B A new study focuses on K2-18b, an exoplanet(系外行星) like the Earth discovered in 2015, orbiting a red dwarf star(矮星) close enough to receive about the same amount of radiation from its star as the Earth does from the sun."Studies have suggested that planets with hydrogen-rich at...
Water vapour in the atmosphere of the habitable-zone eight-Earth-mass planet K2-18 bAstrophysics - Earth and Planetary AstrophysicsIn the past decade, observations from space and ground have found H _2 _2 O to be the most abundant molecular species, after hydrogen, in the atmospheres of hot...
Here, we report the detection of a spectroscopic signature of water in the atmosphere of K2-18 b—a planet of eight Earth masses in the habitable zone of an M dwarf7—with high statistical confidence (Atmospheric Detectability Index5 = 5.0, ~3.6σ (refs. 8,9)). In addition, the ...
