Life on Europa or not, that is the question.
Discovered by Galileo in 1610, Europa has no mountains or valleys, no rivers or surface oceans, no craters or rocks. Its surface is tiled with thick ice plates, jostling with each other, occasionally launching plumes of water from the vast ocean underneath.
The icy surface provides protection from radiation. Jupiter's gravity cause tidal flexing and heating beneath.
Avg surface temp: −160°C to -220°C 🥶

  Evidence for an Ocean | Why Europa – NASA's Europa Clipper
  Earth’s first mission to conduct detailed reconnaissance of Jupiter’s moon, Europa. NASA’s Europa Clipper will determine if this ocean world has environments suitable for life to exist.
