Space just got weirder. The interstellar object 3I/ATLAS is making its closest pass to Earth tonight, and scientists are baffled. Its 'heartbeat'—a pulsing light pattern—keeps changing, and some say it matches ancient cosmic calendars. NASA insists it’s just a comet, but others think it could be something more, maybe even broadcasting a universal math code. You can actually spot it with a backyard telescope tonight. Is this just a space rock, or are we missing something huge? #Science #3IATLAS #SpaceMystery
