While experts like Avi Loeb have raised intriguing possibilities, NASA confirms the definitive news: 3I/ATLAS poses 'no threat' to Earth.

While most scientists believe it’s a natural comet, one Harvard astronomer has suggested its unusual features could hint at signs of alien technology. View on euronews

According to the study, interstellar object 3I/ATLAS showcased its first sign of a non-gravitational acceleration at perihelion, or the point of closest approach to the Sun. The non-gravitational acceleration was detected at a perihelion distance of 1.36 times the Earth-Sun separation, equivalent to 203 million kilometers.

Harvard astrophysicist Avi Loeb is fiercely demanding that NASA release high-resolution images of the interstellar object 3I/ATLAS.

Interstellar comet 3I/Atlas is nearing the sun, sparking debate due to Harvard professor Avi Loeb's theory that it could be an alien spacecraft. While Loeb suggests its trajectory and timing near the sun might indicate artificial intelligence,

Abi Loeb has hit out at NASA over the interstellar object 3I/ATLAS, as he said they were ‘pretending to be the adults in the room’

Interstellar object 3I/ATLAS reaches its perihelion, prompting Harvard's Avi Loeb to suggest it's an 'alien mothership.' Learn about his 'acid test' theory and his warning that 3I/ATLAS could release 'mini-probes' toward Earth as 'Christmas gifts' on 19 December 2025.

As interstellar comet 3I/ATLAS races away from the Sun, astronomers are working to decode its story. Each observation adds to the understanding of how matter travels between star systems, carrying with it the potential ingredients for life.
