Europa

 A new study suggests Europa probably glows in the dark due to being bathed in radiation blasting out from Jupiter.

The color of the glow might allow astronomers to say something about the composition of Europa's surface.

The radiation environment on Europa is deadly. NASA limits radiation exposure for astronauts up to 50 Rem per year. The surface of Europa would expose astronauts to 540 Rem per day.
