NASA Cut the Feed as 3I/ATLAS Passed Through

When 3I/ATLAS was first detected in July 2025 by the ATLAS survey in Chile, astronomers noticed something extraordinary. Its orbit was not just elongated—it was hyperbolic, meaning it was not bound to the Sun like typical planets, comets, or asteroids.

Instead, it was simply passing through the Solar System. This marked only the third confirmed interstellar object ever observed, following ‘Oumuamua in 2017 and Borisov in 2019. Yet 3I/ATLAS stood apart. Traveling over 210,000 kilometres per hour, it became the fastest object of its kind ever recorded.

Its trajectory brought it surprisingly close—1.36 astronomical units from the Sun and about 1.8 AU from Earth, roughly 267 million kilometres. Early observations stunned scientists: its light signature did not match any known comet or asteroid. It appeared unusually reflective, highly structured, and remarkably stable under solar radiation. Whatever 3I/ATLAS is, it remains unlike anything previously seen.
