Herschel's HIFI Follows The Trail Of Cosmic Water

This HIFI spectrum shows water lines toward low-mass protostars in the NGC 1333 star-forming region. IRAS-2A, -4A and -4B refer to different members of the NGC 1333 cluster. The spectrum is superimposed on a Spitzer image of the region.

Details of the study from which the spectrum is taken can be found in the paper of Kristensen et al., (in preparation) to appear in a special issue of Astronomy and Astrophysics dedicated to first scientific results from HIFI.
