Large Lakes of Liquid Water Could Be Near the Surface of Europa

Jupiter’s moon Europa has a liquid water ocean under ice and that ice has many mysterious double ridge formations. A double ridge formation was found and analyzed in Northwest Greenland. The Greenland formation has the same gravity-scaled geometry as those found on Europa. Using surface elevation and radar sounding data, researchers show that this double…
Large Lakes of Liquid Water Could Be Near the Surface of Europa


Jupiter’s moon Europa has a liquid water ocean under ice and that ice has many mysterious double ridge formations. A double ridge formation was found and analyzed in Northwest Greenland. The Greenland formation has the same gravity-scaled geometry as those found on Europa. Using surface elevation and radar sounding data, researchers show that this double ridge was formed by successive refreezing, pressurization, and fracture of a shallow water sill within the ice sheet. If the same process is responsible for Europa’s double ridges, the results suggest that shallow liquid water is spatially and temporally ubiquitous across Europa’s ice shell.

This mechanism is based on the study of an analogous double ridge feature found on Earth’s Greenland Ice Sheet. Credit: Justice Blaine Wainwright

The Europa Clipper and the ESA’s JUICE mission (Jupiter Icy Moons Explorer) mission will be launching in 2024 and 2023 respectively. They could determine if there is near-surface water. Liquid water lakes near the surface would be far easier to search for life than an ocean under 30 kilometers of ice.

investigation on Europa Clipper could reveal whether or not this model for double ridge formation does indeed apply to Europa.

Canada a 22nd Century Superpower By Being a Great Place to Live

Canada has an 88-page immigration focused plan that would increase Canada’s population to the level of the USA in about 150 years. By 2171, Canada would use good schools, good universities and comfortable quality of life, solid economy to continue attracting high quality immigration to reach a population of about 300 million. This would be…

Ukraine Could Retake Kherson City Up to the Dnipro River

Ukraine will soon cutoff Russian troops in Kherson on the Northern side of the Dnipro River from resupply. They are destroying bridges and have already rendered certain bridges mostly unusable. This will enable Ukraine’s larger number of troops to outnumber and overwhelm Russian troops without resupply. This retaking of significant territory currently held by Russian…
