... Jupiter's icy moon Europa has a metallic core and layered internal structure similar to the Earth's , while the heavily cratered moon Callisto is a mixture of metallic rock and ice with no identifiable central core, according to new results from NASA's Galileo mission . In addition, recent plasma wave observations from Galileo show no evidence of a magnetic field or magnetosphere around Callisto, but do hint at the prospect of a tenuous atmosphere. ...

Каллисто (спутник Юпитера ) . ... Каллисто имеет примерно такой же диаметр, как Меркурий. ... Кроме кратеров, некоторые из которых окружены ступенчатыми уступами, и особых областей, представляющих собой расходящиеся концентрические окружности, на Каллисто не выявлено никаких крупных элементов ландшафта. ... Поверхность этого спутника покрыта очень темным материалом, из-под которого на месте кратеров видны круги и расходящиеся лучи белого цвета - предположительно, водяного льда. ...
