Centaurus A galaxy in IR (up) and UV (middle)
IR and UV images combinated: IR = red, UV = blue (down)
Center of the
galaxy is reddish so they emit more in infrared than in ultraviolet.
Exposure time of the UV image is longer because the earths atmosphere
is more transparent in IR than in UV. Also the camera is more
sensitive to IR than to UV.
