    Ever since the Cassini space probe conducted its first flyby of Enceladus in 2005, the strange Saturnian moon has provided us with a treasure trove of images and scientific wonders. These include the jets of icy water vapor periodically bursting from its south pole, the possibility of an interior ocean – which may even harbor life – and the strange green-blue stripes located around the south pole. These stripes are essentially four fractures bounded on either side by ridges that appear to be composed of mint-green-colored ice. Known unofficially as “tiger stripes”, these surface fractures have become a source of...

    New images from NASA have captured the beautiful golden reflection of the sun on the polar sea of Saturn’s largest moon, Titan. It is the latest image from a collaborative four year mission studying the Saturnine system. The mirror-like reflection, known as the specular point, is in the south of Titan's largest sea, Kraken Mare – just north of an island archipelago separating two separate parts of the sea. To the human eye, this would appear as a haze but through Cassini’s Visual and Infrared Mapping Spectrometer (VIMS), “real color information” is provided in wavelengths that correspond to atmospheric...

    That’s what the Sun looks like reflecting off the seas of Titan, that moon of Saturn that excites astrobiologists because its chemistry resembles what early Earth could have looked like. This image represents the first time this “sunglint” and Titan’s northern polar seas have been captured in one mosaic, NASA said. What’s more, if you look closely at the sea surrounding the sunlight, you can see what scientists dub a “bathtub ring.” Besides looking pretty, this image from the Cassini spacecraft shows the huge sea (called Kraken Mare) was actually larger at some point in Titan’s past. “The southern portion...

    Explanation: When orbiting Saturn, be sure to watch for breathtaking superpositions of moons and rings. One such picturesque vista was visible recently to the robot Cassini spacecraft now orbiting Saturn. In 2006 April, Cassini captured Saturn's A and F rings stretching in front of cloud-shrouded Titan. Near the rings and appearing just above Titan was Epimetheus, a moon which orbits just outside the F ring. The dark space in the A ring is called the Encke Gap, although several thin knotted ringlets and even the small moon Pan orbit there.

    Explanation: Whatever hit Mimas nearly destroyed it. What remains is one of the largest impact craters on one of Saturn's smallest moons. The crater, named Herschel after the 1789 discoverer of Mimas, Sir William Herschel, spans about 130 kilometers and is pictured above. Mimas' low mass produces a surface gravity just strong enough to create a spherical body but weak enough to allow such relatively large surface features. Mimas is made of mostly water ice with a smattering of rock - so it is accurately described as a big dirty snowball. The above image was taken during the 2010 February...

The Sun's golden light is still scattered along the southwestern horizon though, captured after sunset on September 28. The evening gathering of wandering planets and Moon along with the bright star viewed as an equal to Mars and the Scorpion's Heart was enjoyed around planet Earth. But from the photographer's perspective looking across the calm waters of Lake Balaton, Hungary, they were joined by a more terrestrial sailboat mast light.

    NASA's Cassini spacecraft has discovered a "mysterious feature" on Saturn's moon Titan. Scientists are working to determine, what, exactly, this feature might be. NASA reports that the feature is roughly 100 square miles, and it lies in Ligeia Mare, one of Titan's hydrocarbon seas. Cassini's radar has observed the feature twice, but its appearance changed between the two sightings. Scientists suspect the feature's change in appearance could be the result of Titan's changing seasons, which Cassini's current extended mission will monitor. The feature's first sighting was in July 2013, and the radar images depicted a bright spot, which stood out...

    Explanation: How would Saturn look if its ring plane pointed right at the Sun? Before August 2009, nobody knew. Every 15 years, as seen from Earth, Saturn's rings point toward the Earth and appear to disappear. The disappearing rings are no longer a mystery -- Saturn's rings are known to be so thin and the Earth is so near the Sun that when the rings point toward the Sun, they also point nearly edge-on at the Earth. Fortunately, in this third millennium, humanity is advanced enough to have a spacecraft that can see the rings during equinox from the side....

    Explanation: Against dark rifts of interstellar dust, the ebb and flow of starlight along the Milky Way looks like waves breaking on a cosmic shore in this night skyscape. Taken with a digital camera from the dunes of Hatteras Island, North Carolina, planet Earth, the monochrome image is reminiscent of the time when sensitive black and white film was a popular choice for dimmly lit night- and astro-photography. Looking south, the bright stars of Sagittarius and Scorpius are near the center of the frame.

