AstronomyNeptune-like worlds could become habitable
Mini-Neptunes can drift toward their stars and lose their atmospheres, leaving behind ice-rich rocky cores that can become watery worlds.
-
AstronomyOldest solar system unearthed by Kepler
Five rocky planets orbit the 11.2-billion-year-old star Kepler 444, suggesting that Earth-sized worlds formed in the early universe.

AstronomyRocky planets around cool stars may have Earthlike climates
Small, rocky planets that sit close to cool stars might be able to keep spinning, creating conditions hospitable to life.
-
AstronomyLarge rocky planets excel at ocean building
Rocky planets a few times as massive as Earth may build deeper oceans – and sustain them for longer – than smaller worlds.
