Extraterrestrial Life
New research indicates that salty, nutrient-rich ice on Europa could sink through the moon's icy shell to feed its hidden ocean, potentially supporting life. Geophysicists at Washington State University used computer simulations to show this process, inspired by Earth's crustal delamination. The findings address a key habitability challenge for the Jupiter moon.

A new study suggests that Jupiter's moon Europa, long considered a prime candidate for extraterrestrial life due to its vast subsurface ocean, may lack the geological activity necessary to support living organisms. Researchers found that weak tidal forces from Jupiter result in a calm and inactive seafloor. This challenges hopes for habitable conditions beneath the moon's icy crust.
New research suggests the closest technological civilization in the Milky Way could be about 33,000 light years from Earth. For such a society to coexist with humanity, it would need to have endured for at least 280,000 years. The findings, presented at a joint meeting in Helsinki, underscore the rarity of extraterrestrial intelligence.
