In October 2025, two European Space Agency missions — ExoMars TGO and Mars Express — turned their eyes to the heavens to witness a cosmic traveler unlike any other: Comet 3I/ATLAS, an interstellar visitor billions of years older than our Solar System.
Captured from orbit around Mars, this rare encounter reveals the first close look at a comet that comes from far beyond the Sun’s reach. As its icy body begins to awaken under the warmth of the Sun, scientists race to uncover its secrets — what is it made of, and what stories does it carry from distant worlds?
Join us as we explore how this faint, ancient comet connects us to the wider galaxy and marks a new chapter in humanity’s search for knowledge beyond our Solar System. 🌌
