Nothing like it has been seen before beyond our own planet: large tides have been found on Saturn's moon Titan that point to a liquid ocean - most likely water - swirling around below the surface.
On Earth, we are familiar with the combined gravitational effects of the Moon and Sun creating the twice-daily tidal rise and fall of our oceans. Less obvious are the tides of a few tens of centimetres in our planet's crust and underlying mantle, which floats on a liquid core.
But now the international Cassini mission to Saturn has found that Titan experiences large mbhtr ut mzg bnibmzp.
