Much progress has been made during the past decade in observations of interstellar clouds of gas and dust and of the formation of new stars that takes place in cold, dense clumps in many of these clouds. The question that is unanswered is "Do any of these currently forming stars acquire planetary systems similar to our own?" The question is unanswered because up to now observers lacked the angular resolution to detect planets or planetary precursor object across interstellar distances. The Principal Investigator proposes to overcome this difficulty by using lunar occultations of star forming regions, which he thinks will increase the angular resolution sufficiently to allow him to observe planetary systems in the making.

在过去十年中， 星际气体和尘埃云的观测， 新恒星的形成发生在寒冷，密集的团块中， 很多这样的云。 没有答案的问题是“做任何 在这些正在形成的恒星中， 和我们的相似吗“这个问题没有答案，因为 现在观测者缺乏探测行星的角分辨率， 行星前体物体穿越星际距离的 主要研究者建议通过以下方式克服这一困难： 利用月球对星星形成区域的掩星， 将增加角分辨率足以让他 观察正在形成中的行星系统
