Science For Sleep | Behemoth — Is This the Largest Star in the Universe?

Some stars stretch the idea of size until it almost breaks. In this episode, Behemoth — is this the largest star in the universe becomes a quiet examination of how astronomers measure stellar giants and why a single answer is so difficult to pin down. These enormous stars swell far beyond normal suns, their outer layers thin and drifting, their brightness changing as they shed mass into space. What looks like a single object can be a vast, unstable region of glowing gas, expanding and contracting over time. Size, it turns out, depends on how you choose to define the edge of a star. Let this calm reflection on whether Behemoth is the largest star in the universe soften your sense of scale. Breathe slowly. Let the idea of a star larger than planetary orbits drift past without effort. And rest in the stillness of a universe where even its biggest lights burn gently, far away.
