Why Don't Comets Ever Have a Green Tail?

Comets have fascinated humans for centuries due to their vibrant colors. Scientists have long wondered why comet heads are green but not their tails. Recent research reveals that the green color is due to dicarbon, a molecule formed and destroyed by UV light. This instability prevents the green color from reaching the tail. Experiments simulating space conditions confirmed this theory, solving a century-old mystery. Understanding these processes highlights the importance of scientific validation and encourages future research.
