This project seeks to measure a radio signal for the first time, using the Murchison Widefield Array telescope and a novel technique involving the Moon, to learn what luminous objects dominated the early Universe. There is an entire period in the early Universe that remains unobserved because familiar objects such as stars and galaxies have yet to form. One of the few observables from this period, and the time directly following it, is the radio signal emitted by neutral hydrogen atoms. Innovative analysis techniques may be developed and new training pathways for astronomers should be initiated. The Project aims to raise Australia’s scientific profile and engage the public, promoting astronomy by making results accessible and using the Moon as a familiar foundation.

该项目旨在首次测量无线电信号，使用Murchison Widefield Array望远镜和一种涉及月球的新技术，以了解早期宇宙中的发光物体。在早期宇宙中有一整个时期仍然没有被观察到，因为熟悉的物体，如恒星和星系还没有形成。中性氢原子发出的无线电信号是这一时期以及紧随其后的时期的少数几个可观测到的信号之一。可以开发创新的分析技术，并为天文学家开辟新的培训途径。该项目旨在提高澳大利亚的科学形象，吸引公众参与，通过提供成果和利用月球作为熟悉的基础来促进天文学。
