Credit: Charles Kerton/Iowa State University Astronomers from the United States and South Korea have made the first high-resolution, radio telescope observations of the molecular clouds within a massive star-forming region of the outer Milky Way. Kerton said the astronomers used a newly commissioned radio telescope at the Taeduk Radio Astronomy Observatory in South Korea to take high resolution, carbon monoxide observations of the galactic region’s molecular clouds. They report the star formation efficiency of the entire CTB 102 region is about 5% to 10%, similar to other giant molecular clouds within the galaxy. But, they found one subregion of the clouds with a star formation efficiency of 17% to 37% (depending on how the mass of the subregion is calculated). They speculate the subregion is the site of a massive cluster of young, developing stars embedded in the molecular cloud.
