A long, narrow slit isolates a small strip of sky. On this image, the slit is vertical. The spectrograph then splits the light from the slit into its individual colours, each point of the slit forming a horizontal rainbow. In this spectrum, the light from a distant galaxy appears as a faint horizontal line, peppered with bright dots corresponding to the colours emitted by the gas in the galaxy.
