Phillips Davis 8 This means Jupiter spins nearly upright so that the planet, as well as Europa and Jupiter’s other dozens of moons, do not have seasons as extreme as other planets do. The magnitude of this difference changes as Europa orbits, creating tides that stretch and relax the moon’s surface. The spacecraft will use multiple flybys of the moon to investigate the habitability of this ocean world. Director, NASA Planetary Science Division: function fullHeightWidthIframe(){ Europa (der Name stammt von einer phönizischen Prinzessin, in die sich Jupiter einst verliebte) ist etwas kleiner als Io und umrundet Jupiter einmal in 3,5 Tagen.. Der Mond setzt sich aus verschiedenen Schichten zusammen. Europa is slightly smaller than Earth’s Moon and barely one-quarter the diameter of Earth itself. Europa has no rings, but some moons in the solar system may have had rings in the past. Credit: NASA Visualization Technology Applications and Development (VTAD), A 3D model of Europa Clipper, a future mission to Jupiter's ocean moon. Hubble snapped the picture … Großartige Videos, die Sie nirgendwo sonst finden. 4 Jupiter takes nearly 12 Earth years to orbit the Sun, and it rotates once about every 10 hours. Now scientists have detected the water vapor for the first time above Europa’s surface. The Galilean moons follow the same principle, being less dense the farther they are from Jupiter. Zodiacal light is sunlight reflected toward Earth by dust orbiting the Sun. $('.gltf_viewer iframe').css({'height': "450px", 'width': '1px', 'max-width': '100%', 'min-width': '100%'}) Jupitermond Europa speit Wasserfontänen ins All. 05/05/2003 156 views 2 likes 220882 ID. All These Worlds Like. These “extremophile” life forms give scientists clues about how life may be able to survive beneath Europa’s ice shell. If it can be demonstrated that life formed independently in two places around the same star, it would then be reasonable to suspect that life springs up in the universe fairly easily once the necessary ingredients are present, and that life might be found throughout our galaxy, and the universe. In fact, the Galilean satellites are sometimes called a “mini solar system” since they formed from the leftovers of Jupiter similar to how Earth and other planets formed from gas and dust left over from the formation of our Sun. Europa’s water-ice surface is crisscrossed by long, linear fractures. Beziehungsweise einer der vielen Monde des Jupiters. Those four moons are likely about the same age as the rest of the solar system — about 4.5 billion years old. fullHeightWidthIframe() CAPE CANAVERAL, Fla. -- Jupiter and its enticing moon Europa shine in a new photo by the Hubble Space Telescope. Jupiter, the most massive planet in the solar system and the fifth in distance from the Sun. "@type": "3DModel", Verfasst von Denise. On of the most spectacular space endeavours of all time was the research of the Jupiter system: the NASA Galileo mission. Eine Gruppe von Wissenschaftlerinnen und Wissenschaftler, unter anderem aus dem Max-Planck-Institut für Sonnensystemforschung in Göttingen, haben jetzt neue Hinweise auf dieses Schauspiel gefunden. Der Jupiter-Mond Europa gilt als ein Kandidat, den die Nasa auf der Suche nach Leben ins Visier genommen hat. Europa has been visited by several spacecraft and more missions are planned. Amanda Barnett Decades ago, science fiction offered a hypothetical scenario: What if alien life were thriving in an ocean beneath the icy surface of Jupiter’s moon Europa? Kristen Erickson In 2011, scientists studying Galileo data proposed that chaos terrains could be places where the surface collapsed above lens-shaped lakes embedded within the ice. Europa is one of 79 known moons orbiting the gas giant, and is the sixth largest in the entire solar system. There are few impact craters on Europa—the number per unit area is comparable to that on the continental regions of Earth, indicating that the surface is relatively recent. Europa rotates once on its axis and completes one orbit of Jupiter every 3.5 Earth days, so the same side of Europa always faces Jupiter. Jupiter moon Europa. Europa has no rings, but some moons in the solar system may have had rings in the past. Set to launch next year, the agency’s Psyche spacecraft will explore a metal-rich asteroid in the main asteroid belt between Mars and Jupiter. Tips for photographing the sky during December's conjunction of Saturn and Jupiter. While evidence for an internal ocean is strong, its presence awaits confirmation by a future mission. Europa ist ein faszinierender Ort. Details Related. 7 Scientists believe that Europa is especially notable because it may have twice as much water as Earth, though it is so cold on Europa that water on the surface of this moon is frozen. While no plumes were observed while the Galileo spacecraft was in the Jupiter system in the 1990’s, more recent observations from telescopes such as Hubble Space Telescope, as well as a reanalysis of some data from the Galileo spacecraft, have suggested that it is possible that thin plumes of water are being ejected 100 miles (160 kilometers) above Europa’s surface. $('body').css('overflow','') 2 Europa rotates once on its axis and completes one orbit of Jupiter every 3.5 Earth days, so the same side of Europa always faces Jupiter.

