneyed phrase, but in the case of NASA's Cassini spacecraft it is rather fitting: an epic mission of exploration of Saturn that has single-handedly changed our view of the ringed planet,...

    Contrary to recent reports, NASA’s Cassini spacecraft is not experiencing unexplained deviations in its orbit around Saturn, according to mission managers and orbit determination experts at NASA’s Jet Propulsion Laboratory in Pasadena, California. Several recent news stories have reported that a mysterious anomaly in Cassini’s orbit could potentially be explained by the gravitational tug of a theorized massive new planet in our solar system, lurking far beyond the orbit of Neptune.

    Explanation: Cassini, a robot spacecraft launched in 1997 by NASA, became close enough in 2002 to resolve many rings and moons of its destination planet: Saturn. At that time, Cassini snapped several images during an engineering test. Several of those images were combined into the contrast-enhanced color composite featured here. Saturn's rings and cloud-tops are visible toward the image bottom, while Titan, its largest moon, is visible as the speck toward the top. When arriving at Saturn in July 2004, the Cassini orbiter began to circle and study the Saturnian system. A highlight was when Cassini launched the Huygens probe...
