In 1967, inside a windswept Australian outback tracking station, three dream-chasing scientists intercept the first confirmed extraterrestrial transmission—an other-worldly melody. As word spreads, a pop-obsessed DJ, an ambitious bureaucrat and an Indigenous stargazer converge on the dish, each seeking to control (or protect) the cosmic broadcast. With a score that fuses vintage surf-rock, soaring orchestral chorales and pulsating synthwave, Celestial Radio explores who owns discovery—and how one haunting song can unite or divide a planet.
