Phosphorus exists in our DNA and is one of the basic elements that make up life  But how it reached Earth in its early days remains a mystery  Recently, scientists have tracked the journey of phosphorus-containing molecules from the universe to Earth by observing  regions where stars form  The observations show that phosphorus-containing molecules are produced during the formation of massive stars, and the newly formed stars release airflow, creating a channel in the interstellar cloud, and as the stars vibrate and release radiation, phosphorus-containing molecules deposit on the walls of these channels and produce a large number of phosphorus monoxide particles, which converge and merge one by one, turning from a small stone into a comet
And these comets became the messengers of life, carrying the molecules of life to Earth
Scientists have found evidence in meteorites, and studies have found that a few meteorites carry organic matter that contains phosphorus-containing molecules such as phosphorus monoxide.
