This image provided by the European Southern Observatory shows the complex distribution of molecular gas in the Central Molecular Zone (CMZ) of the Milky Way, designated in different colors: sulphur monoxide (cyan), silicon monoxide (green), isocyanic acid (red), cyanoacetylene (blue), and carbon monosulphide (magenta). The stars in the foreground of this image were observed at infrared wavelengths (Y, Z and J filters).
