Nergal (crater) : ウィキペディア英語版 | Nergal (crater)
Nergal crater is a crater on Jupiter's moon Ganymede. It has a distinctive ejecta blanket surrounding it that's darker nearer the craters and brighter further away. The inner region of the ejecta is characterized by a lobate appearance indicative of the flow of a liquid (or slushy) substance over the surface. The flow was probably icy surface material melted by the energy released during the impact that formed the crater.
