NASA plans to announce new findings Thursday based on its research into ocean worlds in our solar system. The small, icy world in orbit around Saturn is believed to have an ocean of water beneath its icy crust. Images from Cassini, the NASA spacecraft that's been in orbit around Saturn since 2004, have captured plumes of water vapour spewing into space.

In September, NASA spotted plumes of water vapour erupting from the surface.
