A Harvard professor and two researchers have suggested that a strange object flying through our solar system might be an alien spacecraft—and could pose a threat to Earth as soon as November 2025.
The object, called 3I/ATLAS, was discovered earlier this year. It is the third known interstellar object to pass through our solar system. Astrophysicist Avi Loeb from Harvard University, along with Adam Hibberd and Adam Crowl from the Initiative for Interstellar Studies, believe the object could be artificial and possibly designed by intelligent life.
Unusual Path and Speed Raise Concerns
The team says 3I/ATLAS is moving very fast and has a strange flight path. It will pass near planets like Venus, Mars, and Jupiter, which the researchers believe could let it plant surveillance devices.
They also warn that during its closest approach to the Sun in late November, the object will be hidden from Earth-based telescopes. This may give it a chance to change direction or perform maneuvers without being seen.
Could It Be Natural?
Many scientists believe the object is likely a comet or asteroid. But Loeb and his team point out that 3I/ATLAS does not show signs of comet activity, like a tail or glowing gas. They say this makes the object more mysterious.
The team says if the object shows unexpected movement or speed changes between November 21 and December 5, it could support the theory that it is an alien probe. If it turns out to be hostile, they say defensive action may be needed.
Scientific Community Reacts
The idea has caused debate and doubt in the scientific community. Many experts say there is not enough evidence to support the alien theory. The research has not yet been peer-reviewed and remains under investigation.
This is not the first time Professor Loeb has made bold claims. In 2017, he suggested that another interstellar object, called ʻOumuamua, could also be alien technology.
For now, the object is being closely watched. Scientists hope that more data and observations will help confirm whether 3I/ATLAS is natural—or something else.
