It comes from beyond the stars,

crossing the endless interstellar void,

only to leave a fleeting trail of light in our night sky.

In the autumn of 2025, the third interstellar visitor — Comet 3I/ATLAS —

is sweeping through our Solar System.

Let us capture this encounter across the cosmos together.

Every image is humanity’s first gaze upon a traveler from the stars.
