"3I/ATLAS, named for the Asteroid Terrestrial-impact Last Alert System, has occupied an outsized place in the public imagination, including sincere discussion that it could be alien technology."
"The comet's tail pointed toward the sun rather than away from it, raising questions about its behavior and origins, with its nucleus estimated to be between 440 meters and 5.6 kilometers wide."
On December 19, 2025, the interstellar comet 3I/ATLAS made its closest approach to Earth, at a distance of 270 million kilometers. This comet, first detected on July 1, captured public interest due to its unusual features, including a tail that pointed toward the sun. NASA and other space agencies reprogrammed spacecraft to observe it. Speculation about its origins and even the possibility of alien technology emerged, fueled by a temporary information vacuum during NASA's funding crisis.
