James Peebles、Michel Mayor和Didier Queloz 3位科学家分享了2019年诺贝尔物理学奖，以表彰他们对宇宙学和系外行星的发现做出的贡献。介绍了Mayor和Queloz两位诺贝尔物理学奖获得者的学术经历，简述了系外行星领域的发展及现状，解读了太阳系外行星首次发现的科学意义，论述了视向速度法探测系外行星的原理和发展过程，介绍了该领域在中国的研究进展，并对未来进行了展望。
A half of the Nobel Prize in Physics 2019 was awarded jointly to Michel Mayor and Didier Queloz for the discovery of an exoplanet orbiting a solar-type star. In this paper we review the academic achievements of these two scientists, the scientific significance of this important discovery, and the future development of this research area in China.
