Key facts
- China's FAST telescope has mapped neutral hydrogen across a large area of the Milky Way.
- Neutral hydrogen is a key gas for the formation of stars.
- The observations provide insights into the distribution of this gas within the galaxy.
China's Five-hundred-meter Aperture Spherical Telescope (FAST) has successfully mapped neutral hydrogen across a significant portion of the Milky Way. Neutral hydrogen is a fundamental component of interstellar gas and a crucial ingredient for the formation of stars. The detailed mapping provides astronomers with valuable data to study galactic structure and the processes of star birth within our galaxy.
