Hubble Finds More Evidence of Plumes on Europa

Hubble hasn’t found aliens on Europa, but it may have found new evidence that plumes of salt water from the moon’s globe-spanning salty ocean can escape through cracks in its icy shell.

Using its Space Telescope Imaging Spectrograph (STIS) instrument, Hubble captured far-ultraviolet images of what could be geysers of water from beneath the surface, erupting in Europa’s southern hemisphere. If the features in those images are really geysers, that could be very good news for future missions
