The night side image of Venus taken by the Akatsuki's IR1 (InfraRed1 micrometer) camera on January 21, 2016 at 09:38 JST, and the Akatsuki's altitude was 38 000 km at that time. The image mainly shows the distribution of the thermal radiation from the Venusian surface, and the darker areas correspond to highlands of lower temperature. A highland called Aphrodite appears as the large low temperature region.
