The Molecular and Atomic Gas in IC 342

Minimum credit line: Image courtesy of NRAO/AUI (for details, see Image Use Policy).

About this Image

An optical image of the nearby barred spiral galaxy IC 342 (shown in blueish-white) with overlays in red to show the location of its atomic hydrogen, and in green to show the location of its cool molecular gas (traced by emission from the carbon monoxide molecule). The gas in this galaxy is predominantly atomic at large radii and predominantly molecular in the inner regions.

Investigator(s):  L. P. Crosthwaite, J. L. Turner
