Comet Research - Page 2

Comets’ heads can be green, but never their tails. After 90 years, we finally know why. A study has solved a 90-year-old mystery by proving the mechanism by which dicarbon -- the chemical that makes some comets' heads green -- is broken up by sunlight. This explains why the vibrant green color never reaches the comet's tail. Source 5h.
