Water found in atmosphere of planet beyond our solar system

Posted by in category: space

LONDON (Reuters) — Scientists for the first time have detected water in the atmosphere of an Earth-like planet orbiting a distant star, evidence that a key ingredient for life exists beyond our solar system, according to a study published on Wednesday.

Water vapor was found in the atmosphere of K2-18b, one of hundreds of “super-Earths” — worlds ranging in size between Earth and Neptune — documented in a growing new field of astronomy devoted to the exploration of so-called exoplanets elsewhere in the Milky Way galaxy.

More than 4,000 exoplanets of all types and sizes have been detected overall.
