Europa, The Water Moon of Jupiter Poster
Downloadable poster of an ALMA observation of Europa. This intriguing image of Jupiter’s moon, Europa, was acquired with the Atacama Large Millimeter/submillimeter Array (ALMA), a state-of-the-art, radio-wavelength telescope array operated by an international partnership in the high elevation Chilean Andes. The highlighted region (white circle) is associated with a thermal anomaly and a potential water plume detected by both the Hubble Space Telescope and the unmanned Galileo spacecraft that studied Jupiter and its environment for eight years (1995-2003). The deep ocean that lies beneath Europa’s icy surface is perhaps the most promising place to search for present-day environments suitable for life.
