NGC 6334 has been mapped with a 40--250 ..mu..m photometer with 1' resolution. Six sources of far-infrared radiation have been detected. The second-strongest source was not detected in an earlier variable far-infrared source. The new source, located at the position of OH and H/sub 2/O maser sources, is extended (0'.7 FEHM) and has a bolometric luminosity of 1.9 x 10/sup 5/ L/sub sun/ and many represent a hitherto unobserved transient stage of protostellar collapse.
