    It’s Official: Saturn’s Rings Are Young January 3, 2018 | David F. Coppedge There’s no stretching the truth any more. Cassini data have led all the ringmasters to the conclusion that the rings of Saturn are not billions of years old. For over 15 years, Creation-Evolution Headlines has reported the tug-of-war between planetary scientists on the age of Saturn’s rings (e.g., 2/12/02). Indications that the rings are much younger than Saturn’s assumed age (4.5 billion years) go back to the Voyager missions. Several lines of evidence pointed to youth, but planetary scientists tugged back at the evidence, inventing ways to...

    Images from NASA's Cassini spacecraft show the closest-ever views of Saturn's swirled atmosphere and its massive hurricane. NASA/JPL-Caltech/Space Science Institute ================================================================================================================================ NASA's Cassini spacecraft is giving earthlings their closest-ever views of Saturn's swirled atmosphere and its massive hurricane, beaming a trove of images and data back to Earth after the craft made its first dive between Saturn and its rings Wednesday. Cassini is "showing us new wonders and demonstrating where our curiosity can take us if we dare," said Jim Green, director of NASA's Planetary Science Division. The raw images are being fed into a photo stream on NASA's website,...

And...Hillary will provide the final solution If ever there was proof that the establishment (aka “leftist”) members of the Republican Party are working with the Clinton Campaign, their faux horror over the Donald Trump male locker-room talk and huffy holier-than-thou departure from supporting him is the kicker…either that or they’ve not been around actual men much. They are the ones dividing and destroying the Republican Party. Not Trump. And, it most certainly seems that all of the GOP’ers (those who had already expressed their...

    An Arkansas woman who went to pick up the class ring she ordered from Walmart left disappointed, after store officials told her the retailer's new policy barred them from turning the item over -- because it bore an image of the Confederate flag. Elaine Glidewell told KFSM someone from the store in Fort Smith called her to pick up the ring she'd ordered for her nephew, but when she arrived on Tuesday, a clerk told her she couldn’t have it. The ring had been ordered before Walmart stopped selling items bearing images of the flag, in the wake of controversy...
  • Mystery object in Saturn's ring may be a new baby moon: Peggy

    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...

    Astronomers announced a contest today to name the two itty-bitty moons of Pluto discovered over the past two years. Three Pluto moons already have names associated with Hades and the underworld: Charon, the ferryman of Hades; the half-human, half-fish spirit Nix; and the multi-headed monster Hydra. The two unnamed moons need similarly shady references. Right now, they go by the bland titles of P4 and P5. They're no more than 15 to 20 miles across. Online voting will last two weeks. Twelve choices are available at plutorocks.com,
  • Hubble Telescope Spies Fifth Moon Around Pluto

    LOS ANGELES (AP) — There’s something lurking around distant and icy dwarf planet Pluto: a fifth moon. A team of scientists using the Hubble Space Telescope said Wednesday they have discovered the tiniest moon yet around Pluto. That brings the number of known moons to five. The mini-moon is estimated to be 6 to 15 miles across, smaller than the one that scientists spotted last year, which is 8 to 21 miles wide. Pluto’s largest moon, Charon, is about 650 miles across. Until the newly found moon gets a name, it will be known as P5.

    Explanation: Why does Jupiter have rings? Jupiter's rings were discovered in 1979 by the passing Voyager 1 spacecraft, but their origin was a mystery. Data from the Galileo spacecraft that orbited Jupiter from 1995 to 2003 later confirmed that these rings were created by meteoroid impacts on small nearby moons. As a small meteoroid strikes tiny Adrastea, for example, it will bore into the moon, vaporize, and explode dirt and dust off into a Jovian orbit. Pictured above is an eclipse of the Sun by Jupiter, as viewed from Galileo. Small dust particles high in Jupiter's atmosphere, as well as...

    Nature ^ | Tuesday, December 13, 2011 | Eric Hand
    NASA's Kepler space telescope... has identified 2,326 candidate planets, nearly doubling its haul since February. But what has puzzled observers and theorists so far is the high proportion of planets -- roughly one-third to one-half -- that are bigger than Earth but smaller than Neptune... Their very existence upsets conventional models of planetary formation and, furthermore, most of them are in tight orbits around their host star, precisely where the modellers say they shouldn't be. "It poses a challenge," says Douglas Lin, a planet-formation modeller and director of the Kavli Institute for Astronomy and Astrophysics at Peking University in Beijing,...

    Kepler has found the darkest known planet in universe--a Jupiter-sized exoplanet some 750 light-years away that is so black that it reflects just one percent of the light that reaches it. TrES-2b is so black that it’s darker than coal, or any other planet or moon that we’ve yet discovered. It’s less reflective than black acrylic paint. To summarize: it’s really, really black. But TrES-2b is not completely black. It emits an extremely faint red glow, like that of a hot ember. And it turns out that heat is the main culprit behind this darkest of dark planets. TrES-2b orbits...

    Dust from Pluto's satellites ought to form a faint ring around the dwarf planet, according to new calculations Until recently, the only ring in the Solar System was Saturn's. But in 1960s and 70s, astronomers discovered rings around Uranus and Neptune. Meanwhile, the Voyager 1spacecraft sent back images of Jupiter's ring. To be sure, these rings are much less impressive than Saturn's but the implications are clear: rings seem much more common than astronomers once thought. Perhaps they are even the norm. And that raises an interesting question: could Pluto possibly have a ring? The observational evidence is that Pluto...

    Astronomers using the Hubble Space Telescope have discovered a fourth moon orbiting the icy dwarf planet Pluto. The tiny, new satellite – temporarily designated P4 -- popped up in a Hubble survey searching for rings around the dwarf planet. The new moon is the smallest discovered around Pluto. It has an estimated diameter of 8 to 21 miles (13 to 34 km). By comparison, Charon, Pluto's largest moon, is 648 miles (1,043 km) across, and the other moons, Nix and Hydra, are in the range of 20 to 70 miles in diameter (32 to 113 km). "I find it remarkable...

    There is something around the moon of Rhea. It's not a ring, and it sure is weird, say researchers.Back in 2005, a suite of six instruments on the Cassini spacecraft detected what was thought to be an extensive debris disk around Saturn's moon Rhea, and while there was no visible evidence, researchers thought that perhaps there was a diffuse ring around the moon. This would have been the first ring ever found around a moon. New observations, however, have nixed the idea of a ring, but there's still something around Rhea that is causing a strange, symmetrical structure in the...

Richard Fisher, the director of NASA's Heliophysics Division, tells NPR's Guy Raz that this discovery is a big moment for the scientific community. "We thought we knew everything about everything, and it turned out that there were unknown unknowns."

    University of Arizona scientists have uncovered a curious case of missing asteroids. The main asteroid belt is a zone containing millions of rocky objects between the orbits of Mars and Jupiter. The scientists find that there ought to be more asteroids there than researchers observe. The missing asteroids may be evidence of an event that took place about 4 billion years ago, when the solar system's giant planets migrated to their present locations. UA planetary sciences graduate student David A. Minton and UA planetary sciences professor Renu Malhotra say missing asteroids is an important piece of evidence to support an...