    Explanation: Acquiring its first sunlit views of far northern Saturn in late 2012, the Cassini spacecraft's wide-angle camera recorded this stunning, false-color image of the ringed planet's north pole. The composite of near-infrared image data results in red hues for low clouds and green for high ones, giving the Saturnian cloudscape a vivid appearance. Enormous by terrestrial standards, Saturn's north polar hurricane-like storm is deep, red, and about 2,000 kilometers wide. Clouds at its outer edge travel at over 500 kilometers per hour. Other atmospheric vortices also swirl inside the large, yellowish green, six-sided jet stream known as the hexagon....

    Explanation: Why does Enceladus have ice plumes? The discovery of jets spewing water vapor and ice was detected by the Saturn-orbiting Cassini spacecraft in 2005. The origin of the water feeding the jets, however, remained a topic of research. A leading hypothesis held that the source might originate from a deep underground sea, but another hypothesis indicated that it might just be ice melted off walls of deep rifts by the moon's tidal flexing and heating. Pictured above, the textured surface of Enceladus is visible in the foreground, while rows of plumes rise from ice fractures in the distance. These...

And some are, well, just weird. 10 MelchizedekProbably the single most mysterious figure in the Bible, Melchizedek was a priest-king of Salem (later known as Jerusalem) in the time of Abram (Abraham), suggesting a religious organization, complete with ritual and hierarchy, that predated the Jewish nation and their priestly lineage from the tribe of Levi.

    Explanation: What happened to half of Saturn? Nothing other than Earth's Moon getting in the way. As pictured above on the far right, Saturn is partly eclipsed by a dark edge of a Moon itself only partly illuminated by the Sun. This year the orbits of the Moon and Saturn have led to an unusually high number of alignments of the ringed giant behind Earth's largest satellite. Technically termed an occultation, the above image captured one such photogenic juxtaposition from Buenos Aires, Argentina that occurred early last week. Visible to the unaided eye but best viewed with binoculars, there are...

    According to new findings just published in this week’s edition of the journal Icarus, NASA’s Cassini Mission has brought to light new evidence of an actual ocean inside Titan, Saturn’s biggest moon. Furthermore, the ocean in question might even be as salt-laden as Earth’s Dead Sea. This is but the latest discovery resulting from an analysis of data on topography and gravity gathered during the past decade. Scientists discovered that an extremely high density was needed for the surface ocean of Titan to explain the information on the gravity. This means that Titan’s ocean has to be a very “salty...

    Explanation: Are Saturn's auroras like Earth's? To help answer this question, the Hubble Space Telescope and the Cassini spacecraft monitored Saturn's South Pole simultaneously as Cassini closed in on the gas giant in January 2004. Hubble snapped images in ultraviolet light, while Cassini recorded radio emissions and monitored the solar wind. Like on Earth, Saturn's auroras make total or partial rings around magnetic poles. Unlike on Earth, however, Saturn's auroras persist for days, as opposed to only minutes on Earth. Although surely created by charged particles entering the atmosphere, Saturn's auroras also appear to be more closely modulated by the...

New evidence confirms that, like Earth, Saturn's magnetic field helps create its own auroras. This space spectacle attracts a more fundamental question about where its magnetic field came from in the first place. Though Saturn is incredibly distant, the Hubble telescope was able to record its auroras in...

A combined team of researchers from Brown University in Rhode Island and the Lunar and Planetary Institute in Texas is suggesting in a paper they've uploaded to the preprint server arXiv, that an equatorial mountainous ridge on one of Saturn's moons has an exogenic origin. They are basing their theory on 3D models of the moon they've created and an analysis of the types of peaks present. Iapetus, the 3rd largest of Saturn's approximately 60 moons, is distinct for two reasons. One...

    L A Times ^ | April 15, 2014, 6:30 a.m. | By Karen Kaplan
    The moons that orbit Saturn may be increasing by one -- an icy, pint-sized object that astronomers have named “Peggy.” NASA’s Cassini spacecraft has spotted evidence that a mysterious object measuring perhaps half a mile across is disturbing the outer edge of Saturn’s large, bright A ring. The object’s gravity seems to have roughed up the ring’s usually smooth profile. As a result, a stretch of the A ring that measures 750 miles long and 6 miles wide is now about 20% brighter than it would typically appear. The fuzzy blob on the A ring’s edge was imaged by Cassini’s...

