3I/ATLAS Goes From Green to Gold — What Changed in the Sky?
Observers tracking 3I/ATLAS have noticed a striking visual shift: the comet’s glow appears to be changing from a vivid green to a warmer yellow-gold hue . This kind of color change is not cosmetic. It usually signals a real physical transition in what the comet is releasing into space as it moves and heats up. The green color commonly seen in comets comes from carbon-based gases , especially diatomic carbon , that fluoresce under sunlight. When a comet is colder or farther out, these gases dominate the coma and give it that classic emerald glow . As the object warms and becomes more active, heavier material begins to escape. Dust reflects sunlight more evenly across the spectrum, producing a yellow or golden appearance. In simple terms, gas dominance gives way to dust dominance. From a Platform 1 Fringe perspective, this transition matters because it suggests 3I/ATLAS is evolving rapidly rather than behaving like a static ice ball. A dust-rich phase can indicate structural changes, s...
Beyond the Ice Wall of Antarctica
Antarctica stands as the southernmost and least-populated continent on Earth, predominantly situated below the Antarctic Circle and encompassed by the Southern Ocean, also known as the Antarctic Ocean. Home to the geographic South Pole, it holds the distinction of being the coldest, driest, and windiest of all continents, with the highest average elevation. Primarily a polar desert, it experiences minimal annual precipitation, exceeding 200 mm (8 in) along the coast but considerably less inland. The indigenous animal species include mites, nematodes, penguins, seals, and tardigrades. Vegetation, where present, primarily manifests as lichen or moss.
