Astronomers are tracking an extraordinary visitor to our solar system — the interstellar comet 3I/ATLAS — which is becoming brighter and showing distinct shifts in its appearance as it nears its closest approach to Earth on December 19, 2025. New observations show that the comet’s coma and tail are intensifying and that its color is evolving, offering scientists a rare chance to study material from another star system.
