About this Image

Where does global star formation end in spiral galaxies? The above multi-wavelength image of NGC3596 combines H alpha emission (red), visible light in the R-band (white), and HI 21cm gas emission (blue). The H alpha and R-band data were obtained with the CFHT 3.6m, while the HI data were obtained with the Very Large Array. Each wavelength probes a different aspect of the galaxy; the H alpha emission traces recent star formation, the visible light traces past star formation, which is now seen as the old stellar disk, and the HI emission indicates where there is fuel for creating new stars.

    Technical Caption Narrowband H alpha emission and continuum, R-band, and HI 21 cm line emission are combined in the above RGB image to show star formation, the stellar disk, and HI. The H alpha and R-band data were obtained with the CFHT 3.6m. The images represent a total integration time of 6300 seconds for the OFF- band, 7200 seconds for the ON-band, and 810 seconds for the R-band exposures. The seeing for each exposure is about 0.95, 0.91, and 0.74 arcseconds respectively. The HI data were obtained with the VLA in Cs configuration, 361 minutes on source, with a beam size of 19.4x18.6 arcseconds.
