The mysterious case of the missing noble gas. Nature News The theories presented was pretty interesting, as some chemicals may exhibits some strange chemical properties in the environment with high temperature and pressure, xenon may be able to dissolve in other compounds in these extreme environment.

As part of its mission, Rosetta circled the comet to find out about the isotopic signature of the xenon trapped in the ice, uncovering possible clues about where Earth's atmospheric xenon had come from.
After analysing the spectrometry data collected by the spacecraft, Marty and his team discovered that the xenon in the comet's ice had been there before the birth of the Solar System.
Additionally, the weird isotopic signature of the comet's xenon matched the xenon in Earth's atmosphere which had been derived from an unknown source. The team explored other possible explanations for how this exotic type of xenon came to be on Earth. But the results revealed that the isotopic signature of the comet's xenon differed from the typical signature found in Solar System xenon, indicating that it was primordial in origin.
Ruling out these other explanations, Marty is confident that some of Earth's xenon was brought here by comets. With one answer for the origin of our planet's xenon uncovered, it leads to broader questions of what else comets may have brought down to Earth in our planet's early days. The research has been published in Science.
