Description

Our Sun might seem vast, but it is a mere speck compared to the colossal giants inhabiting our universe. We’re exploring the behemoth stars that defy our understanding of scale, from rare Wolf-Rayet monsters to red supergiants like UY Scuti. Discover the physics of how these giants evolve and the ultimate limit of how large a star can actually get.
