How an Ancient Ice Age Carved Deep Scratches on Mars
Unveiling an Ice Age on the Red Planet For decades, scientists have grappled with questions about Mars’ climatic past. A compelling new chapter emerges from high-resolution images taken by the European Space Agency’s Mars Express orbiter. These photographs reveal long, scar-like features and deep craters that point to a dramatic period when the Red Planet…

Mars Ice Age Shaped the Red Planet’s Surface, Reveals New Data
Introduction: A Planetary Ice Age Revealed Recent high-resolution images from the European Space Agency’s Mars Express orbiter are offering a clearer view of Mars’ past. Scientists are interpreting these features as evidence of a long-ago Martian Ice Age that carved deep grooves, scratches, and craters into the Red Planet’s terrain. The findings shed light on…

ESA’s Mars Watch Captures Interstellar Visitor 3I/ATLAS in Glimpse of the Unknown
Rare Interstellar Visitor Reaches the Mars Scene On October 3, a rare interstellar visitor, comet 3I/ATLAS, passed by Mars at a distance of about 30 million kilometers. While comets are common in our solar neighborhood, 3I/ATLAS is extraordinary because it originated outside the Sun’s gravity, offering a priceless glimpse into material from another star system.…

Interstellar Visitor Lights Up Mars Sky: First Close Look by ESA Orbiters
Rare Interstellar Visitor Captured by Mars Orbiters In a landmark moment for planetary science and astronomy, an interstellar comet—3I/ATLAS—passed close to Mars on October 3, offering a rare glimpse from Earth’s neighboring planet. The event marked only the third time humanity has observed a true interstellar object, following 1I/ʻOumuamua (2017) and 2I/Borisov (2019). As the…

Interstellar Visitor 3I/ATLAS Skims Mars Sky: What ESA’s Rovers Revealed
Interstellar visitor crosses the Martian sky As October 2025 unfolded, astronomers faced a familiar puzzle: how do you observe something that’s on the opposite side of the Sun? The answer, in part, lay with the many rovers and spacecraft stationed on Mars. From 1 to 7 October, Europe’s ExoMars Trace Gas Orbiter (TGO) and Mars…

Mars rovers glimpse interstellar comet 3I/ATLAS near Mars
Rising Challenge: Observing a Visitor from Another Star In October 2025, astronomers faced a familiar problem with an unfamiliar guest. Comet 3I/ATLAS, a rare interstellar visitor entering our Solar System, was about to be swallowed by solar glare as it approached the Sun. From Earth, the glare of the Sun would wash out any view.…

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…
