3I/ATLAS Update: Strange Tail, CO₂, and Nickel Defy Science
1943I/ATLAS Update: New Data Reveals Unexpected Properties
The interstellar object 3I/ATLAS is breaking the rules of comet science. Discovered in July 2025, this interstellar comet is nearly 50 kilometers wide and already shows behavior unlike anything we’ve seen before.
Recent telescope data reveal a 56,000 km tail pointing toward the Sun, not away. Even stranger, the James Webb Space Telescope and Gemini South detected a carbon dioxide to water ratio of 8:1, along with nickel emission lines but no iron — findings never observed in any comet. These anomalies fuel new questions about whether 3I/ATLAS is a comet or something else entirely.
At an estimated 46 km across, 3I/ATLAS dwarfs the last interstellar visitor, 2I/Borisov. Its retrograde orbit along the ecliptic plane has odds of less than 1 in 500, making this a one-in-a-lifetime event. As it nears its October 29th perihelion, scientists like Avi Loeb are closely watching for answers to what this object really is.
