It’s well known that Earth’s atmosphere is composed of many different gases and particles, but a new study has revealed that it also contains a surprising ingredient: salt. The research, published in the journal Nature Communications, shows that salt from meteorites is quickly absorbed by Earth’s atmosphere, providing new insights into our planet’s climate and its evolution over billions of years.

According to the study, meteorites contain significant amounts of sodium chloride, which is quickly absorbed into Earth’s atmosphere. Once in the atmosphere, the salt is spread around the globe by winds, eventually making its way into the oceans. This process has been occurring since the formation of Earth 4.6 billion years ago, and is still ongoing today. The research suggests that the salt from meteorites has played a major role in maintaining Earth’s atmosphere and climate over the past few billion years.
