Cutting-edge research challenges previous understanding of Earth's water origin by questioning the role of comets in delivering water. New findings highlight the importance of specific molecular signatures, particularly ratios of deuterium isotopes, in understanding where Earth's water came from.

For the last few decades, deuterium levels in water found in the vapor trails of several Jupiter-family comets displayed similar levels to that of Earth's water.
When comets pass closer to the sun during their orbit, their surfaces warm up, which can release gas and dust from the comet's surface. Water with deuterium sticks to dust grains more readily than regular water does, and when ice clinging to the dust grains is released into the vapor trail of a comet, it could give observers the impression that the water in the comet is more deuterium-rich than it actually is.