    Explanation: Why is Saturn partly blue? The above picture of Saturn approximates what a human would see if hovering close to the giant ringed world. The above picture was taken in 2006 March by the robot Cassini spacecraft now orbiting Saturn. Here Saturn's majestic rings appear directly only as a thin vertical line. The rings show their complex structure in the dark shadows they create on the image left. Saturn's fountain moon Enceladus, only about 500 kilometers across, is seen as the bump in the plane of the rings. The northern hemisphere of Saturn can appear partly blue for the...

    Scientists using data from NASA's Wide-field Infrared Survey Explorer, or WISE, have uncovered new clues in the ongoing mystery of the Jovian Trojans -- asteroids that orbit the sun on the same path as Jupiter. Like racehorses, the asteroids travel in packs, with one group leading the way in front of the gas giant, and a second group trailing behind. The observations are the first to get a detailed look at the Trojans' colors: both the leading and trailing packs are made up of predominantly dark, reddish rocks with a matte, non-reflecting surface. What's more, the data verify the previous...

    Explanation: Asteroids can have rings. In a surprising discovery announced two weeks ago, the distant asteroid 10199 Chariklo was found to have at least two orbiting rings. Chariklo's diameter of about 250 kilometers makes it the largest of the measured centaur asteroids, but now the smallest known object to have rings. The centaur-class minor planet orbits the Sun between Saturn and Uranus. The above video gives an artist's illustration of how the rings were discovered. As Chariklo passed in 2013 in front of a faint star, unexpected but symmetric dips in the brightness of the star revealed the rings. Planetary...

    Explanation: Do underground oceans vent through the tiger stripes on Saturn's moon Enceladus? Long features dubbed tiger stripes are known to be spewing ice from the moon's icy interior into space, creating a cloud of fine ice particles over the moon's South Pole and creating Saturn's mysterious E-ring. Evidence for this has come from the robot Cassini spacecraft now orbiting Saturn. Pictured above, a high resolution image of Enceladus is shown from a close flyby. The unusual surface features dubbed tiger stripes are visible in false-color blue. Why Enceladus is active remains a mystery, as the neighboring moon Mimas, approximately...

    The Saturn moon Enceladus harbors a big ocean of liquid water beneath its icy crust that may be capable of supporting life as we know it, a new study reports. The water ocean on Enceladus is about 6 miles (10 kilometers) deep and lies beneath a shell of ice 19 to 25 miles (30 to 40 km) thick, researchers said. Further, it's in direct contact with a rocky seafloor, theoretically making possible all kinds of complex chemical reactions — such as, perhaps, the kind that led to the rise of life on Earth. "The main implication is that there are...

    Scientists have made a stunning discovery in the outer realm of the solar system — an asteroid with its own set of rings that orbits the sun between Saturn and Uranus. The space rock is the first non-planetary object ever found to have its own ring system, researchers say. The pair of space rock rings encircle the asteroid Chariklo. They were most likely formed after a collision scattered debris around the asteroid, according to a new study unveiled today (March 27). The asteroid rings also suggests the presence of a still-undiscovered moon around Chariklo that's keeping them stable, researchers said....

    Scientists believe they have detected the first liquid waves on the surface of another world. The signature of isolated ripples was observed in a sea called Punga Mare on the surface of Saturn's moon Titan. However, these seas are filled not with water, but with hydrocarbons like methane and ethane. These exist in their liquid state on Titan, where the surface temperature averages about -180C. Planetary scientist Jason Barnes discussed details of his findings at the 45th Lunar and Planetary Science Conference (LPSC) in Texas this week.

    For scientists who spend time thinking about how planets form, life would be simpler if gas giants like Jupiter and Saturn didn’t exist. According to the standard model of planet formation, called "core accretion," planets form over millions of years as enormous blocks of rock and ice smash together to form planetary embryos, called "protoplanets," and eventually full-fledged planets. Most scientists agree that core accretion is how terrestrial planets such as Earth and Mars were created, but the model can’t convincingly explain how gas giant planets like Jupiter and Saturn came to be. One major problem is that developing gas...

