Super-Earths Orbiting Orange Stars May Be More Habitable Than Earth
Worlds More Habitable Than Earth? They're Out There
Astrobiologist Iva Vilović found that garden cress grew faster under simulated K-dwarf starlight than under sunlight, suggesting photosynthesis can occur on planets around these cooler, slower-burning stars. Scientists propose that super-Earths orbiting K-dwarfs—about 20-30% wider and twice as massive as Earth—could be 'superhabitable,' with thicker atmospheres, stronger magnetic fields, and stable climates that support more complex and diverse life than on Earth.
K-dwarf light is a very, very interesting light source, and it should be considered, if not prioritized, for any type of search for extraterrestrial life, in my opinion.
