  • Jupiter's Moon Ganymede Generates Incredible Magnetic Waves

    08/07/2018 10:12:39 PM PDT · by BenLurkin · 26 replies
    Gizmodo ^ | 08/06/2018
    NASA’s Galileo spacecraft surprised scientists when it revealed that Jupiter’s moon Ganymede generated its own magnetic field. But new research shows Ganymede also creates incredibly powerful waves that rocket particles to enormous energies. Scientists revealed these huge electromagnetic waves while studying old data from Galileo, which orbited Jupiter from 1995 to 2003. The observations show another wild way that a moon can interact with the magnetic field of its planet. Jupiter’s radius is around 11 times that of Earth, but it is perhaps 20,000 times more magnetic. This generates an intense radiation environment around the planet. Typically, these waves around...

    Io boasts more than 130 active volcanoes with an estimated 400 total, making it the most volcanically active place in the Solar System. Juno used its Jovian Infrared Aurora Mapper (JIRAM) to take spectacular photographs of Io during Perijove 7 last July... Juno’s Io looks like it’s on fire. Because JIRAM sees in infrared, a form of light we sense as heat, it picked up the signatures of at least 60 hot spots on the little moon on both the sunlight side (right) and the shadowed half. Like all missions to the planets, Juno’s cameras take pictures in black and...

  • How Do We Terraform Jupiter’s Moons?

    04/22/2016 11:30:11 PM PDT · by BenLurkin · 39 replies
    Within the Jupiter system, there are 67 confirmed moons of varying size, shape and composition. In honor of Jupiter’s namesake, they are sometimes collectively referred to as the Jovians. Of these, the four largest – Io, Europa, Ganymede and Callisto – are known as the Galileans (in honor of their founder, Galileo Galilei). These four moons are among the largest in the Solar System, with Ganymede being the largest of them all, and even larger than the planet Mercury. In addition, three of these moons – Europa, Ganymede and Callisto – are all believed or known to have interior oceans...

    Explanation: Some of the Solar System's largest moons rose together on February 23. On that night, a twilight pairing of a waning gibbous Moon and Jupiter was captured in this sharp telescopic field of view. The composite of short and long exposures reveals the familiar face of our fair planet's own large natural satellite, along with a line up of the ruling gas giant's four Galilean moons. Left to right, the tiny pinpricks of light are Callisto, Io, Ganymede, [Jupiter], and Europa. Closer and brighter, our own natural satellite appears to loom large. But Callisto, Io, and Ganymede are actually...

    Explanation: On June 30, Venus and Jupiter were close in western skies at dusk. Near the culmination of this year's gorgeous conjunction, the two bright evening planets are captured in the same telescopic field of view in this image taken after sunset from Bejing, China. As the two bright planets set together in the west, a nearly Full Moon rose above the horizon to the south and east. Imaged that night with the same telescope and camera, the rising Moon from the opposite part of the sky is compared with the planetary conjunction for scale in the digitally composited image....

    A US radio telescope has captured images of an enormous lava lake on the surface of Io, one of the moons orbiting the planet Jupiter, the Puerto Rico Astronomy Society (PRAS) reported. "The new images clearly show an enormous lake of lava, fed from the subsoil and which exists permanently," PRAS vice president, professor and scientist Armando Caussade said in a statement. The Large Binocular Telescope Observatory in Arizona was the one that spotted the mass of lava in the region known as Loki Patera, a volcanic pit measuring approximately 200 kilometers (124 miles) in diameter. PRAS spokesman Juan Villafañe...

    The dwarf planet Pluto and its system of five moons are about as mysterious as the underworld of antiquity that inspired their names. ... “We are still baffled by how the system formed,” says study co-author Mark Showalter, a senior research scientist at the Search for Extraterrestrial Intelligence (SETI) Institute. “I think everyone believes that, at some point in the distant past, a large object bashed into ‘proto-Pluto’ and the moons formed out of the debris cloud. However, after that point in the story, details get very sketchy.” Now, analysis of data collected from the Hubble Space Telescope following the...