    Explanation: If this is Saturn, where are the rings? When Saturn's "appendages" disappeared in 1612, Galileo did not understand why. Later that century, it became understood that Saturn's unusual protrusions were rings and that when the Earth crosses the ring plane, the edge-on rings will appear to disappear. This is because Saturn's rings are confined to a plane many times thinner, in proportion, than a razor blade. In modern times, the robot Cassini spacecraft orbiting Saturn now also crosses Saturn's ring plane. A series of plane crossing images from 2005 February was dug out of the vast online Cassini raw...

    You're looking at a newly released 8-frame movie of Saturn's enigmatic "hexagon." It is the highest-resolution footage ever acquired of the massive six-sided maelstrom atop the ringed planet's north pole, and boy howdy is it gorgeous. For the uninitiated, Saturn's uncannily symmetric cloud system measures roughly 20,000-miles across, and is utterly unique in our solar system. Its dimensions and dynamics are just bizarre. At the hexagon's center whirls a tightly wound hurricane roughly fifty-times larger than the average hurricane-eye on Earth. About it spins an assortment of smaller vortices, caught up in the hexagon's jet stream, that rotate clockwise, even...

    Janus and Epimetheus travel in nearly the same track, about 94,100 miles (151,500 km) out from Saturn. They occasionally pass each other, their gravity causing them to switch speeds and positions as they do; Janus goes faster and higher one time, slower and lower the next – but the two never come within more than about 6,200 miles of each other. The two moons switch positions roughly every four years. This scenario is referred to in astrophysics as a 1:1 resonance. Astronomers were initially confused when the moons were discovered in 1966 as it wasn’t known at the time that...

    It is frustrating, at a time when other nations are in ascendancy in space, that the administration of U.S. President Barack Obama seems committed to undermining the nation's own solar system exploration program. The Obama administration cut NASA's planetary-sciences budget by 20 percent in 2013. It has taken the National Research Council's (NRC) recommendations for prioritizing planetary investments in bad economic times and turned those recommendations upside down. The administration continues to favor large, directed projects at the expense of programs and missions that are openly competed.

    In an end-of-year interview on Al-Nahar TV, Egyptian astrologer Sayyed Al-Shimi warned that whenever Saturn enters a fire sign, the Jews become stronger. Attributing various events, including the first World Zionist Congress, the Balfour Declaration, and the 1948, 1956, and 1967 wars, to the constellation of the stars, Al-Shimi warned that in December 2014, Saturn would enter Sagittarius again.Following are excerpts from the interview, which aired on Al-Nahar TV and was posted on the Internet on December 31, 2013: Sayyed Al-Shimi: Saturn will enter the fire sign of Sagittarius. My late father and I have had a long history with...

    The extreme challenges and conditions faced by rovers during missions to explore other planets has inspired researchers and engineers to look into alternative, more suitable designs. After considering the complicated choreography of a regular landing – as we saw with the Mars Curiosity rover in August last year – as well as the challenging terrain a rover often faces once it reaches a planet’s surface, engineers at NASA have come up with an ultra-flexible squishable robot designed to effortlessly cope with any planetary surface it finds itself on. Although the so-called Super Ball Bot has been in development for...

    PARIS (AFP) - Uranus has puzzled scientists ever since the probe Voyager 2 did a flyby in 1986 and found that its magnetic field appeared to break the planetary rulebook. The evidence from Earth, Jupiter and Saturn determined that a planet's magnetic field should be like that of a bar magnet, with a north and south pole that runs roughly along the sphere's rotational axis. But Uranus -- and Neptune, too, Voyager found -- are radically different. Their magnetic fields are tipped over (the north-to-south line lies midway to the equator or even closer) and there are two north and...

