LuSEE-Night is set to make history for its ability to reach-and survive in-an inhospitable place where there's enough radio silence for the Dark Ages Signal to be detected: the lunar far side. LuSEE-Night is a remarkable concept for a radio telescope that will be developed in collaboration between NASA and DOE, with Brookhaven Lab leading DOE's role in the project and DOE's Lawrence Berkeley National Lab providing key technical support. Now, a new project called the Lunar Surface Electromagnetics Experiment-Night (LuSEE-Night) aims to access the Dark Ages Signal for the first time. And if predictions based on each benchmark don't match, that means we've discovered new physics." The Dark Ages Signal would provide a new benchmark. "So far, we can only make predictions about earlier stages of the universe using a benchmark called the cosmic microwave background. We can calculate almost everything exactly," said Brookhaven physicist Anze Slosar. "Modeling the universe is easier before stars have formed. If cosmologists could detect radio waves from the Dark Ages-what is known as the "Dark Ages Signal"-they could help uncover answers to some of the universe's biggest mysteries, such as the nature of dark energy or the formation of the universe itself. Though radio waves from the Dark Ages still linger in space, the abundance of radio interference on Earth has masked these signals from scientists seeking to study them. It's a point in time that scientists have never been able to observe. There were no stars or planets in the Dark Ages. The Dark Ages are an early era of cosmological history starting about 380,000 years after the Big Bang. If successful, the project will mark the first step towards exploring the Dark Ages of the universe. Department of Energy's (DOE) Brookhaven National Laboratory are leading a new effort to land a radio telescope on the moon. ![]() ![]() Lunar telescope will search for ancient radio waves
