The infrared sources in the AKARI catalogue detected at 90 micrometers
The infrared sources in the AKARI catalogue detected at 90 micrometers are plotted on the sky map. About 64,000 sources are presented. The colour of the dots indicates the brightness of the sources; brighter from red to white. The stripe along the horizontal direction is the Milky Way. The centre of our Galaxy is at the centre of the image. Sources distributed far from the Milky Way are mostly galaxies with star formation activity.
