This image was obtained with the Near Infrared Camera and Multi-Object Spectrograph (NICMOS)
onboard the NASA/ESA Hubble Space Telescope. It shows the region around the core of the barred
spiral galaxy NGC 2903. Several bright star clusters (white knots) are seen as well as the circumnuclear
ring around the core. The reddish areas are regions of ionised hydrogen and regions where large amounts
of dust partly obscure our view.
The image was constructed from two infrared NICMOS exposures: 704 seconds through an 1870 nm
filter (shown as red) and 192 seconds through a 1600 nm filter (shown as blue). The green colour in the
image is a combination of these two exposures.
