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
The early impact events of comets brought 10 trillion kilograms of organic matter to the earth every year, which opened the evolution of life on earth after they entered the earth's environment.
