What mysteries might be solved by peering into this crystal ball? This crystal ball is quite unusual because it is actually a moon ofJupiter, the crystals are ice-crystals, and the ball is not only dirty and opaque but cracked beyond repair. Nevertheless, speculation is rampant that oceans exist under these tortured ice-plains that could support life. Europa, the smallest of Jupiter's Galilean moons, was photographed last month in natural color by the robot spacecraft Galileo, now in orbit around Jupiter. The brown patches are what one might think: dirt -- tainting an otherwise white ice-crust. Europa, nearly the same size as Earth's Moon, similarly keeps one face toward its home planet. The hemisphere of Europa shown above is the one that always trails. Why is Europa's surface the smoothest in the Solar System? Where are Europa's craters?

Hubble Just Confirmed The Largest Ocean World in Our Solar System And Its Not On Earth: The Ganymede ocean is believed to contain more water than Europa's,” says Olivier Witasse, a project scientist working on ESA’s future Jupiter Icy Moon Explorer (JUICE). “Six times more water in Ganymede’s ocean than in Earth's ocean, and three times more than Europa. In March of 2016, NASA's Hubble Space Telescope revealed the best evidence yet for an underground saltwater ocean on Ganymede, Jupiter's largest moon larger than Mercury and not much smaller than Mars. Identifying liquid water is crucial in the search for habitable worlds beyond Earth and for the search for life, as we know it.This discovery marks a significant milestone, highlighting what only Hubble can accomplish.in its 25 years in orbit, Hubble has made many scientific discoveries in our own solar system. A deep ocean under the icy crust of Ganymede opens up further exciting possibilities for life beyond Earth. Ganymede is the largest moon in our solar system and the only moon with its own magnetic field. The magnetic field causes aurorae, which are ribbons of glowing, hot electrified gas, in regions circling the north and south poles of the moon. Because Ganymede is close to Jupiter, it is also embedded in Jupiter's magnetic field. When Jupiter's magnetic field changes,the aurorae on Ganymede also change, "rocking" back and forth. Just as Saturn's moon, Dione is perennially overshadowed by Enceladus and Titan, Ganymede's fame is eclipsed by its sister ocean world, Europa, slated for flybys by NASA’s Europa Clipper mission in the 2020s. Ganymede's cycles of auroral activity on the surface, detected by the Hubble Space Telescope, reveal oscillations in the moon’s magnetic field best explained by the internal heat-generating tidal sloshing of a huge ocean hundreds of kilometers below the surface. JUICE will fly by the moons at distances between 1000 and 200 kilometers, orbiting Ganymede for nine months, with the latter four months at an altitude of about 500 km. #Space #NASA #Moon #Ganymede #Jupiter #Europa #JUICE #Astronomy

.
Although the phase of this moon might appear familiar, the moon itself might not. In fact, this gibbous phase shows part of Jupiter's moon Europa. The robot spacecraft Galileo captured this image mosaic during its mission orbiting Jupiter from 1995 - 2003. Visible are plains of bright ice, cracks that run to the horizon, and dark patches that likely contain both ice and dirt. Raised terrain is particularly apparent near the terminator, where it casts shadows. Europa is nearly the same size as Earth's Moon, but much smoother, showing few highlands or large impact craters. Evidence and images from the Galileo spacecraft, indicated that liquid oceans might exist below the icy surface. To test speculation that these seas hold life, ESA has started preliminary development of the Jupiter Icy Moons Explorer (JUICE), a spacecraft proposed for launch around 2022 that would further explore Jupiter and in particular Europa. Recent observations by the Hubble Space Telescope have uncovered new evidence that Europa, like Saturn's moon Enceladus, has ice venting from its surface.

PLUMES ON EUROPA? Evidence was mounting for plumes like we've observed on Saturn's moon Enceladus, but this week scientists announced that mysterious data the magnetic fields (illustrated above) from Galileo's flyby of Jupiter's moon Europa may have been caused by plumes the spacecraft flew through! It's another reason to be excited for missions headed there in a few years - they may be able to directly observe and sample plumes - aka get key information about the interior habitability of Europa

I have always put all my bets on it!

With a diameter of almost 2,000 miles, an orbit equivalent to 3.5 Earth days and a mass about 65 percent of Earth's Moon, Europa is considered by some scientists a likely place to look for present-day environments suitable for life.

The latest analysis Europa make this Jovian moon one of the most promising places in the solar system to search for life. Europa has long been a high priority for exploration because beneath its icy crust lies a salty, liquid water ocean. NASA’s Europa Clipper, targeted to launch in 2022, will be equipped with the instruments necessary to determine whether Europa possesses the ingredients necessary to support life as we know it.

Another mission, Esa’s Jupiter Icy Moons Explorer, or Juice, is expected to launch around the same time and perform flybys of Europa and two other Jovian moons, Ganymede and Callisto.

Scientists found independent evidence that Europa’s subsurface liquid water reservoir may be venting plumes of water vapor above its icy shell when our Galileo mission collected data on the moon in 1997.

New analysis of old data brings new insights to the question of whether Jupiter’s icy moon Europa has the ingredients to support life. Scientists found independent evidence that Europa’s subsurface liquid water reservoir may be venting plumes of water vapor above its icy shell when our Galileo mission collected data on the moon in 1997.

Taken by our Galileo spacecraft in the late 1990s, this image shows the puzzling, fascinating surface of Europa. Long, linear cracks and ridges crisscross the surface, interrupted by regions of disrupted terrain where the surface ice crust has been broken up and re-frozen into new patterns.

Areas that appear blue or white contain relatively pure water ice, while reddish and brownish areas include non-ice components in higher concentrations. The polarregions, visible at the left and right of this view, are noticeably bluer than the more equatorial latitudes, which look more white. This color variation is thought to be due to differences in ice grain size in the two locations.

During our Europa Clipper mission, which may launch as early as June 2022, we will learn more about whether Europa has those necessary ingredients that could support life.

In the distance, a half moon and then the elliptical line of Mars, Saturn, Jupiter, Venus—all visible not too high in the sky as everything turned from orange cream to soft blue to gray slate.
.
Planet spotting and star gazing reminds me of how vast things are, and how small we are in comparison to all our bloated worries and fears.
.
Lucky for us and the kids, the observatory was open last night. Peering through the telescopes, we saw the rings of Saturn, then Jupiter and her four moons—Io, Callisto, Europa, Ganymede. Everything tiny and majestic, small enough to make me imagine what it would be like to reach out, pluck them from the darkness, and hold them in the palm of my hand like a lady bug. Then, at the same time, large enough to make me think that it’s impossible to comprehend the complexities of such wonders with the human mind.
