In recent decades, volcanic and cryovolcanic activity on moons within the Solar System has been recognised as an important source of cosmic dust. Two moons, Jupiter’s satellite Io and Saturn’s satellite Enceladus, are known to be actively emitting dust into circumplanetary and interplanetary space. A third moon, Europa, shows tantalising hints of activity. Here we review current observations and theories concerning the generation, emission and evolution of cosmic dust arising from these objects.

活动卫星的尘埃排放

近几十年来，太阳系卫星上的火山和冰火山活动被认为是宇宙尘埃的重要来源。已知两颗卫星，木星的卫星艾奥和土星的卫星土卫二，正在积极地向行星和行星际空间排放尘埃。第三颗卫星欧罗巴显示出诱人的活动迹象。在这里，我们回顾了当前关于这些天体产生的宇宙尘埃的产生、发射和演化的观察和理论。
