Rumors of an incoming alien assault invaded some social media feeds in late July 2025 after the New York Put up revealed an article a few potential “alien probe.”
Whereas the article solely stated the article in query “may” be an alien probe, posts on social media described the scenario with much more alarm.
For instance, an Instagram put up (archived) with 15,000 likes warned of an “intergalactic object” that was “most certainly” an alien ship heading towards Earth. A Fb put up (archived) with 12,000 reactions sarcastically stated an astrophysicist was “sure” the article was an alien ship, a declare many within the feedback appeared to take at face worth. An X put up (archived) considered greater than 1.4 million instances claimed a hostile alien ship was headed for Earth throughout the subsequent three months. A TikTok video (archived) claimed that scientists stated a “harmful alien ship” was heading towards Earth and would arrive throughout the yr.

The declare was false. Scientists didn’t warn that an “intergalactic” object was “most certainly” or “definitely” an alien ship heading towards Earth. The overwhelming scientific consensus was that the article was probably an interstellar comet. A couple of scientists revealed a paper analyzing a theoretical argument that it could possibly be an alien ship, however even the paper’s authors believed it to most certainly be a comet.
On July 1, 2025, scientists found 3I/ATLAS, an interstellar object each NASA and the European House Company have known as a comet. (An “interstellar” object is one which travels between star methods, tons of of billions of which will be discovered within the Milky Manner galaxy alone. An “intergalactic” object travels between galaxies, and subsequently such an object by definition should originate exterior the Milky Manner.)
The concept the article was an alien ship got here from misunderstandings and misrepresentations of a paper titled “Is the Interstellar Object 3I/ATLAS Alien Know-how?” by Harvard astrophysicist Abraham “Avi” Loeb and two researchers from the UK. However regardless of the title of the paper, which had not been peer-reviewed by the point it unfold on social media, the paper’s authors didn’t consider the reply to the query within the title was “sure.”
“By far the most certainly final result will likely be that 3I/ATLAS is a very pure interstellar object, in all probability a comet, and the authors await the astronomical knowledge to help this probably origin,” wrote the scientists within the paper’s conclusion.
Within the paper’s introduction, the authors wrote that one of many causes for analyzing the speculation that the comet may really be alien expertise was that “The speculation is an fascinating train in its personal proper, and is enjoyable to pursue, no matter its probably validity.”
The scientists wrote that if the article was alien expertise, its intentions could be both innocent, malicious or someplace in between. As a result of humanity would wish to do nothing if an alien craft had innocent intentions, based on the paper’s authors, the likelihood that it could possibly be malicious could be of extra concern. Thus, the paper assumed the article could be harmful to people if it have been an alien ship.
After its discovery of the article, NASA stated on an informational webpage that 3I/ATLAS would “stay distant” and pose “no menace to Earth.”
The speculation that 3I/ATLAS may attain Earth by November wasn’t based mostly on the present projected path of the article. As an alternative, the authors of the paper estimated the arrival time based mostly on maneuvers a theoretical alien ship may make utilizing the gravity of the Solar or Jupiter to launch such a ship within the course of Earth.
This was not the primary time that Loeb, the Harvard astrophysicist, tried to encourage different scientists to contemplate the unlikely speculation that an interstellar object could possibly be of synthetic origin. In 2017, after the invention of the primary recorded interstellar object to enter the photo voltaic system, Loeb advised The Guardian, “Most probably it’s of pure origin, however as a result of it’s so peculiar, we want to test if it has any signal of synthetic origin, resembling radio emissions.”
