NICMOS enables the Hubble telescope to see near-infrared wavelengths of light, so that it can penetrate the dust that obscures the inner hub of the galaxy. The ring-like structure seen by NICMOS encircles the core and is about 720 light-years wide, which is the typical size of most star-forming rings found in disc galaxies.

The human eye cannot see infrared light so colours have been assigned to correspond to near-infrared wavelengths. The blue light represents shorter near-infrared wavelengths and the red light corresponds to longer wavelengths.

NGC 4013, which looks similar to our Milky Way Galaxy, resides in the constellation Ursa Major, 55 million light-years from Earth.
