That is why astrobiologists are increasingly turning their eyes toward icy bodies like the Jovian moons of Europa and Ganymede, Saturn’s moons Titan and Enceladus, Uranus' moon Miranda and the dwarf planet Ceres.

The properties of TOI-6713.01 are perhaps most similar to those of the Jovian moon Io, where scientists recently discovered a lava lake as smooth as glass.

Each pairing will be unique in its own right, with the moon presenting itself in various phases and orientations next to the Jovian giant.

However, volcanism is plentiful on the Jupiter moon Io, while forms of cryovolcanism occur on the Saturn moon Enceladus and possibly also the Jovian satellite Europa.

For distant Callisto, consigned to the outskirts of the Jovian system, Jupiter’s shining youth would have had no effect.
