Embargoed to 0001 Thursday April 05 Undated handout enhanced image issued by the University of Cardiff of the Crab Nebula, a supernova explosion 6,500 light years from Earth. Earth-type life may be more rare and precious than is commonly thought, according to a UK study that hints at a cosmic lack of phosphorus. PRESS ASSOCIATION Photo. Issue date: Thursday April 5, 2018. The element is vital to energy storage and transfer in cells, and is part of the chemical backbone of DNA. Phosphorus is created in supernovae, exploding massive stars at the end of their lives. But the new research suggests that typical supernovae may not provide the conditions needed for forging the element. See PA story SCIENCE Phosphorus.
