Astronomers were left stunned after observing a water vapour plume measuring 6,000 miles blasting from a Saturn moon. Known as Enceladus, the tiny moon is just 500 kilometres wide but was found to have a huge amount of active geysers in 2005 by the Cassini probe. This new discovery was made by a NASA spacecraft called the Hubble Space Telescope and is said to be an unexpected finding. The discovery was made thanks to the Telescopes’ sensitivity to ultraviolet light which was able to pick up the plume and analyse its chemical composition. It is believed that this plume could provide interesting information about the moon’s interior by sampling its subsurface ocean. Enceladus has been of particular interest to scientist as it is being considered to be one of the top targets for future exploration and the study of how life may exist in our solar system. The finding will likely spur on additional research into Enceladus, providing new insights into the mysteries of our universe.
