| Abstract: | Near-infrared diffuse radiation at 1 μm – 5 μm was observed using cold optics on board a sounding rocket. The observed surface brightness is too bright to be explained by known diffuse sources and its significant part is possibly attributed to the cosmic origin. Extragalactic background radiation thus obtained is brighter than theoretically estimated so that new energy sources at an early epoch of the universe are required. |
