    Explanation: What would it look like to fly over Titan? Radar images from NASA's robotic Cassini satellite in orbit around Saturn have been digitally compiled to simulate such a flight. Cassini has swooped past Saturn's cloudiest moon several times since it arrived at the ringed planet in 2004. The virtual flight featured here shows numerous lakes colored black and mountainous terrain colored tan. Surface regions without detailed vertical information appear more flat, while sufficiently mapped regions have their heights digitally stretched. Among the basins visualized is Kraken Mare, Titan's largest lake which spans over 1,000 kilometers long. Titan's lakes are...

    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...

    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.
  • Astronomy Picture of the Day -- Mimas: Small Moon with a Big Crater

    NASA ^ | October 21, 2014 | (see photo credit)
    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...

    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...
  • Saturn’s Moon Titan Has Salty Sea

    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...

    TITAN: rendering of methane lake, view of host planet saturn at night If you haven't been following, the NASA-ESA Cassini space mission has recently passed-by the largest of Saturn's 150 moons/moonlets: Titan is a natural satellite 1.5x the size of our own moon that makes up a full 90% of the orbiting mass around the gas giant.  And while Saturn is a large, windy gas ball, its planet-like moon Titan actually has a solid surface compromised of mostly rocks and water ice, retains an atmosphere (majority nitrogen, same as Earth- yet 2x the pressure), and features massive lakes of methane/ethane -one the size of Lake...

    by Gina Cassini | Top Right News Outrageous. Reckless. Senseless. That is what many military families are calling the continuing ban on concealed carry for servicemembers on U.S. military bases. Bases like Ft. Hood, where 3 brave members of our military were gunned down by an apparently mentally-compromised Spc. Ivan Lopez. And the outrage will only grow in light of a new shocking report that Lopez was able to remain free for 15 to 20 minutes -- more than enough time for him to kill 3 and wound 16 -- before finally being confronted by a military policewoman, whereupon he took...

The vote was 6-3.Along with twelve sponsors and co-sponsors, Arizona State Sen. Kelli Ward introduced the Second Amendment Preservation Act in the Grand Canyon State. SB1294 prohibits the state from enforcing “any federal act, law, order, rule or regulation that relates to a personal firearm, firearm accessory or ammunition within the limits of this state.” “We’ve sat back and allowed the federal government to trample the Constitution long enough,” Ward said. “We’re going...
  • NASA's Cassini Spacecraft Obtains Best Views of Saturn Hexagon

    NASA.gov ^ | 12/04/13
    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...

    Explanation: Take a picture of Saturn in the sky tonight. You could capture a view like this one. Recorded just last month looking toward the south, planet Earth and ruins of the ancient temple of Athena at Assos, Turkey are in the foreground. The Moon rises at the far left of the frame and Saturn is the bright "star" at the upper right, near Virgo's alpha star Spica (picture with labels). If you do take a picture of Saturn or wave at Saturn and take a picture, you can share it online and submit it to the Saturn Mosaic Project....

    Consider it the first interplanetary photobomb. On July 19th, NASA's Cassini spacecraft will photograph Earth through the rings of Saturn--and NASA wants you to jump into the shot. "Cassini has photographed Earth before, but this will be the first time Earthlings know in advance their picture will be taken from a billion miles away," says Linda Spilker, Cassini project scientist at NASA's Jet Propulsion Laboratory in Pasadena, CA. "We hope that people around the world will go outside to wave at Saturn while the photo-shoot is underway."

    Beneath the South Pole of Saturn Credit: Cassini Imaging Team, SSI, JPL, ESA, NASA Explanation: What clouds lurk beneath Saturn's unusual South Pole? To help find out, the robotic Cassini spacecraft currently orbiting Saturn imaged the nether region of the gigantic ringed orb in infrared light. There thick clouds appear dark as they mask much of the infrared light emitted from warmer regions below, while relatively thin clouds appear much lighter. Bands of clouds circle Saturn at several latitudes, while dark ovals indicate many dark swirling storm systems. Surprisingly, a haze of upper level clouds visible towards Saturn's equator disappears...

    Explanation: It was one of the largest and longest lived storms ever recorded in our Solar System. † First seen in late 2010, the above cloud formation in the northern hemisphere of Saturn started larger than the Earth and soon spread completely around the planet. The storm was tracked not only from Earth but from up close by the robotic Cassini spacecraft currently orbiting Saturn. Pictured above in false colored infrared in February, orange colors indicate clouds deep in the atmosphere, while light colors highlight clouds higher up. The rings of Saturn are seen nearly edge-on as the thin blue...

    Explanation: Orbiting in the plane of Saturn's rings, Saturnian moons have a perpetual ringside view of the gas giant planet. Of course, while passing near the ring plane the Cassini spacecraft also shares their stunning perspective. The thin rings themselves slice across the middle of this Cassini snapshot from April 2011. The scene looks toward the dark night side of Saturn, in the frame at the left, and the still sunlit side of the rings from just above the ringplane. Centered, over 1,500 kilometers across, Rhea is Saturn's second largest moon and is closest to the spacecraft, around 2.2 million...

    Like most New Yorkers, I have real estate fever. Even though I hate moving, I can't travel anywhere without wondering what it would be like to live there. I can't walk down a street in Oaxaca or the East Village without window shopping for apartments and evaluating the restaurant scene and the availability of playgrounds. It doesn't stop there. Roll a sleeping bag out under the sky in a place like Mesa Verde, 7,000 feet up in the Colorado Rockies, on a summer evening and you will wake up at midnight with your nose in the Milky Way.

    ....The evidence is mounting that not only do we have more than a century's worth of recoverable oil in the United States alone (even if there is a limit to the earth's oil supply), but that we also actually have a limitless supply of Texas tea because oil is in fact a renewable resource that is being constantly created deep under the earth's surface and which rises upward, where microscopic organisms that thrive in the intense pressure and heat miles below us interact with and alter it. In other words, we have an unending supply of oil, some of which...
