A previously 'vanished' interstellar comet has stunned astronomers worldwide by reappearing with a longer, brighter, and more structured tail, reigniting curiosity about the mysterious object's composition and behaviour.
Just weeks after its tail seemed to disappear entirely, 3I/ATLAS, the third confirmed interstellar object, has revealed a strikingly luminous ion tail and complex dust structures. Captured in a composite image on 10 November 2025, these observations were made under challenging conditions, with the comet just 14 degrees above the horizon and a 61 per cent illuminated Moon interfering. Yet the images show remarkable clarity and detail. Researchers and amateur astronomers alike are scrambling to understand the mechanisms driving this dramatic transformation.
