Say hello to JADES-GS-z13-1, a galaxy seen just 330 million years after the Big Bang. That’s over 13 billion years ago, when the cosmos was still wrapped in a thick fog of neutral hydrogen — a veil that should have blocked any bright ultraviolet light from reaching us. But here’s the twist: Webb detected a surprisingly strong glow of Lyman-α radiation — a specific kind of light emitted by hydrogen atoms that shouldn’t have been able to escape through that fog at such an early time.
