发现“超级地球”！可能存在类地生命
双语君约 3 分钟For centuries, the question of whether life exists beyond Earth has intrigued humanity, and now a joint discovery by Chinese and German scientists may offer a significant clue.
最近，科学家有了一项重要发现。由中国科学院云南天文台领衔的中德联合研究团队，在一颗类似太阳的恒星周围，找到了一颗质量为地球的十倍、可能有类地生命的“超级地球”。
Based on the Transit Timing Variation (TTV) technique for the first time, the super-Earth, Kepler-725c, with 10 times the mass of the Earth, has been detected within the habitable zone of the Sun-like star Kepler-725, which is a promising candidate for potential habitability.
"This newly discovered non-transiting planet and its host star are located at a place about 2,472 light-years from the solar system," said Gu Shenghong, team leader from the Yunnan Observatories of the Chinese Academy of Sciences.
"By analyzing the TTV signals of Kepler-725b, a gas giant planet with a 39.64-day period in the same system, the team has successfully inferred the mass and orbital parameters of the hidden planet Kepler-725c," said Sun Leilei, the first and co-corresponding author of the study, who is with the Yunnan observatories.
Gu also noted that it requires further investigation to assess whether the discovered habitable planet truly possesses conditions suitable for Earth-like life.
