New research suggests that Jupiter's moon Europa may not have the conditions necessary to support life, despite having a vast hidden ocean. The findings indicate a lack of tectonic activity, which is thought to be a key factor in supporting life, and also cast doubt on the idea that Europa vents water into space. The study's results imply that Europa's ocean may be quiet and lifeless, contradicting previous suspicions, although a separate and unrelated study mentions saturn's moon titan, the focus remains on europa.
