Cassini Spacecraft Reveals 101 Geysers on Icy Saturn Moon
Scientists using mission data from NASA’s Cassini spacecraft have identified 101 distinct geysers erupting on Saturn’s icy moon Enceladus. Their analysis suggests it is possible for liquid water to reach from the moon’s underground sea all the way to its surface.
Over a period of almost seven years, Cassini’s cameras surveyed the south polar terrain of the small moon, a unique geological basin renowned for its four prominent “tiger stripe” fractures and the geysers of tiny icy particles and water vapor first sighted there nearly 10 years ago. The result of the survey is a map of 101 geysers, each erupting from one of the tiger stripe fractures, and the discovery that individual geysers are coincident with small hot spots. These relationships pointed the way to the geysers’ origin.
Thanks to recent analysis of Cassini gravity data, the researchers concluded the only plausible source of the material forming the geysers is the sea now known to exist beneath the ice shell. They also found that narrow pathways through the ice shell can remain open from the sea all the way to the surface, if filled with liquid water.
The fact that Enceladus’ sea is salty, laced with organic compounds, spouting into space, and maybe even rising up to the surface has raised this particular Saturnian moon as a major target for future exploration.

Australian photographer Ward Roberts has caught our eye, with his older series of work titled, Courts. In a beautiful collision of line, colour and symmetry, the series documents the simultaneously dense and empty expanses of sporting fields and courts around the world. Once populated and well-used, Courts makes a quiet comment on our indoors-y tendencies and abandonment of outdoor activities.
We’re drawn in by the bold pastels, colour codes and beautiful architectural structures which surround and complement the environments.
