Scientific paper

The Carina nebula has been observed in a 120 to 300 micron wavelength with a 100 cm balloon-borne telescope, and maps have been generated with a spatial resolution of about one minute of arc. More than thirty compact sources were detected in the approx 0.5 °2 area scanned; many of these sources do not have IRAS 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.
