An ocean with no sky. Beneath Europa’s ice may lie a vast sea — but could that hidden world support life? This expanded Orbit Minute documentary follows the observations, the competing explanations and the engineering needed to investigate them. From Galileo’s four points of light to fractured ice, magnetic induction, tidal heating, water-rock chemistry, Webb carbon-dioxide maps and Europa Clipper, we separate what has been measured from what remains a hypothesis. No life on Europa is claimed to have been discovered. NASA and partner imagery, clearly labelled conceptual illustrations, and original teaching animations. English synthetic narration: Michael.
