Excellent science is going on to understand the dark ages of the universe. Using things like arrays of cheap TV antennae in China, or dipoles in western Australia, astronomers are trying to image the time when the universe was dominated by neutral hydrogen. 21 cm waves – the TV band – are the key. Stay tuned for results!
