Researchers have found that the water on Comet 67P/Churyumov–Gerasimenko has a molecular signature similar to Earth’s ocean water, challenging recent conclusions. This connection, identified by the ratio of deuterium (D) to regular hydrogen (H) in the water, suggests that Jupiter-family comets like 67P may have contributed to delivering water to Earth.
