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.“This region is behind a nearby cloud of dust and gas,” said Charles Kerton, an associate professor of physics and astronomy at Iowa State University and a member of the study team. “The cloud blocks the light and so we have to use infrared or radio observations to study it.”The Milky Way region is called CTB 102. It’s about 14,000 light years from Earth. It’s classified as an HII region, meaning it contains clouds of ionized – charged – hydrogen atoms. And, because of its distance from Earth and the dust and gas in between, it has been difficult to study.And so, “this region has been very poorly mapped out,” Kerton said.The astronomers describe their first draft of a new, higher-resolution map for the region in a paper recently accepted for publication in the Astrophysical Journal. Lead authors are Sung-ju Kang, a staff scientist at the Korea Astronomy and Space Science Institute and a former graduate student at Iowa State University; and Brandon Marshall, a former Iowa State graduate student who ...