A passing spacecraft might even be able to sample Europa’s ocean without landing on the moon’s surface because it is possible that Europa’s ocean may be leaking out into space. Europa is one of the few places in the solar system, aside from Earth, for which there is very strong evidence suggesting a liquid water ocean is present today and is in contact with rock.​ This is important because life as we know it requires three key basic "ingredients": liquid water, an energy source, and organic compounds to use as the building blocks for biological processes. Jupiter’s moons Io, Europa, and Ganymede are in what is called a resonance – every time Ganymede orbits Jupiter once, Europa orbits twice, and Io orbits four times. Europa is one of Jupiter’s moons. Scientists are almost certain that hidden beneath the icy surface of Europa is a salty-water ocean thought to contain twice as much water as Earth’s oceans combined. A Darker Realm if($full.length > 0){ setTimeout(function(){ With an equatorial diameter of 1,940 miles (3,100 kilometers), Europa is about 90 percent the size of Earth’s Moon. Jupiter’s large Galilean satellites (Io, Europa, Ganymede, and Callisto) likely formed out of leftover material after Jupiter condensed from the initial cloud of gas and dust surrounding the sun, early in the history of the solar system. $full.find('iframe').css({'height': h, 'width': w, 'min-width': '', 'max-width': ''}) The team measured the vapor using a spectrograph at the Keck Observatory in Hawaii that measures the chemical composition of planetary atmospheres through the infrared light they emit or absorb. Some of Juno's latest findings touch on "hot spots" in the planet's atmosphere. Eine Landemission könnte. Europa's surface is mostly solid water ice. Planned for launch in 2022 and arrival at Jupiter in 2029, it will spend at least three years making detailed observations of the giant gaseous planet Jupiter and three of its largest moons, Ganymede, Callisto and Europa. NASA's Galileo spacecraft explored the Jupiter system from 1995 to 2003 and made numerous flybys of Europa. Life as we know it seems to have three main requirements: liquid water, the appropriate chemical elements, and an energy source. Europa could have all three of these ingredients, and its ocean may have existed for the whole age of the solar system, long enough for life to begin and evolve there. Popular Destination A technique for scanning Mars rocks for microscopic fossils is also being developed to hunt for microbes on Enceladus, Titan, and Europa. Locked On Whether you're doing it for the nerd cred or the pie, this week on #10Things, we've got all the ways you can celebrate #PiDay with NASA. Sein Name stammt aus der griechischen Mythologie. One AU is the distance from Earth to the Sun. This view of Jupiter’s turbulent atmosphere from NASA’s Juno spacecraft includes several of the planet’s southern jet streams. 05/05/2003 178 views 2 likes 220882 ID. Europa is slightly smaller than Earth’s Moon and barely one-quarter the diameter of Earth itself. If Europa's ocean exists, the tidal heating could also lead to volcanic or hydrothermal activity on the seafloor, supplying nutrients that could make the ocean suitable for living things. Scientists think Europa’s ice shell is 10 to 15 miles (15 to 25 kilometers) thick, floating on an ocean 40 to 100 miles (60 to 150 kilometers) deep. Kristen Erickson They focus on our star, but three of NASA’s Sun-watching spacecraft have also captured unique views of the planets. A technique for scanning Mars rocks for microscopic fossils is also being developed to hunt for microbes on Enceladus, Titan, and Europa. } Because Europa's orbit is elliptical (slightly stretched out from circular), its distance from Jupiter varies, and the moon’s near side feels Jupiter’s gravity more strongly than its far side. Universum. Scientists could then study the material’s composition to determine whether Europa’s ocean might be hospitable for some form of life. As astronomers discovered asteroids hiding in Jupiter’s Lagrange points, they began referring to them as “Trojan asteroids.”. The Latest This view of Jupiter’s turbulent atmosphere from NASA’s Juno spacecraft includes several of the planet’s southern jet streams. Europa has a layer of ice and water on top of a rocky and metal interior, while Ganymede and Callisto actually have higher proportions of water ice and so lower densities. The spacecraft will become an explorer of the full Jovian system – Jupiter and its rings and moons. Europa, which is smaller than our own moon, appears as a pale dot alongside its giant, color-streaked gas planet. Und damit ist nicht der Kontinent gemeint (obwohl der auch ziemlich faszinierend ist), sondern der Mond des Jupiter. More recently Europa was the setting for the 2013 film “Europa Report,” and it was featured in an episode of the animated television show “Futurama.”, The moon has also been the setting or subject of several video games, including “Call of Duty: Infinite Warfare” and “Galaga: Destination Earth.”, Director, NASA Planetary Science Division: }) 6 Jupiter - Jupiter - Europa: The surface of Europa is totally different from that of Ganymede or Callisto, despite the fact that the infrared spectrum of this object indicates that it, too, is covered with ice. Europa (auch Jupiter II) ist der zweitinnerste Mond des Planeten Jupiter. So if we replaced our Moon with Europa, it would appear roughly the same size in the sky as our Moon does, but brighter — much, much brighter. Europa has no moons of its own. Bill Dunford, A 3D model of Jupiter's moon Europa, an icy moon with a hidden subsurface ocean. } In this NASA Cassini Spacecraft image released 21 December, 2000 the Galilean satellites Europa and Callisto are caught, under the watchful gaze of Jupiter, nearly perfectly aligned with each other, and the planet's center in this true color frame made of narrow angle images taken on 07 December 2000.EPA PHOTO NASA/NASA/CASSINI SPACECRAFT/NASA
