    Europa, a 1931 anti-fascist film made by a Polish Jewish couple that was thought destroyed by the Nazis, has been restored and was shown this week for the first time in 80 years. The film, shot in Stefan and Franciszka Themerson’s bedroom in Warsaw, was based on Anatol Stern’s 1925 same titled poem, and was a statement about Europe’s increasing descent into violence and chaos. ..... The 12-minute film, making use of collages and photograms, is considered Poland’s first famous avant-garde film. n 1938, the couple fled to France where they left all five copies of their movie with Paris’s...

    This illustration of Jupiter's moon Europa shows how the icy surface may glow on its nightside, the side facing away from the Sun. Variations in the glow and the color of the glow itself could reveal information about the composition of ice on Europa's surface. Credit: NASA/JPL-Caltech ======================================================================= As the icy, ocean-filled moon Europa orbits Jupiter, it withstands a relentless pummeling of radiation. Jupiter zaps Europa's surface night and day with electrons and other particles, bathing it in high-energy radiation. But as these particles pound the moon's surface, they may also be doing something otherworldly: making Europa glow in the...

    Nasa is expected to make an announcement about 'surprising activity' on Jupiter's moon, Europa, on Monday. Many speculated that Nasa could finally be announcing evidence of life beyond Earth. The space agency, however, has poured cold water over these claims, tweeting that the much anticipated announcement will not be related to aliens.

    Explanation: What are those spots on Jupiter? Largest and furthest, just right of center, is the Great Red Spot -- a huge storm system that has been raging on Jupiter possibly since Giovanni Cassini's likely notation of it 355 years ago. It is not yet known why this Great Spot is red. The spot toward the lower left is one of Jupiter's largest moons: Europa. Images from Voyager in 1979 bolster the modern hypothesis that Europa has an underground ocean and is therefore a good place to look for extraterrestrial life. But what about the dark spot on the upper...

    If there is life in the Solar System outside of Earth, Jupiter's moon Europa and Saturn's moon Enceladus are two of the most likely spots to hold them. However, any extraterrestrial creatures on these celestial objects probably are not related to us, according to a new study. The research, presented at the annual fall meeting of the American Geophysical Union by Purdue University geophysicist Jay Melosh, looked at the idea of "lithopanspermia," an idea that life hopped from one planet to another via rocks that were ejected into space, according to Space.com, which first reported the news.

    NASA has a message for space lovers this month: Look up. The largest planet in the solar system, Jupiter, will be clearly visible June 10 — and to see its biggest moons you'll only need to grab a pair of binoculars. NASA said the gas giant is at its "biggest and brightest this month" and will be visible all night. The planet will reach opposition, the annual occurrence when the Jupiter, Earth and the Sun are arranged in a straight line, with Earth in the center. So, mark your calendars for Monday, as it will be the best time of...
  • The Purported Plumes of Jupiter's Moon Europa Are Missing 'Hotspot' Engines

    Space.com ^ | October 24, 2018 07:00am ET | Nola Taylor Redd,
    Plumes are common throughout the solar system. Jupiter's moon Io is constantly shooting volcanic material into the air. Saturn's icy moon Enceladus famously blasts water vapor and other material from its subsurface ocean into space via a set of geysers near the south pole. And Earth is rich in geysers, from Yellowstone National Park's Old Faithful to Iceland's Great Geysir. Firing off the gas that makes up these plumes requires an energy source, which usually heats up the ground around the plume source. Enceladus, Io and Earth all have hotspots around their geysers and volcanoes. But not Europa, as far...

    On Earth, the sublimation of massive ice deposits at equatorial latitudes under cold and dry conditions in the absence of any liquid melt leads to the formation of spiked and bladed textures eroded into the surface of the ice.Known as penitentes, these sublimation-sculpted blades grow to between 3 to 16 feet (1-5 m) tall, but they are restricted to high-altitude tropical and subtropical conditions, such as in the Andes.Europa, however, has the perfect conditions necessary for penitentes to form more uniformly — its surface is dominated by ice.It has the thermal conditions needed for ice to sublime without melting; and...
  • Jupiter's Moon Ganymede Generates Incredible Magnetic Waves

    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...
  • Jupiter's Icy Moon Europa Has a Really Weird Cold Spot

    Just because Jupiter's moon Europa is coated in ice doesn't mean all that ice is the same temperature. And now, scientists have mapped the hot and cold spots on the moon's surface using data gathered from Earth, with accuracy down to 125 miles (200 kilometers). While most of the temperature variations they measured can be explained by sunlight's influence on the ice, there's one unusually cold spot that is stumping the scientists behind the new research. That spot, which falls on the moon's northern hemisphere, stood out in images taken at different times of the day, which surprised the scientists....

