A surprising connection between the ice shell on Jupiter's moon and the Greenland ice sheet on Earth has provided new insight: Europa’s ocean may be habitable, according to a new study

On Jupiter's moon Europa, a saltwater ocean exists deep beneath a thick ice shell. Now, a surprising connection between the ice shell and the Greenland ice sheet on Earth has provided new insight: Europa's ocean may be habitable, according to a new study.
Scientists have been intrigued for more than 20 years by dramatic gashes on Europa's icy surface. These double ridges have crests that can reach almost 1,000 feet high, with wide valleys between them. These features were first imaged by the NASA Galileo spacecraft in the 1990s, but researchers haven't been able to determine how they formed.
