Description Recent studies have found that the star formation rate in local Galactic star forming regions is proportional to the amount of dense gas present in the respective regions, once a minimum extinction threshold is surpassed. However, based on the fact that local Galactic star formation represents a relatively small sample of star formation in our own Galaxy and due to the inherent difficulties in obtaining measurements of a larger volume of the Galaxy, the best way to confirm and improve on this result is to observe the star formation rates and the corresponding amounts of dense material over an entire external galaxy. While systematic millimeter-line observations of dense molecular material in an external Galaxy will have to await ALMA, we have started a project to already obtain detailed studies of the infrared luminosities and star formation rates of individual resolved star forming regions in the nearby spiral galaxy NGC 300, using Spitzer, GALEX, APEX, SMA, and ground-based Halpha data. NGC 300 is the most nearby spiral galaxy at southern declinations and thus an ideal ALMA target. We are currently in the process of obtaining total molecular masses of the HII regions in this galaxy from APEX CO observations while constraining the star formation rates with Spitzer, GALEX,and Halpha data. Here we propose to obtain unbiased mapping of the entire galaxy in both the PACS and the SPIRE far-infrared and submillimeter bands. This will provide a) an unbiased way to find and identify giant molecular clouds in this galaxy and obtain their masses, b) much better spectral energy distributions of the HII and other star forming regions and c) improved star formation rates for these regions.

Mission Description Herschel was launched on 14 May 2009! It is the fourth 'cornerstone' mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities.
