NASA and ESA say 3I/ATLAS poses no threat to Earth. We explain its nickel-heavy readings, IAWN’s training drill, and why the Harvard alien claim lacks proof.

A newly discovered "quasi-moon" near Earth is causing a major stir among scientists and ... NASA is currently tracking Comet 3I/ATLAS, the third known object to arrive from interstellar space. This comet, which poses no threat, was discovered on July ...

According to him, this behavior occurs because comets heat up unevenly as they approach the Sun. The side facing the Sun warms faster, and if a weak spot gets hot enough, it can release material thousands of kilometers into space, much like a geyser, in the Sun’s direction.

While scientists are confident it is a comet, its origins have ignited wild theories, including the persistent idea that it could be an alien spacecraft. As it approaches its perihelion—its closest point to the Sun—on 29 October 2025,

In particular, one scientist has claimed it could even be an 'alien mothership', with a few key differences which he claims are 'not natural', such as releasing a metal compound never seen before in nature, or the trajectory of its particles.

Though NASA confirms that 3I/ATLAS poses no immediate threat to Earth, its unusual trajectory and behaviour have stirred concerns. Scientists ask what might occur if the object were on a collision course and how the impact could play out. The scenario remains hypothetical yet instructive for understanding cosmic risks.
