The glow could help scientists determine if a subsurface ocean on Europa is a good place to look for life.
Intense radiation from the giant planet Jupiter causes the night side of its moon Europa to visibly glow in the dark – a phenomenon that could help scientists learn if it can sustain simple forms of life, according to a new study.
The findings, published Monday in the journal Nature Astronomy, were the result of experiments by NASA scientists to study how Jupiter’s radiation affects the chemistry of Europa, which is thought to harbor a subsurface ocean of water.
And though telescopes haven’t yet observed the glow, the possibility that Europa glows in the dark could be verified by two probes that will study the moon in the coming years.
