Phosphorus is present in our DNA and is one of the building blocks of life, but how it got to Earth early on remains a mystery  Recently, scientists have tracked the journey of phosphorus-containing molecules from the universe to Earth by observing star-forming regions  The observations suggest that the phosphorus-containing molecules are created when massive stars form, and the newly formed stars release airflow that creates a channel in the interstellar cloud
As the star vibrated and released radiation, phosphorus-containing molecules deposited on the walls of these channels and produced a large number of phosphorus monoxide particles, which gradually converged and merged, turning from a small rock into a comet, and these comets became the Messenger of life and came to earth with life molecules
When the comet hits the earth's surface, it can generate 360,000 atmospheres of pressure and the temperature can reach 2500 ℃, which will cause unknown chemical changes in the phosphorus element in the comet crystal
