Instead, a faint pearly halo that only shows itself during a total eclipse turned out to be hundreds of times hotter than the surface beneath it. A mysterious green line, an element that never existed and a spacecraft that went silent on Christmas Eve all became part of the hunt for an explanation. So how does a star heat the air above it hotter than the fire?\r\n\r\nThis episode was created with artificial intelligence: AI-assisted script and AI-generated (synthetic) voice.","author_name":"Creators Obomedia"}
