This project, by a group of outstanding young observational astronomers, aims at an understanding of the properties of extremely faint galaxies. These objects dominate the universe in terms of numbers, although their contribution to the total mass is poorly known. Indeed, most of our knowledge of star formation in external galaxies, and of galaxy properties in general has come from studies of systems which may not be typical. These workers will explore the properties of these much more numerous objects by both optical and radio means. Preliminary work by these investigators has already resulted in the discovery of the two largest, most gas-rich spiral galaxies known, both systems of very low surface brightness.

这个项目，由一群优秀的青年观察员 天文学家，旨在了解的性质， 极其微弱的星系这些天体主宰着宇宙 尽管它们对总质量的贡献 鲜为人知。 事实上，我们对星星形成的大部分知识 在外部星系中，星系的性质一般来说， 来自于对非典型系统的研究。 这些 工作人员将探索这些更多的属性 通过光学和无线电手段。 前期工作 这些调查人员已经发现了 两个已知最大、最富含气体的螺旋星系， 非常低的表面亮度。
