Phosphorus is one of the important elements needed for life on Earth, and it is rare in the universe. But in a recently published study, astronomers have discovered a new class of phosphorous stars, meaning extraterrestrial life may be more common than previously thought. The six elements often talked about in biology include carbon, hydrogen, nitrogen, oxygen, sulfur, and phosphorus.

Phosphorus is not only known to be an important structural element of both DNA and RNA, but also helps to transfer energy through cells and regulate other critical physiological processes.
For a long time, scientists have believed that phosphorus comes mainly from the eruptions of new and supernovae, meaning that life in the universe may be much less than we expected.
If so, how did the earth become the lucky one who could give birth to life? One guess is that our solar system happens to be around such a supernova.
But a new study from the Canaria Stakes (IAC) and la Clunya University suggests that this is more common than we think.
The team examined survey data from the Sloan Digital Survey Project and analyzed infrared light signals from a series of stars and found 15 phosphorous-rich stars.
These stars make up a class of never-before-discovered objects, and usually have higher elements such as magnesium, silicon, oxygen, aluminum, and vanadium, which astronomers find puzzling.
Lead researcher Thomas Masseron said the team could not understand phosphorus-rich stars based on current understanding of stellar evolution and elementsynthesis. These results suggest that they not only encounter a new type of celestial body, but also deeply explore the physical mechanismof the inner reaction of the star.
Details of the study have been published in the recently published journal Nature Communications under the headline “The Sherme-rich stars with the stush shofs s- and sleats the syllaly sleat sydd sydd.”
