Professor KOO BonChul Discovers Phosphorous From Space

Professor KOO BonChul of the Department of Physics and Astronomy discovered a substantial amount of phosphorous out in space, an element which is a component of DNA and human bones. This proves that the major 6 elements needed to preserve life -- carbon, hydrogen, nitrogen, oxygen, phosphorous and sulfur -- all originate from the universe. The SNU, Toronto University and Harvard-Smithsonian Center for Astrophysics joint research team succeeded in observing infrared rays emitted by phosphorous at the Cassiopeia A spot. The observed amount of phosphorous this time is 100 times stronger than what is usually observed. The research team believes this phosphorous was created some 300 years ago when a star, 15 to 25 times larger than the sun, exploded. The specifics of this discovery were published in the December 12 publication of Science.
