Some of Saturn’s moon have ice before their surface. For example, “Mimas appears to have a vast
global ocean underneath its icy shell, according to close measurements of its
orbit. If other icy worlds have similar oceans”.
For certain
evolutionists, this would mean life hospitable to life on the moon.
“Mimas is the smallest of Saturn’s seven major moons. It was long thought to be mostly composed of solid ice
and rock, but in 2014 astronomers observed that its orbit around Saturn was
unexpectedly wobbling, which could only be explained by either a rugby
ball-shaped core or a liquid ocean.
Many astronomers
rejected the ocean explanation because the friction needed to melt the ice
should also have produced visible marks on Mimas’s surface. However, recent
simulations have suggested that this ocean could exist without such
marks.
To look for more
clues, Valéry Lainey at the Paris Observatory in France and his colleagues
analysed observations of Mimas’s orbit made by NASA’s Cassini spacecraft. They
found that its orbit around Saturn has drifted around 10 kilometres over 13
years.
According to the
team’s calculations, this orbital drift could only have been produced by
wobbles from an icy shel sliding over an ocean, or a core with a physically
impossible pancake shape.”
