An article published in “The Astrophysical Journal” describes the observations of the birthplaces of most of today’s stars. A team of astronomers led by Wiphu Rujopakam of the University of Tokyo and the Chulalongkorn University in Bangkok used the VLA and ALMA radio telescopes to study galaxies so far away that we see them as they were about 10 billion years ago, when in the universe there was a peak period of star formation.
