Are there active geysers at Enceladus’ north pole?
Water-vapor geysers erupt from cracks at the south pole of Saturn’s moon Enceladus. Scientists using Cassini data now have evidence for fresh ice at the moon’s north pole, too. Could it be more geysers for this fascinating ice moon? Source: https://earthsky.org/space/fresh-ice-enceladus-north-pole-geologic-activity…
