Ice shell thickness reveals water temperature on ocean worlds

Decades before any probe dips a toe—and thermometer—into the waters of distant ocean worlds, Cornell astrobiologists have devised a novel way to determine ocean temperatures based on the thickness of their ice shells, ...

Saturn's largest moon most likely uninhabitable

A study led by Western astrobiologist Catherine Neish shows the subsurface ocean of Titan—the largest moon of Saturn—is most likely a non-habitable environment, meaning any hope of finding life in the icy world is dead ...

Using eclipses to calculate the transparency of Saturn's rings

A Lancaster University Ph.D. student has measured the optical depth of Saturn's rings using a new method based on how much sunlight reached the Cassini spacecraft while it was in the shadow of the rings.
