The SkyMapper telescope will commence a digital imaging survey of the entire southern hemisphere sky in the second quarter of 2014. This project aims to exploit the SkyMapper survey data to discover and characterise the oldest and most metal-poor stars in our Galaxy, constraining both the origin of the chemical elements and the star formation processes that occurred during the initial stages of our Galaxy's formation. At the same time the project will use SkyMapper and other imaging data to increase understanding of the formation of the Galactic halo and of our nearest galaxy neighbours, the Magellanic Clouds.

SkyMapper望远镜将于2014年第二季度开始对整个南半球天空进行数字成像调查。该项目旨在利用SkyMapper巡天数据，发现和鉴定银河系中最古老和最贫金属的恒星，限制化学元素的起源和银河系形成初期发生的星星形成过程。与此同时，该项目将使用SkyMapper和其他成像数据，以增加对银河系晕和我们最近的星系邻居麦哲伦云的形成的理解。