    Explanation: Our solar system's ruling giant planet Jupiter and 3 of its 4 large Galilean moons are captured in this single Hubble snapshot from January 24. Crossing in front of Jupiter's banded cloud tops Europa, Callisto, and Io are framed from lower left to upper right in a rare triple-moon conjunction. Distinguishable by colors alone icy Europa is almost white, Callisto's ancient cratered surface looks dark brown, and volcanic Io appears yellowish. The transiting moons and moon shadows can be identified by sliding your cursor over the image, or following this link. Remarkably, two small, inner Jovian moons, Amalthea and...
  • Griffith Observatory Extends Hours For Triple-Shadow Transit Of Jupiter’s Moons

    Angelenos will get their chance Friday to witness a rare celestial event when the shadows of three of Jupiter’s largest moons will fall upon Jupiter at the same time. Griffith Observatory will stay open one hour later than normal to allow visitors who are already at the park to watch the triple-shadow transit as Jupiter’s three moons – Io, Europa, and Callisto – will cross the planet’s disk throughout the evening. Three moon shadows will not appear simultaneously on Jupiter again, from Los Angeles, until 2032, according to the Observatory. As if the triple shadow transit weren’t enough, there will...

    Explanation: A 24 minute sequence from top to bottom, this intriguing series of telescopic frames tracks the occultation of Io by Callisto, two of Jupiter's Galilean moons, from San Pietro Polesine, Italy, planet Earth. A challenging observational project using a small telescope, the two contrasting Jovian worlds are both slightly larger than Earth's Moon. In fact, bright, volcanic Io and dark, cratered Callisto are about 3,640 and 4,820 kilometers in diameter respectively. With Earth itself now crossing near the orbital plane of Jupiter's moons, astronomers are enjoying a season of Galilean moon mutual events ranging from eclipses to occultations. The...

    Explanation: Two dark shadows loom across the banded and mottled cloud tops of Jupiter in this sharp telescopic view. In fact, captured on January 3rd, about a month after the ruling gas giant appeared at opposition in planet Earth's sky, the scene includes the shadow casters. Visible in remarkable detail at the left are the large Galilean moons Ganymede (top) and Io. With the two moon shadows still in transit, Jupiter's rapid rotation has almost carried its famous Great Red Spot (GRS) around the planet's limb from the right. The pale GRS was preceded by the smaller but similar hued...

    Iowa --(AmmoLand.com)- In the middle of America, you wouldn’t expect it to be so difficult to get a concealed carry permit. But in Iowa, it is — especially if the local sheriff doesn’t like you. That’s why I’m glad to introduce you to a great new organization fighting on this issue. Iowa Gun Owners has been pushing for a major reform of Iowa’s “Might Issue” concealed carry laws. Not since Alaska (in 2003) has a state passed a no-permit-needed concealed carry law, enacting real carry freedom for law-abiding gun owners. Iowa Gun Owners burst on to the scene in their...

    May 2, 2007—Jupiter's most turbulent moon, Io, is renowned among scientists for its flashy volcanic displays. But even experts were surprised when they saw this plume of gas vaulting nearly 200 miles (320 kilometers) over the moon's north pole. The giant frozen jet—about as tall as the state of New Hampshire is long—spewed from a volcano known as Tvashtar in February, just as NASA's New Horizons spacecraft was cruising by on its way to Pluto. The passing craft captured several images of the event, providing an unprecedented view of volcanism on Io, the most geologically active body in the solar...

    Kandahar Airfield, Afghanistan: Earlier this week, Glenn Reynolds reproduced an informal email from Afghanistan, which included an anecdote about the Canadian media maintaining the "Death Watch" (their own words) at Kandahar Airfield. The reporters are restricted to maintaining a presence at the airbase to report on potential deaths or wounding of Canadian soldiers. The soldiers resent the media for this, and the reporters do not like manning the DeathWatch as well. They are at the mercy of the news bureaus, who crave the sensational stories. Tonight I had the displeasure of witnessing the Death Watch in action. An Al Jazeera...

    A number of stories have been unreported on – or misreported – in the war of terror. The mainstream media is willing to discuss the car bombs. But which of these stories have been the most damaging in terms of not getting out? @ The memos from Saddam's regime. These memos, often ignored by major mass media outlets (unless targeted for derision), have generally shown the terrorist connections that Saddam's regime had, and showed that the regime was also interested in acquiring weapons of mass destruction. Far from lying, the Bush Administration had largely been spot on. @ Guantanamo Bay...
