    How it works

      The 21 cm radio wave is a low-frequency signal that emanates from the early universe, around 380,000 years after the Big Bang. This turbulent period saw the first generation of stars being formed, and the universe expanding rapidly. As a result, the photons from this era traveled a vast distance, interacting with the electrons in the intergalactic medium, causing the signal to shift and become detectable on Earth. To decode this signal, scientists use highly sensitive radio telescopes, like the Square Kilometre Array (SKA), to collect and process the data.
