Comets May Have Delivered Life-Sustaining Water to Earth

A new study reanalyzing data from the European Space Agency's Rosetta mission suggests that comets, particularly Jupiter-family comets like Comet 67P, may have played a significant role in delivering water to Earth. The study found that the deuterium-to-hydrogen (D/H) ratio of Comet 67P is closer to Earth's than previously thought, indicating that comets could have been major contributors to Earth's water supply. This challenges earlier beliefs that comets were unlikely sources of Earth's water.

Study Suggests Comets Brought Water to Earth and Other Planets

A new study suggests that comets may have delivered water to Earth, despite previous doubts raised by the 2014 Rosetta mission's findings. The mission found high deuterium levels in comet 67P, conflicting with Earth's water signature. Researchers now propose that cometary dust may have skewed these measurements, as deuterium-rich water adheres to dust grains, potentially altering observed ratios. This insight supports the theory that Jupiter-family comets contributed to Earth's water supply.
