ORMOUS 🌒 on Instagram: "Betelgeuse Supernova? The red supergiant Betelgeuse (≈550–700 light-years away, ~700–900× the Sun’s size) will one day explode as a Type II supernova. When it does, it could shine as bright as — or brighter than — the full Moon, even visible in daylight for weeks. The timing is unknown: it might happen tomorrow, or anytime in the next 100,000 years. Spectacular to see, but safely distant — Earth faces no danger."
