天文学家在岩石系外行星LHS 1140-b周围探测到了大气层，这标志着搜寻地外生命取得了重大突破。这是首次在恒星宜居带内的岩石行星上确认存在大气层，这是支持生命的关键条件。这颗行星距离地球48光年，质量约为地球的5.6倍，其大气层主要由氦组成，是使用WINERED光谱仪探测到的。 AI

影响这项发现通过确认岩石系外行星宜居性的一个关键条件，推进了对地外生命的搜寻。

科学家发现行星拥有“类似地球生命”所需的一切，取得突破性进展

For the first time, scientists found that a rocky planet in the habitable zone of its star has an atmosphere. It’s the best place to look for alien biosignatures, scientists say.
