Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere.It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and Asia to the east. Europe shares the landmass of Eurasia with Asia, and of Afro-Eurasia with both Africa and Asia. [10] [11] Europe is commonly considered to be separated ...
Learn how Europa, one of Jupiter's moons, may have liquid water and the ingredients for life beneath its icy surface. Explore the history and future of exploring Europa and other ocean worlds in the solar system.
Europa, the smallest and second nearest of the four large moons (Galilean satellites) discovered around Jupiter by the Italian astronomer Galileo in 1610. It was probably also discovered independently that same year by the German astronomer Simon Marius, who named it after Europa of Greek mythology.Europa is a rocky object covered with an extremely smooth, elaborately patterned surface of ice.
Scientists describe Europa as an "ocean world" because decades of evidence from analysis of spacecraft observations strongly suggest that an ocean of liquid water is hidden beneath the moon's surface of ice. In fact, some of Europa's characteristics would be extremely difficult to explain if the moon does not contain a global subsurface ocean.
Exploring this ocean world with our Europa Clipper spacecraft could provide new clues in our search for life beyond Earth. Scheduled to launch in October 2024, Europa Clipper's main science goal is to determine whether there are places below the icy moon's surface that could be habitable.

The surface of Jupiter's moon Europa features a widely varied landscape, including ridges, bands, small rounded domes and disrupted spaces that geologists call "chaos terrain." Three newly reprocessed images, taken by NASA's Galileo spacecraft in the late 1990s, reveal details in diverse surface features on Europa.
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 lower densities. Structure. Structure. Like our planet, Europa is thought to have an iron core, a rocky mantle, and an ocean of salty water. Unlike Earth, however, Europa's ocean lies below a ...
Europa is tidally locked, so the same side faces Jupiter at all times. Size: Europa is 1,900 miles (3,100 km) in diameter, making it smaller than Earth's moon, but larger than Pluto. It is the ...
