A | 研究人员发现，六光年之外的巨型超级地球行星可能有简单的生命。巴纳德B（或GJ699B）是一颗最近发现的绕巴纳德轨道运行的超级地球行星，它是离地球最近的第二颗恒星。巴纳德B被认为是极冷的，其温度与欧洲相似，大约在零摄氏度以下150度。但研究人员说，它的铁/镍“核心”温度相当高，地热活动非常强烈。维拉诺瓦大学的天体物理学家爱德华·桂南在美国天文学会的一次会议上说：“地热能支持地下生命带，就像南极洲的地下湖泊一样。
B | ”“我们知道，欧罗巴的表面温度与巴纳德B的相似。但是由于地热条件，液态水可能会在木卫二冰冷的表面下。如果存在水，地热可能会导致冷地表下存在液态水的“生命带”。
Mohammad Abdi (R) learns about TCM herbal drinks from a doctor at Ningxia Chinese Medicine Research Center in Yinchuan, northwest China's Ningxia Hui Autonomous Region, on Aug. 15, 2026. Mohammad Abdi, a 26-year-old Iranian student, came to China in 2023 to study clinical medicine at Ningxia Medical University. He was introduced to traditional Chinese medicine (TCM) at an early age. After seeing his uncle receive cupping therapy in Iran, he became curious about this traditional medical practice. Later, as a medical student in China, he had the opportunity to take professional TCM courses. On weekends, Abdi visits Ningxia Chinese Medicine Research Center to experience various TCM therapies. "I was a gym rat, so I initially thought TCM practices were too simple to be effective," he said. However, as he learned more about TCM, he was impressed by its depth and effectiveness. He recommended Baduanjin, a traditional Chinese breathing and stretching exercise, to his fellow international students, while he especially enjoys tuina massage combined with cupping therapy, which helps relieve the stress of his studies and clinical internship. For Abdi, TCM is more than a way to treat diseases; it is also a health philosophy that can be integrated into daily life. He believes ordinary people can benefit from TCM-based wellness practices, while professional doctors can use TCM techniques to treat patients. TCM is now expanding its global presence and joining the worldwide conversation on health and lifestyle. Inspired by growing interest in Chinese lifestyles overseas, Abdi hopes to continue exploring TCM and become a skilled doctor, helping more people in his hometown benefit from traditional Chinese medicine.

。这种情况与结冰的欧罗巴非常相似。
C | ”我们已经把注意力集中在巴纳德身上一段时间了，”约拿说。发现巴纳德B行星最重要的意义是在离太阳最近的两个恒星系统中都有行星。”这支持了先前基于开普勒望远镜数据的研究，即行星在银河系中普遍存在，甚至有数百亿个行星。恩格尔说：“巴纳德B被认为是一颗质量超过地球三倍的岩石行星。巴纳德的寿命大约是太阳的两倍。它已经存在了大约90亿年前，太阳存在了46亿年前。宇宙中的一些行星，即地球的大小，在地球上，甚至在太阳上存在了很长一段时间。巴纳德B的质量是地球的三倍多，其轨道半径与水星的大致相同，在巴纳德（红矮星）周围有233天的轨道周期。
D | 朱纳说，虽然亮度很低，但将来可能用一个很大的望远镜“拍摄”巴纳德B，“这样的观测将揭示大气、表面和宜居性的特性。”虽然表面温度在零下150度左右，但科学家相信冰下有液态水可以维持生命。
E | 巴纳德B被认为是一颗岩石行星，比地球大至少3.2倍。巴纳德B号的主恒星巴纳德距离地球6光年，在天文尺度上距离很短，亮度只有太阳的0.0035倍。
F | 离地球最近的唯一恒星系是半人马座阿尔法星，距离地球约4光年。
