The composite picture shows an SWS and an LWS spectrum overlaid on an ISOCAM image of the dark star-forming cloud Rho Ophiuchi. In the high-resolution SWS spectrum the main water feature is the strong emission at wavelengths around 38 microns. The LWS spectrum shows a large number of strong water-vapour emissions at wavelengths from 122 to 183 microns. Click here for the full image.
