Interstellar Visitor 3I/ATLAS Shrinks Mysteriously Before Earth Approach

On November 10, 2025, new images have revealed that the interstellar visitor 3I/ATLAS has mysteriously shrunk in size in the weeks leading up to its closest approach to Earth on December 19. NASA recently calculated that 3I/ATLAS has shed 13% of its material after passing the sun last month.

Harvard Professor Avi Loeb, who has been analyzing the object since the summer, noted that this sudden shrinkage was directly tied to a noticeable change in the interstellar object's course as it moved closer to the sun. Loeb has previously warned that contact with 3I/ATLAS has the makings of a 'black swan event,' meaning this massive space object could be an alien mothership trying to disguise itself as a space rock for an unknown purpose.

Despite NASA and hundreds of researchers insisting 3I/ATLAS is nothing more than a comet from outside our Solar System, Loeb argues the object has displayed at least 10 strange anomalies that suggest an artificial, extraterrestrial origin. These include the lack of a cometary tail and the object's repeated color changes, which are highly unusual for a typical comet. With the latest images showing no signs of the expected gas and dust outpouring, Loeb maintains the odds of 3I/ATLAS being an alien craft are growing every day.
