1995 marked astronomical history with the detection of the first planet outside the solar system. A decade later, more than 200 exoplanets have been detected indirectly by measuring the tiny wobble movement of the star induced by the gravitational influence of a revolving planet. While these discoveries have greatly advanced our knowledge of exoplanets in general, progress remains limited by our inability to take direct images of these fascinating objects. Direct imaging of exoplanets, though very challenging, will help understand their nature and determine their frequency in the solar neighbourhood. The ultimate goal of this endeavour is to determine the ubiquity of the solar system and the prevalence of life in the universe.

1995年，天文学家发现了太阳系外的第一颗行星。十年后，通过测量由旋转行星的引力影响引起的星星的微小摆动运动，已经间接发现了200多颗系外行星。虽然这些发现极大地推进了我们对系外行星的总体了解，但由于我们无法直接拍摄这些迷人物体的图像，进展仍然受到限制。对系外行星的直接成像虽然非常具有挑战性，但将有助于了解它们的性质并确定它们在太阳附近的频率。这项努力的最终目标是确定太阳系的普遍性和宇宙中生命的普遍性。
