In a hushed clean room, engineers raise the silver-veined heart of NASA's COSI telescope—a detector box destined to hunt the most violent light in the universe. Gamma rays don't bounce off mirrors; they smash into detectors, and COSI will trace their Compton-scattered paths back to dying stars, hungry black holes, and the mysterious positron cloud at our galaxy's core. When this instrument finally opens its eyes, it won't just take pictures—it will listen to the nuclear heartbeat of the cosmos, reading the afterglow of creation itself. It's a reminder that the universe speaks in frequencies our senses never evolved to hear—and that we're building better ears.