    NASA's Cassini spacecraft has obtained the highest-resolution movie yet of a unique six-sided jet stream, known as the hexagon, around Saturn's north pole. This is the first hexagon movie of its kind, using color filters, and the first to show a complete view of the top of Saturn down to about 70 degrees latitude. Spanning about 20,000 miles (30,000 kilometers) across, the hexagon is a wavy jet stream of 200-mile-per-hour winds (about 322 kilometers per hour) with a massive, rotating storm at the center. There is no weather feature exactly, consistently like this anywhere else in the solar system. "The...
  • Bizarre Saturn Vortex Swirls in Stunning New NASA Video (aka The Hexagon)

    A NASA probe has captured an amazing video of the huge and mysterious six-sided vortex spinning around Saturn's north pole. Scientists created the new video of Saturn's vortex from 128 images snapped by NASA's Cassini spacecraft in December 2012. It's the highest-resolution movie yet obtained of the giant hexagon, which is about 20,000 miles (32,000 kilometers) wide and has been swirling for at least 30 years, researchers said. "The hexagon is just a current of air, and weather features out there that share similarities to this are notoriously turbulent and unstable," Andrew Ingersoll, a Cassini imaging team member at the...

    Explanation: In the shadow of Saturn, unexpected wonders appear. The robotic Cassini spacecraft now orbiting Saturn drifted in giant planet's shadow earlier this year and looked back toward the eclipsed Sun. Cassini saw a unique and celebrated view. First, the night side of Saturn is seen to be partly lit by light reflected from its own majestic ring system. Next, Saturn's expansive ring system appears as majestic as always even from this odd angle. Ring particles, many glowing only as irregular crescents, slightly scatter sunlight toward Cassini in this natural color image. Several moons and ring features are also discernible....

    Explanation: This image of Saturn could not have been taken from Earth. No Earth based picture could possibly view the night side of Saturn and the corresponding shadow cast across Saturn's rings. Since Earth is much closer to the Sun than Saturn, only the day side of the ringed planet is visible from the Earth. In fact, this image mosaic was taken earlier this month by the robotic Cassini spacecraft now orbiting Saturn. The beautiful rings of Saturn are seen in full expanse, while cloud details are visible including the polar hexagon surrounding the north pole, and an extended light-colored...

    The University of Arizona Lunar and Planetary Laboratory is launching its Fall 2009 Evening Lecture Series with talks on wandering solar system planets and searches for hazardous asteroids from Mount Lemmon... Planetary sciences professor Renu Malhotra will speak on "Migrating Planets" on Tuesday, Sept. 15. [whoops] Did the solar system always look the way it is now? New studies by Malhotra and others find that the outer planets -- Jupiter, Saturn, Uranus and Neptune -- were more tightly clustered in the early solar system, then moved away from each other. Malhotra's models show that as the solar system evolved, Jupiter...

    Explanation: This friendly photo collage is constructed from more than 1,400 images shared by denizens of planet Earth as part of the Cassini Mission's July 19th Wave at Saturn event. The base picture of Earth corresponds to the view from the Saturn-orbiting Cassini spacecraft on that date as its own cameras recorded images including planet Earth as a pale blue dot in the background. Of course, Saturn was 9.65 Astronomical Units away at the time, so it took light from all the waving Earth dwellers just over 80 minutes to travel there. Want to smile? Download and zoom in to...

    Explanation: This is not a solar eclipse. Pictured above is a busy vista of moons and rings taken at Saturn. The large circular object in the center of the image is Titan, the largest moon of Saturn and one of the most intriguing objects in the entire Solar System. The dark spot in the center is the main solid part of the moon. The bright surrounding ring is atmospheric haze above Titan, gas that is scattering sunlight to a camera operating onboard the robotic Cassini spacecraft. Cutting horizontally across the image are the rings of Saturn, seen nearly edge on....

    Explanation: In a cross-Solar System interplanetary first, our Earth was photographed during the same day from both Mercury and Saturn. Pictured on the left, Earth is the pale blue dot just below the rings of Saturn, as captured by the robotic Cassini spacecraft now orbiting the gas giant. Pictured on the right, the Earth-Moon system is seen against a dark background, as captured by the robotic MESSENGER spacecraft now orbiting Mercury. In the MESSENGER image, the Earth (left) and Moon (right) shine brightly with reflected sunlight. MESSENGER took the overexposed image last Friday as part of a search for small...

    Explanation: You are here. Everyone you've ever known is here. Every human who has ever lived -- is here. Pictured above is the Earth-Moon system as captured by the Cassini mission orbiting Saturn in the outer Solar System. Earth is the brighter of the two spots near the center, while the Moon is visible to its lower left. The unprocessed image shows several streaks that are not stars but rather cosmic rays that struck the digital camera while it was taking the image. The image was snapped by Cassini on Friday and released on Saturday. At nearly the same time,...
