Abstract

Europa's Plumes Jupiter's moon Europa has a subsurface ocean and a relatively young icy surface. Roth et al. (p. 171 , published online 12 December 2013; see the Perspective by

Spencer

) analyzed spectral images taken by the Hubble Space Telescope that show ultraviolet emissions from the moon's atmosphere, and report a statistically significant emission signal extending above the satellite's southern hemisphere. This emission is consistent with two 200-km-high plumes of water vapor. Tidal stresses likely play a role in opening and closing fractures at the surface.
