A team of astronomers using the W. M. Keck Observatory in Hawaii has discovered that aurorae at visible lengths appear on all four of Jupiter’s major moons, namely Io, Europa, Ganymede, and Callisto. The discovery was made using the High-Resolution Echelle Spectrometer (HIRES) at the Keck Observatory, as well as other high-resolution spectrographs at the Large Binocular Telescope and Apache Point Observatory.
Astronomers have long suspected that Europa, Jupiter's moon, holds a salty ocean beneath its thick icy crust that could support life. NASA has confirmed that they have now detected water erupting from geysers on the surface of the moon. An international research…
Astronomers have again imaged what may be water vapor plumes erupting off the surface of Jupiter's moon Europa, bolstering other observations suggesting the icy moon erupts with high altitude water plumes. The observation increases the possibility that missions…
Data from the Hubble space telescope suggests that enormous jets of water, more than 200 kilometers tall, may be spurting intermittently from the surface of Europa, ice-shelled moon of Jupiter.
Although it’s been known since 2005 that