    If signs of life exist on Jupiter's icy moon Europa, they might not be as hard to find as scientists had thought, a new study reports. The 1,900-mile-wide (3,100 kilometers) Europa harbors a huge ocean beneath its icy shell. What's more, astronomers think this water is in contact with the moon's rocky core, making a variety of complex and intriguing chemical reactions possible. Researchers therefore regard Europa as one of the solar system's best bets to harbor alien life. Europa is also a geologically active world, so samples of the buried ocean may routinely make it to the surface...
  • This May Be the Best Evidence Yet of a Water Plume on Jupiter's Moon Europa

    The case for a giant plume of water vapor wafting from Jupiter's potentially life-supporting moon Europa just got a lot stronger. NASA's Hubble Space Telescope has spotted tantalizing signs of such a plume multiple times over the past half decade, but those measurements were near the limits of the powerful instrument's sensitivity. Now, researchers report in a new study that NASA's Galileo Jupiter probe, which orbited the planet from 1995 to 2003, also detected a likely Europa plume, during a close flyby of the icy moon in 1997. The newly analyzed Galileo data provides "compelling independent evidence that there seems...

    Stay away from Europa? No way. It’s just too fascinating a place with its jigsaw-puzzle ice sheets, crisscross valleys, miles of ice on top and a warm, salty ocean below. The movie was prescient — if you’re going to search for life elsewhere in the solar system, Europa’s one of the best candidates. While we’ve sent spacecraft to photograph and study the icy moon during orbital flybys, no lander has yet to touch the surface. That may change soon. In early 2016, in response to a congressional directive, NASA’s Planetary Science Division began a pre-Phase A study to assess the...

    NASA's Juno Jupiter probe won't be settling into its final orbit around the giant planet this week after all. Juno was scheduled to fire its main engine for the final time during the probe's close Jupiter flyby on Wednesday (Oct. 19), in a maneuver that would reduce the time it takes the spacecraft to circle the gas giant from 53 Earth days down to 14 days. But the mission team decided to postpone the burn in order to investigate an issue with valves that are part of Juno's fuel-pressurization system, NASA officials said. "Telemetry indicates that two helium check valves...

    Astronomers using NASA's Hubble Space Telescope have imaged what may be water vapor plumes erupting off the surface of Jupiter's moon Europa. This finding bolsters other Hubble observations suggesting the icy moon erupts with high altitude water vapor plumes. The observation increases the possibility that missions to Europa may be able to sample Europa’s ocean without having to drill through miles of ice. “Europa’s ocean is considered to be one of the most promising places that could potentially harbor life in the solar system,” said Geoff Yoder, acting associate administrator for NASA’s Science Mission Directorate in Washington. “These plumes, if...

    Explanation: An enhanced-color view, this image covers a 350 by 750 kilometer swath across the surface of Jupiter's tantalizing moon Europa. The close-up combines high-resolution image data with lower resolution color data from observations made in 1998 by the Galileo spacecraft. Smooth ice plains, long fractures, and jumbled blocks of chaos terrain are thought to hide a deep ocean of salty liquid water beneath. Though the ice-covered alien ocean world is outside the Solar System's habitable zone, new studies show the potential chemistry driving its oxygen and hydrogen production, a key indicator of the energy available for life, could produce...
  • How Do We Terraform Jupiter’s Moons?

    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: Looking for an interplanetary vacation destination? Consider a visit to Europa, one of the Solar System's most tantalizing moons. Ice-covered Europa follows an elliptical path in its 85 hour orbit around our ruling gas giant Jupiter. Heat generated from strong tidal flexing by Jupiter's gravity keeps Europa's salty subsurface ocean liquid all year round. That also means even in the absence of sunlight Europa has energy that could support simple life forms. Unfortunately, it is currently not possible to make reservations at restaurants on Europa, where you might enjoy a dish of the local extreme shrimp. But you can...

    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...
