Unprecedented Discovery: Ancient Galaxies Reveal Unparalleled Molecular Collection

Astronomers using the NOEMA radio telescope in France have discovered a record-breaking collection of 13 different molecules in two extremely ancient galaxies, APM 08279+5255 and NCv1.143, which are over 12 billion light-years away. The galaxies are forming stars at a rapid rate, and the detected molecules provide insights into the environments in which they are found. The discovery suggests a "top-heavy initial mass function," indicating that more massive stars were able to form in the early universe. This finding may explain the higher luminosity of galaxies in the early universe and the accelerated development of chemistry through supernova explosions.
