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 ...
However. K2-18b's large atmosphere is extremely thick and creates high-pressure conditions, which"very likely prevents life existing on the planet's surface", a news release reads. While these researchers found evidence for liquid water clouds on K2-18b, because of its possible lack of surf...
However, a news release reads: ''K2-18b's large atmosphere is extremely thick and creates high-pressure conditions, which likely prevents life as we know it from existing on the planet’s surface. '' While these researchers found evidence for liquid water clouds on K2-18b because of its ...
【题目】Since its discovery by astronomers in 2015, the exoplanet K2-18b has caused much excitement. About 110 light years away from Earth, the distant world sits not close enough to its host star to be too hot and not far enough away to be too cold, so that liquid water could flow ...
