Astronomers have long sought to determine the 3-dimensional structure of our Galaxy, the Milky Way, with limited success owing to its immense size and obscuration by dust at optical wavelengths. We know more about structure of tens of thousands of other galaxies than we do about the structure of the Milky Way on the far-side of the Galactic Centre. This program will use Australian infrastructure to make the most accurate distance measurements to date of the far-side of the Milky Way visible from the Southern hemisphere, completing the 3-dimensional picture of our Galaxy. These results will be leveraged to yield accurate distances, providing fundamental information on the stellar masses, luminosities, and ages.

长期以来，天文学家一直试图确定我们银河系的三维结构，但由于其巨大的尺寸和光学波长的尘埃遮蔽，成功有限。我们对成千上万个其他星系的结构的了解，比我们对银河系中心远端的银河系结构的了解还要多。该计划将利用澳大利亚的基础设施，对南半球可见的银河系远端进行迄今为止最精确的距离测量，完成我们银河系的三维图像。这些结果将被用来产生准确的距离，提供有关恒星质量，光度和年龄的基本信息。
