NASA Official: Phillips Davis Jupiter's Moons This illustration shows the positions of Jupiter's four Galilean satellites — Io, Europa, Ganymede,and Callisto — in orbit about the planet for any date and time from January 1, 1900, to December 31 2100. 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. Europa's subsurface ocean might contain more than twice as much water as Earth. Discovered by Stephen Synnott through images taken by the Voyager 1 in 1979, Metis is the closest moon to Jupiter. Like Earth, Europa is thought to also contain a rocky mantle and iron core. Of these, 63 are less than 10 kilometres in diameter and have only been discovered since 1975.
It is crisscrossed by fractures. Infrared images from NASA's Juno spacecraft are providing the first glimpse of Ganymede's icy north pole. NASA's Lunar Flashlight, a briefcase-sized satellite, or CubeSat, will detect surface ice believed to be at the bottom of craters on the Moon that have never been exposed to sunlight. Slightly smaller than Earth's Moon, Europa’s water-ice surface is crisscrossed by long, linear fractures, cracks, ridges, and bands. Cyclones at the north pole of Jupiter appear as swirls of striking colors in this extreme false color rendering of an image from NASA’s Juno mission. Researchers have designed an ambitious observing program that will conduct some of Webb's first scientific observations. The Galilean moons /ɡælɪˈliːən/ are the four largest moons of Jupiter—Io, Europa, Ganymede, and Callisto.

This page showcases our resources for those interested in learning more about ocean worlds. Recently discovered object 2019 LD2, originally believed to be the first cometary “Jupiter Trojan” asteroid, turned out to be an interloper comet masquerading as a member of the Trojan population. Europa Rising. Site Manager: Abundant liquid water, energy and the right chemical elements make Europa one of the best places in the solar system to seek present day life beyond Earth. Europa's surface is mostly solid water ice.
The four are Io, Europa, Ganymede and Callisto.
This enhanced-color image from NASA’s Juno spacecraft captures the striking cloud bands of Jupiter’s southern latitudes. The next full Moon will be on Thursday afternoon, Oct. 1, 2020. The Latest Jupiter orbits the Sun at a distance of about 484 million miles (778 million kilometers). Io The four largest moons, visible from Earth with binoculars on a clear night, known as the "Galilean moons", are Io, Europa, Ganymede, and Callisto.
Europa has an extremely thin oxygen atmosphere — far too thin for humans to breathe. They are among the largest objects in the Solar System with the exception of the Sun and the eight planets, with radii larger than any of the dwarf planets. NASA has taken the next steps toward building Space Launch System (SLS) solid rocket boosters for as many as six additional flights.
The moon’s ice shell is probably 10 to 15 miles (15 to 25 kilometers) thick, beneath w… Amanda Barnett Abundant liquid water, energy and the right chemical elements make Europa one of the best places in the solar system to seek present day life beyond Earth. The next full Moon will be midday on Monday, August 3, 2020. Europa has been featured in short stories, comics and novels, with perhaps the best-known being the Arthur C. Clarke novel “2010: Odyssey Two,” which was also adapted for film. 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. These large moons, named Io, Europa, Ganymede, and Callisto, are each distinctive worlds. It is crisscrossed by fractures. Planetary scientist Geronimo Villanueva created the sunset simulations while building a tool for a possible mission to Uranus. They are roughly the same size as Earth's moon, some are a … But while Europa may turn out to have the necessary ingredients for life, it may still be lifeless. Didymos B is getting an official name of its own: Dimorphos. Europa is slightly smaller than Earth’s Moon and barely one-quarter the diameter of Earth itself. Icy Moon
Kristen Erickson Europa has no rings, but some moons in the solar system may have had rings in the past. Slightly smaller than Earth's Moon, Europa’s water-ice surface is crisscrossed by long, linear fractures, cracks, ridges, and bands. Scientists are using modern image processing techniques to create new views of Europa's surface. 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. After all, having all the ingredients to make a pie is not the same as having a pie.
The moon’s ice shell is probably 10 to 15 miles (15 to 25 kilometers) thick, beneath which the ocean is estimated to be 40 to 100 miles (60 to 150 kilometers) deep. 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. 4 1
Europa's surface is mostly solid water ice. 7
Europa's subsurface ocean might contain more than twice as much water as Earth Psyche, the NASA mission to explore a metal-rock asteroid of the same name, recently passed a crucial milestone. 2 Bill Dunford. 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: 5 There also will be a partial penumbral eclipse of the Moon. It has a diameter of 40 km (25 miles) and orbits Jupiter in 0.294780 Earth days, which is faster than Jupiter rotates on its axis. The next full Moon will be early Sunday morning, July 5, 2020. Europa has an extremely thin oxygen atmosphere — far too thin for humans to breathe. Jupiter's volcanically active moon Io casts its shadow on the planet in this dramatic image from NASA's Juno spacecraft. Don't Forget a Towel 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. Europa has no rings, but some moons in the solar system may have had rings in the past.
This image from NASA’s Juno spacecraft captures several storms in Jupiter’s southern hemisphere. With a diameter of 3,636 km (1,942 miles), Io is very close in size to our Moon and it is around 422,000 km (220,000 miles) from Jupiter. Technicians recently finished applying more than 180 blocks of ablative material to the heat shield for the Orion spacecraft. October 2020: The Next Full Moon is the Harvest Moon. Europa Exploration › Jupiter has 79 known natural satellites. 8 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.
Europa is named for a woman who, in Greek mythology, was abducted by the god Zeus — Jupiter in Roman mythology.
