A Harvard astrophysicist has sparked widespread curiosity online by warning people to “take vacations before October 29,” suggesting that NASA may be withholding critical information about a mysterious interstellar object passing through our solar system. Designated 3I/ATLAS, this visitor has captured global scientific attention due to its unusual size, estimated at roughly 5.6 kilometres across, extraordinary speed, and puzzling trajectory. Unlike typical interstellar objects, it emits nickel tetracarbonyl, a compound previously known only from industrial processes on Earth, and lacks detectable iron, further deepening the mystery.
