geyser, holy water font, hydrothermal

NASA’s Cassini probe will today fly through icy geysers erupting on Saturn’s moon Enceladus, looking for signs that its ocean has hydrothermal vents like on Earth

holy water font :聖水池:通常置於教堂入口處,教友進聖堂時用右手中指蘸些聖水,在額頭上、胸前、左、右兩肩畫一大十字,同時口誦「因父,及子,及聖神之名,阿們。」表示對耶穌的尊敬,並提醒自己所領受的洗禮,也有淨化心靈之意。
