Human interest in the possibility of other worlds in the Universe has existed for over two millennia. In recent centuries, this question has been translated into the following terms: Are there planetary systems linked to stars other than the Sun?Developments in astronomical instrumentation have transformed this philosophical dream into a new, vibrant chapter in astronomy. This article describes my journey that started over 40 years ago with the exploration of the dynamics of our Galaxy, that brought astonishing scientific progress to which my collaborators and I have contributed, and eventually led to the amazing discovery of the plurality of worlds.

 多个世界


人类对宇宙中其他世界的可能性的兴趣已经存在了两千多年。近几个世纪以来，这个问题被翻译成以下术语：除了太阳之外，是否有与恒星相关的行星系统？天文仪器的发展将这个哲学梦想变成了天文学中充满活力的新篇章。这篇文章描述了我从 40 多年前开始的探索银河系动力学的旅程，它带来了惊人的科学进步，我和我的合作者为此做出了贡献，并最终导致了对多元世界的惊人发现。
