Gas in Galaxies (image) Kavli Institute for the Physics and Mathematics of the Universe Share Print E-Mail Caption UV light associated with the gas is faint, but brighter in the infrared due to the presence of dust that impacts the UV more than the IR. Left: Map of the galaxy PACS-867 taken by ALMA where carbon monoxide (CO) emission shows molecular gas reservoir out of which stars form. Center: Image taken by Hubble Space Telescope Advanced Camera for Surveys of PACS-867 showing rest-frame UV light from young stars in individual components of highly disturbed galaxies as a result of a massive merger. Location of molecular gas in Left image is overlaid (blue contours), showing where new stars are forming. Right: Spitzer Space Telescope infrared image (3.6 micron) of PACS-867 highlights stars embedded in dust and associated with molecular gas. Credit Left image credit: ALMA (ESO/NAOJ/NRAO), J.
