摘　　要：“Are we alone in the universe?”This fundamental question is as old as humankind itself.Since the dawn of civilization,humanity has wonderedwhether there is life elsewhere in the universe and,if so,whether it is hosted on a second Earth.The discovery of the first extrasolar planet(also called an exoplanet),51 Pegasi b,around a sun-like star in 19951 dramatically changed our understanding of the extrasolar planet worlds and challenged the uniqueness of our solar system.Mayor and Queloz were awarded the Nobel Prize in physics in 2019 for thismajor achievement.
