Mysterious Dark Comets May Hold Clues to Earth's Origins

Scientists have discovered 14 'dark comets,' which resemble asteroids but behave like comets, revealing two distinct types based on their orbits and sizes. These findings suggest that dark comets may have played a role in delivering materials necessary for life on Earth. The discovery raises questions about their composition and potential impact on Earth, as their anomalous acceleration could affect orbital predictions. This research, published in the Proceedings of the National Academy of Sciences, highlights the need for further study to understand these enigmatic space objects.
