The interstellar comet 3I/ATLAS has a thick irradiated crust that no longer resembles its home star system, simulations and James Webb Space Telescope observations have found.

The comet could be older than our solar system. The comet is also distinct because nickel vapor was detected in the gas surrounding it.

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,

Astronomers have identified Comet 3I/ATLAS as an interstellar object, making it only the third confirmed visitor from outside our solar system, according to NASA.<br /><br />The comet is travelling on a hyperbolic trajectory,

Interstellar comet 3I/ATLAS baffles scientists, brightening 7x faster and turning blue. A Harvard expert suggests its strange path is a 'possible hint of design'.

Physicist Michio Kaku is warning about the AI-generated deepfakes, which exploit his image to push the idea the comet '3I/ATLAS' is an alien spacecraft that poses a potential threat.

Almost 50 years after the WOW! signal stunned astronomers in Ohio, 3I/Atlas reappears in the same sky region, raising questions about extraterrestrial activ
