All kinds of excitement over potential life in space in the last week. Light years away – maybe, but beguilingly – on a planet that looks amazingly like earth. Squint and you can picture Earth-like oceans and land out there. And much closer to home, on a moon in the rings of Saturn. Icy and cold on the outside. But inside, evidence of an underground ocean in space. Sending geysers to the surface. Lighting up astro-biologists’ fondest dreams. Maybe teeming with life. This hour On Point: the buzz over life in space, maybe on an Earth-twin way out there, maybe on a moon close to home. And the push to learn more.
