All-Sky Map of Infrared Sources by AKIRA


This AKARI view of the sky shows infrared sources at 9 micrometers in blue, at 18 micrometers in green, and at 90 micrometers in red. The image is arranged with the Galactic Center in the middle, and the plane of the Galaxy running horizontally across the map. Emission from the photospheres of stars dominates the 9 micrometers catalog, where the galactic disc and nuclear bulge are clearly visible, whereas dust and star formation in the disc of our Galaxy become are more prominent at 90 micrometers. Away from the Galactic Plane, many extragalactic objects are detected, tracing galaxy evolution and star formation in the distant Universe.
