The Hubble Deep Field spent thousands of hours looking at a tiny patch of sky, revealing countless galaxies. But there's an earlier epoch, when the first stars formed, known as Cosmic Dawn, and it's beyond reach with today's telescopes. When the Square Kilometre Array (SKA) comes online in a few years, it could finally be the instrument to see that early time in the Universe. Researchers simulated 1000 hours of SKA observations, its own deep field, and hope to reveal it.
