NASA's Mars Odyssey spacecraft has captured these six infrared views of the Martian moon Phobos. These large moons, named Io, Europa, Ganymede, and Callisto, are each distinctive worlds. The next full Moon will be early Sunday morning, July 5, 2020. Europa may be the most promising place in our solar system to find present-day environments suitable for some form of life beyond Earth. Slightly smaller than Earth's Moon, Europa’s water-ice surface is crisscrossed by long, linear fractures, cracks, ridges, and bands.

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. Europa's surface is mostly solid water ice. 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. Kristen Erickson Europa orbits Jupiter, the fifth planet from the Sun.

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. Jupiter's volcanically active moon Io casts its shadow on the planet in this dramatic image from NASA's Juno spacecraft.

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. This may help provide water for astronauts exploring the Moon during the Artemis program. Didymos B is getting an official name of its own: Dimorphos. 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. 10 Need-to-Know Facts About Europa 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. Popular Destination There also will be a partial penumbral eclipse of the Moon. 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. They were first seen by Galileo Galilei in December 1609 or January 1610, and recognized by him as satellites of Jupiter in March 1610. Europa has no moons of its own.

Io Europa has an extremely thin oxygen atmosphere — far too thin for humans to breathe. 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. They are roughly the same size as Earth's moon, some are a … The four largest moons, visible from Earth with binoculars on a clear night, known as the "Galilean moons", are Io, Europa, Ganymede, and Callisto. It is crisscrossed by fractures. 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. Europa may be the most promising place in our solar system to find present-day environments suitable for some form of life beyond Earth. October 2020: The Next Full Moon is the Harvest Moon. 8

Europa has no rings, but some moons in the solar system may have had rings in the past. The next full Moon will peak after midnight on Wednesday morning, Sept. 2, 2020, The Moon will appear full for about three days around this time, from Monday evening through Thursday morning. Infrared images from NASA's Juno spacecraft are providing the first glimpse of Ganymede's icy north pole. Psyche, the NASA mission to explore a metal-rock asteroid of the same name, recently passed a crucial milestone.

2 After all, having all the ingredients to make a pie is not the same as having a pie. Jupiter has 53 named moons and another 26 awaiting official names.Combined, scientists now think Jupiter has 79 moons.

This image from NASA’s Juno spacecraft captures several storms in Jupiter’s southern hemisphere. This page showcases our resources for those interested in learning more about ocean worlds.

Europa Rising. Planetary scientist Geronimo Villanueva created the sunset simulations while building a tool for a possible mission to Uranus. Slightly smaller than Earth's Moon, Europa’s water-ice surface is crisscrossed by long, linear fractures, cracks, ridges, and bands. Europa is slightly smaller than Earth’s Moon and barely one-quarter the diameter of Earth itself. 10 The planet Jupiter's four largest moons are called the Galilean satellites after Italian astronomer Galileo Galilei, who first observed them in 1610. 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. Researchers have designed an ambitious observing program that will conduct some of Webb's first scientific observations. Technicians recently finished applying more than 180 blocks of ablative material to the heat shield for the Orion spacecraft. Amanda Barnett New results from the Juno mission suggest Jupiter is home to what's called "shallow lightning.". Europa's subsurface ocean might contain more than twice as much water as Earth The Galilean moons /ɡælɪˈliːən/ are the four largest moons of Jupiter—Io, Europa, Ganymede, and Callisto. Europa's subsurface ocean might contain more than twice as much water as Earth. 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. 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 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. Jupiter has 79 known natural satellites. Europa orbits Jupiter, the fifth planet from the Sun.

NASA Official: All These Worlds The Hubble image includes a new storm brewing on Jupiter, and a cousin of the famous Great Red Spot region gearing up to change color. Europa is named for a woman who, in Greek mythology, was abducted by the god Zeus — Jupiter in Roman mythology. Science Writer: Bill Dunford. Io has a mass of 8.93×1022 kg and takes 1.77 Earth days t… Social Media Lead:

The Galilean moons are by far the largest and most massive objects to orbit Jupiter. The moon’s ice shell is probably 10 to 15 miles (15 to 25 kilometers) thick, beneath w… Bring Your Spacesuit Most of the moons of Jupiter are small, with about 60 of the satellites being less than 6.2 miles in diameter.

Europa's surface is mostly solid water ice. Nothing in its Orbit The Next Full Moon is the Strawberry Moon, Mead Moon, Honey Moon, Vat Purnima, Poson Poya, and the LRO Moon. 7

Dr. Lori Glaze Familiar Size 5 The next full Moon will be on Thursday afternoon, Oct. 1, 2020. The Moon will appear full from Wednesday morning through Saturday morning. Europa has been visited by several spacecraft and more missions are planned. NASA's next giant leap may be aided by tiny lunar robots that would help scout the lunar surface. 6 It includes activities that can be done at home as well as videos, animations, stories, and articles. Europa has an extremely thin oxygen atmosphere — far too thin for humans to breathe. Don't Forget a Towel

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. Like Earth, Europa is thought to also contain a rocky mantle and iron core. There are many interesting moons orbiting the planet, but the ones of most scientific interest are the first four moons discovered beyond Earth—the Galilean satellites. The other 75 known moons and the rings together make up just 0.003% of the total orbiting mass.

It is crisscrossed by fractures. 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: This site is maintained by the Planetary Science Communications team at, October 2020: The Next Full Moon is the Harvest Moon, Cyclones of Color at Jupiter's North Pole, Hubble Captures Crisp New Portrait of Jupiter's Storms, September 2020: The Next Full Moon is the Corn, Fruit, Barley, and Hungry Ghost Moon, 'Shallow Lightning' and 'Mushballs' Reveal Ammonia to Juno Scientists, NASA's Webb Telescope Will Study Jupiter, Its Rings, and Two Intriguing Moons, August 2020: The Next Full Moon is the Sturgeon Moon, Juno Takes First Images of Jovian Moon Ganymede's North Pole, NASA Announces Mini Payload Challenge Winners, Heat Shield Milestone for First Crewed Orion Mission, Building NASA's Psyche: Design Done, Now Full Speed Ahead on Hardware, July 2020: The Next Full Moon is the Buck Moon, NASA Plans More SLS Rocket Boosters to Launch Artemis Moon Missions, NASA's First Planetary Defense Mission Target Gets a New Name, NASA Scientist Simulates Sunsets on Other Worlds, Rocket Motors for First Artemis Moon Mission Arrive at Spaceport, The Next Full Moon is the Strawberry Moon, UPDATE: Astronomers recategorize asteroid-like comet detected by ATLAS telescope, Newly Reprocessed Images of Europa Show 'Chaos Terrain' in Crisp Detail, CubeSat to Shine a Laser Light on Moon's Darkest Craters.
