中国天眼，又有新发现！
我国科学家日前利用“中国天眼”FAST揭示了银河系星际介质前所未见的高清细节，对研究银河系内的星际生态循环具有重要意义。
Using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST), or the "China Sky Eye," Chinese scientists revealed the unprecedented details of the Galactic interstellar medium.
Led by Han Jinlin, a scientist with the National Astronomical Observatories of China, the research team published their new findings Saturday in the latest journal Science China: Physics, Mechanics & Astronomy.
According to Han, during the sensitive survey for pulsars using the FAST, the spectral line data of the interstellar medium was recorded simultaneously. Though the fine calibration is still underway, the results available are already the most sensitive for detecting neutral hydrogen gas clouds to date, showing unprecedented details about the distribution of neutral hydrogen gas.
The research team has also revealed the luminous regions ionized by bright stars and the diffuse ionized gas of unknown origin.
"The sensitive FAST observations can reveal unprecedented details of the Milky Way," said Jing Yipeng, an academician with the Chinese Academy of Sciences and professor at Shanghai Jiao Tong University. "The databases of neutral hydrogen and ionized hydrogen published by these papers are valuable resources for astronomers over the world," Jing added.
