Science Corner Comet 3I/ATLAS

Comet 3I/ATLAS has reappeared.

Comet 3I/ATLAS is an interstellar object that was discovered in July 2025 by the Asteroid Terrestrial-impact Last Alert System (ATLAS) in Chile. It is the third known interstellar comet and consists of an icy nucleus and a cloud of gas. And on the 5th of November Comet 3I/ATLAS reappeared and has changed colour for the third time as it peeks out from behind the sun.
