Vast web of cold gas observed at the heart of the Milky Way

WASHINGTON: Astronomers have produced the largest and most detailed map ever made of the vast web of cold cosmic gas stretching across the heart of our galaxy, showing thread-like filaments resembling rivers of material flowing through space that sometimes converge into bright clouds where new stars form. Using the Chile-based ALMA telescope, the researchers examined the dynamics and chemistry of the Milky Way’s central region, a chaotic and energetic expanse that serves as an enormous reservoir of raw material for making stars. The region harbors dense clouds of gas and dust.
