过去几千年人类对行星认识的范围仅仅局限在太阳系内,而数目也仅仅不到十颗。从上世纪末到现在短短的二十来年,人类已经发现了成千上万颗太阳系外行星。古老的行星科学向人们展现了它新的面孔,把人们从太阳系内带到了太阳系外。文章首先简要回顾了人类探索行星的历史,然后介绍太阳系外行星领域的一些重要进展及热门的研究话题,最后谈及对该领域未来的展望和期待。
過去幾韆年人類對行星認識的範圍僅僅跼限在太暘繫內,而數目也僅僅不到十顆。從上世紀末到現在短短的二十來年,人類已經髮現瞭成韆上萬顆太暘繫外行星。古老的行星科學嚮人們展現瞭它新的麵孔,把人們從太暘繫內帶到瞭太暘繫外。文章首先簡要迴顧瞭人類探索行星的歷史,然後介紹太暘繫外行星領域的一些重要進展及熱門的研究話題,最後談及對該領域未來的展望和期待。

For thousands of years, our knowledge of planet has been confined within the solar system, which contains only a handful of known planets. Since 1990s, people have made enormous progress in the last 20 years. Thousands of extra-solar planets (exoplanets) have been detected, opening a new era for planetary research and extending our scope beyond the solar system. In this article, we briefly review the history of planetary research, introduce some key progress and hot topics in the field of exoplanet, and discuss its prospects in the near future.
