Okay, space fans, get this: there’s a new interstellar object, 3I/ATLAS, cruising through our solar system—and it might be glowing on its own. Most comets just reflect sunlight, but this one’s got a weird, flashlight-like glow and no tail. Harvard’s Avi Loeb is already floating the wild theory that it could be a nuclear-powered alien spacecraft falling apart after eons in space. NASA’s keeping an eye on it as it swings by Mars this fall. Sci-fi writers, start your engines! #Science #space #aliens
