🪐 Far away in the constellation Pegasus, the exoplanet HD 209458b—nicknamed "Osiris"—boils under such intense heat from its star that its atmosphere is literally being blown away into space. Powerful ultraviolet radiation strips gases from the planet, creating a long, glowing tail of material that stretches behind it like a giant comet, showing how extreme conditions can rewrite the rules for how planets survive. ✨ #exoplanets⚡#extremes⚡#atmospheres⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels
