Interstellar Comet 3I/ATLAS Observed by Mars Orbiters
A visitor from another star In late 2025, Earth’s telescopes were chasing light from a visitor that didn’t belong to our solar system. 3I/ATLAS is not a typical comet born in the icy outskirts of the Sun’s domain; it arrived from another star and is currently just a fleeting guest in our celestial neighborhood. Discovered…

ESA’s ExoMars and Mars Express Observe Interstellar Comet 3I/ATLAS
ESA’s Mars Orbiters Turn Their Eyes on a True Interstellar Visitor In a surprising turn for planetary science, Europe’s ExoMars Trace Gas Orbiter (TGO) and Mars Express have recorded observations of the interstellar comet 3I/ATLAS. While the nucleus remains far too faint to resolve, the coma surrounding the comet’s icy-rocky core becomes visible in CaSSIS…

European Mars Orbiter Spies Interstellar Comet 3I/ATLAS Zooming Past Red Planet
Overview: A Rare Interstellar Visitor Near Mars In a remarkable observational feat, a European Mars orbiter recorded imagery of the interstellar comet 3I/ATLAS as it whizzed past Mars on October 3. The flyby brought the comet to within about 19 million miles (30 million kilometers) of the Red Planet, providing scientists with a rare chance…
