Could a frozen traveler from another star system hold secrets about worlds beyond our own? Astronomers think 3I/ATLAS might. This comet, the only third confirmed interstellar object ever detected, ...

The mysterious interstellar visitor 3I/ATLAS—also catalogued as C/2025 N1—is captivating scientists after Harvard astrophysicist Avi Loeb claimed the object shows no conventional cometary jets, ...

Comet 3I/ATLAS was identified as the third confirmed interstellar object after 1I/‘Oumuamua and 2I/Borisov. At the time of its discovery, the comet was faint, with a magnitude of around 17th to 18th.

The interstellar visitor 3I/ATLAS is baffling scientists. It brightened far faster than expected near the Sun, raising questions about its internal chemistry and host system.

The finding is significant because the internal composition of 3I/ATLAS could suggest that the planetary system from which it originates has a unique chemical makeup.
