Астрономы впервые обнаружили атмосферу у экзопланеты, похожей на Землю и находящейся в обитаемой зоне. Планета LHS 1140 b может быть пригодна для жизни, но её состав и наличие океанов пока остаются неясными.
Studies have shown that moons ejected from their planetary systems by rogue planets can maintain life-friendly conditions for billions of years thanks to tidal heating. This expands our understanding of where life might exist in the Universe.
A new study has shown that hycean worlds—water-rich exoplanets with vast oceans—are much rarer than previously believed, due to water loss from chemical processes. This finding casts doubt on the existence of worlds where oceans make up a significant portion of their mass.
