The team also measured more than 70 chemical fingerprints in the gas, such as silicon monoxide, methanol, and acetone. Each responds to different physical conditions, so by comparing them, researchers can assess density, temperature, and motion, and identify where shocks ripple through clouds or where young stars add energy.，推荐阅读wps下载获取更多信息
