NASA uncovers alluring 'chaos terrain' in its quest to find ocean on Jupiter's moon Europa

idea of life on Jupiter's ice-covered moon Europa has fascinated scientists for decades but it was in 1990s, with sharp ims from NASA's Galileo craft, that researchers came a step closer to believe in its possibility. NASA has w remastered some of Galileo's stunning ims of Europa, using improved new calibrations to introduce colours, in a bid to have a closer look at Jovian satellite. 

In splendid ims shared on Instagram, Europa's long erratic winding lines throw new light on its varied landscape. As explained by NASA, im shows a region where ice blocks have moved sideways, rotated or tilted before refreezing in ir new locations and to understand how it might have happened, scientists study se ice blocks like y were jumbled pieces of a puzzle.⁣⁣ While geologists have dubbed se as 'chaos terrain', remastered ims are simply fascinating.

Ocean on Europa

long curving lines in remastered ims hint at subsurface liquid water. While releasing se ims on NASA website, scientists elucidated that tidal motion experienced by Europa in its elliptical orbit around Jupiter supplies energy to keep ocean in a liquid state under an ice shell of 15 to 25 kilometres. cosmic ocean is estimated to be 60 to 150 kilometres deep. refore, while Jovian satellite is only one-fourth diameter of Earth, Europa's ocean is estimated to contain twice as much water as our planet. 

Most recent observations from Hubble telescope, and reanalysis of old Galileo data, have suggested that Europa's ocean may be leaking into . In fact, in vember 2019, an international team of scientist anunced detecting water vapours for first time above Europe's surface. observation was made using a spectrograph at NASA's Hawaii observatory as it measured chemical composition of Europa's atmosphere comparing infrared light emission and absorption.
