    摘要: The Galileo spacecraft has detected diffuse optical emissions from to in high-resolution images acquired while the satellite was eclipsed by Jupiter. Three distinct components make up lo's visible emissions. Bright blue glows of more than 300 kilorayleighs emanate from volcanic plumes, probably due to electron impact on molecular sulfur dioxide. Weaker red emissions, possibly due to atomic oxygen, are seen along the Limbs, brighter on the pole closest to the plasma torus. A faint green glow appears concentrated on the night side of to, possibly produced by atomic sodium. to's disk-averaged emission diminishes with time after entering eclipse, whereas the localized blue glows brighten instead.
