Comet 3I/ATLAS to become very active? Harvard scientist's big warning as interstellar object comes closest to Sun

Interstellar comet 3I/ATLAS is nearing its closest approach to the Sun, a point where its behavior could dramatically change. While scientists largely agree it's a comet, some, like Avi Loeb, suggest its unusual characteristics, including a potential nickel alloy composition and jet direction, hint at an artificial origin. NASA's latest high-resolution images are eagerly awaited.
