AI Insight
Over 5,500 exoplanets have been discovered to date, with dozens located in their stars' habitable zones where liquid water could theoretically exist. Despite these discoveries, scientists have not yet definitively detected a liquid ocean on any exoplanet. NASA's planned next-generation observatory aims to achieve this capability by detecting ocean signatures on distant worlds.
Why it matters
Finding liquid oceans on exoplanets would be a major step in the search for potentially habitable environments beyond Earth. Such a discovery could help identify worlds where life as we know it might exist and guide future planetary exploration priorities.
Understand the Science
We’ve found more than 5,500 exoplanets so far. Dozens of them are in the habitable zones of their parent stars, where, at least in theory, they could host an ocean. But we’ve never definitively found a liquid ocean on another planet.
