概要

It is a star so enormous that it breaks the human imagination. If Betelgeuse replaced our Sun, its surface would stretch past Mars — swallowing Earth, Venus, Mercury, and even the asteroid belt.

In this episode, I reveal the true size of Betelgeuse, the red supergiant marking Orion's shoulder. For decades, measurements have varied wildly because this star breathes. It pulsates. It changes shape. Current estimates place its radius between 640 and 1,180 times that of our Sun. That means over 1.6 billion Suns could fit inside it. But here is what makes Betelgeuse terrifying: its edge is not solid. It is a diffuse, churning envelope of gas so thin that astronomers struggle to define where the star ends and space begins. Based on interferometry, Hubble imagery, and 2023 updates from the European Southern Observatory, this episode separates fact from fiction about the cosmic giant that could go supernova — tonight, or in 100,000 years. Turn down the lights, put on your headphones, and press play — because size is not just a number. It is a warning.
