摘要: Abstract Pele has been the most intense high-temperature hotspot on Io to be continuously active during Galileo monitoring from 1996–2001. A suite of characteristics suggests that is an lava lake inside a volcanic depression. In 2000–2001, was observed by two spacecraft, Cassini and Galileo. The observations revealed variable in activity over timescales minutes, typical lakes Hawaii Ethiopia. These also short-wavelength thermal emission decreases with rotation factor significantly greater than cosine angle, color temperature becomes more hotter at high angles. This behavior significant portion visible comes fountains within topographically confined body. High spatial resolution, nightside images flyby October 2001 large, relatively cool (
