Astronomers across the world are preparing for a rare celestial showdown as interstellar comet 3I/ATLAS races towards its closest encounter with the Sun this week. The mysterious visitor, which originated from deep beyond our Solar System, is now on course for what scientists call perihelion—the moment it skims nearest to the Sun's surface.
According to NASA, 3I/ATLAS will come within 1.4 astronomical units of the Sun, enduring extreme radiation and powerful gravitational forces that could shatter an ordinary comet. But this isn't just another cosmic flyby. Experts say the event could reveal whether this alien object is a natural ice body or something far more extraordinary—perhaps even a product of interstellar engineering.
