We dive into UY Scuti, one of the universe’s biggest stars, and ask: just how big is it? We explore radius estimates that range from about 900 to 1,700 solar radii, and why distance and dust make the numbers stubbornly uncertain. We'll follow its dramatic life—pulsations, prodigious mass loss into a vast circumstellar shroud, and a likely fate in a core-collapse supernova—told through the challenges of measuring giants thousands of light-years away.
