Interstellar comet 3I/ATLAS is carrying chemical signatures that do not match anything formed in our solar system.

China’s Tianwen-1 orbiter captured a faint but remarkable view of 3I/ATLAS as the interstellar comet raced past Mars. The ...

In the latest research, telescope observations of 3I/ATLAS examine its chemical structure and suggest that it took shape in a peripheral region of a relatively calm planetary system ...

One year ago, on July 1 2025, astronomers discovered a fascinating new object moving through the Solar System. Detected by the Asteroid Terrestrial-impact Last Alert System (ATLAS), the object was ...

Comet 3I/ATLAS arrived from beyond the Solar System carrying a chemical story unlike anything astronomers had measured before. In the gas around it, they found isotope ratios that do not match the ...

Analysis of the second confirmed interstellar comet to visit our solar system suggests that the alien body could be covered in erupting icy, volcano-like structures called cryovolcanoes. Researchers ...

Strange interstellar comet speculated to be alien spacecraft is older than Solar System - Scientists say comet represents preserved fragment of ancient planetary system ...

A mysterious interstellar object known as 3I Atlas is crossing our Solar System, and the more scientists observe it, the ...

Interstellar object characterisation and dynamics encompass the detection, physical and chemical analysis, and orbital modelling of bodies originating beyond the Solar System. Observational campaigns ...
