2019年1月8日 · This image reveals a cutaway view of the possible internal structure of Europa. The surface of Europa is an image obtained by NASA’s Galileo spacecraft in 1996, whereas the interior characteristics of the moon are inferred from …

2024年9月9日 · This artist's concept (not to scale) depicts what Europa's internal structure could look like: an outer shell of ice, perhaps with plumes of material venting from beneath the surface; a deep, global layer of liquid water; and a rocky interior, potentially with hydrothermal vents on …

1997年12月18日 · Cutaway view of the possible internal structure of Europa. The surface of the satellite is a mosaic of images obtained in 1979 by NASA's Voyager spacecraft.

This graphic shows the hypothesized internal structure of Jupiter’s moon Europa. Much is unknown about the moon’s subsurface, but research from a team at…

2019年1月7日 · The mosaic shows the surface of Europa to be structurally complex. The sun illuminates the scene from the right, revealing complex overlapping ridges and fractures in the upper and lower portions of the mosaic, and rugged, more chaotic terrain in the center.

An artist's impression of Europa's structure, including its surface, icy shell, and subsurface ocean.

4 天之前 · The interior structure of Europa records key information about its accretional environment and evolution and the potential for a habitable ocean 1,2,3.Geophysical constraints have been ...

1998年9月25日 · Europa is most likely differentiated into a metallic core surrounded by a rock mantle and a water ice-liquid outer shell, but the data cannot eliminate the possibility of a uniform mixture of dense silicate and metal beneath the water ice-liquid shell.

The shape of Europa provides insight into the structure and thickness of its ice shell (e.g., Nimmo et al. 2007) and the distribution of tidal heating (e.g., Ojakangas and Stevenson 1989). Europa Clipper will determine Europa’s shape through a combination of REASON altimetry profiles, EIS limb profiles, and Europa-UVS occultation measurements ...

2005年10月1日 · We consider models of Europa's internal structure with five to six layers including an outer water–ice layer, a silicate crust, a three-layer silicate mantle, and a Fe FeS core. By analogy with moon-size bodies, the crustal thickness and density are taken to be 60 km and 2700 kg m −3 .
