What"s the best mix of oceans to land for a habitable planet?
Earth is about 29% land and 71% oceans. How significant is that mix for habitability? What does it tell us about exoplanet habitability?.....»»
In a distant stellar system, the JWST sees the end of planet formation
Every time a star forms, it represents an explosion of possibilities. Not for the star itself; its fate is governed by its mass. The possibilities it signifies are in the planets that form around it. Will some be rocky? Will they be in the habitable.....»»
Life might be difficult to find on a single planet but may be obvious across many worlds
If we could detect a clear, unambiguous biosignature on just one of the thousands of exoplanets we know of, it would be a huge, game-changing moment for humanity. But it's extremely difficult. We simply aren't in a place where we can be certain that.....»»
