Optical image of Stephan’s Quintet galaxy group showing regions of abundant molecular gas

Caption

The contour lines show radio emissions from carbon monoxide molecules in Stephan’s Quintet, arranged like the contours on a topographic map. Just as higher contours on a map represent higher elevations, higher contour levels here represent stronger CO emission, indicating regions with more molecular gas.
