The Carina nebula has been observed in a 120-300 µm band with a 100 cm balloon-borne telescope, and maps have been generated with a spatial resolution of ~1'. More than thirty compact sources were detected in the ~0.5 deg2 area scanned; many of these sources do not have IRAS PSC Point source Catalog counterparts. The diffuse emission accounts for nearly half of the total emission in the band. A comparison with observations at other wavelengths shows that the far-infrared emission is well correlated with other tracers of matter. The region appears to be rich in massive stars and most of the compact far-infrared sources are likely to be dust-gas clumps heated externally by these stars.
