Jupiter is a powerful source of radio waves in the night sky.
When space agencies send spacecraft to the giant planet they have to make sure that their orbits are calculated carefully so that they don’t spend too long inside the radiation belts of Jupiter. The zone’s high-energy particles are just too much.
So what happens if you’re a moon in orbit of Jupiter having to constantly withstand a relentless pummeling of high-energy radiation?
You glow in the dark, that’s what.
New research from scientists at NASA’s Jet Propulsion Laboratory suggest that Europa—the fourth largest of Jupiter’s 79 moons—may glow shades of green, blue and white even on its nightside.
The glow could reveal much about the composition of ice on Europa’s surface, say scientists—and the glow could be observed
