New class of exoplanet! Half-rock, half-water worlds could be abodes for life


A new type of exoplanet — one made half of rock and half of water — has been discovered around the most common stars in the universe, which may have great consequences in the search for life in the cosmos, researchers say.

Red dwarfs are the most common type of star, making up more than 70% of the universe’s stellar population. These stars are small and cold, typically about one-fifth as massive as the sun and up to 50 times dimmer.
