A mysterious celestial visitor is forcing scientists to rethink everything they thought they knew about comets.
The interstellar object 3I/ATLAS has delivered a wave of contradictory data since its discovery. Some suggest it is a primitive, volatile-rich comet, while others argue it behaves in ways that defy standard cometary physics. The result is a bitter divide among astronomers whose interpretations could reshape our understanding of how bodies from other star systems behave when they enter our Solar System.
