Here are other
optical and submillimeter pictures.
Star burst is
the dominant theme in the SHARC2 image in the middle.In addition, the SHARC2 image shows
the site of future action for starburst where it has abundant supply of cold
dust and gas.The image on the
right overlays SHARC2 contours on an HST image in optical wavelength.The sub-millimeter image complements
the optical images in revealing the actions deeply embedded in the dense
cores of dust and gas, not visible in the optical images.
