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...
landing on the planet would also be nearly impossible, especially because the gas is so thick and has such an incredibly high pressure that any earth-created space-craft sent there would be devastated.可知,如果没有一个真实的表面,在K2-18b上着陆几乎是不可能的,因为K2-18b上的气体非常厚,压强大...
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...

Every fraction of a degree of global heating impacts the future of life on Earth. This report shows that in 2023 we came perilously close to the global temperature temporarily rising 1.5 degrees Celsius above pre-industria...
CHARACTERIZING K2 PLANET DISCOVERIES: A SUPER-EARTH TRANSITING THE BRIGHT K DWARF HIP 116454doi:10.1088/0004-637X/800/1/59American Astronomical Society
This star is one of only seven with masses less than 0.2 known to host transiting planets, and the planet appears to be a slightly smaller analogue of GJ 1214b ( ). Our new Spitzer observations were taken two years after the original K2 discovery data and have a significantly higher ...
