Explanation: Distorted [8] galaxy NGC 2442 can be found in the southern
constellation of the flying fish [9] , (Piscis) Volans [10] . Located about 50
million light-years away, the galaxy's two spiral arms extending from a
pronounced central bar have a hook-like appearance in wide-field images [11] .
But this mosaicked close-up [12] , constructed from Hubble Space Telescope and
European Southern Observatory data, follows the galaxy's structure in amazing
detail. Obscuring dust lanes, young blue star clusters and reddish star
forming [13]  regions surround a core of yellowish light from an older
population of stars. The sharp image data also reveal more distant background
galaxies seen right through NGC 2442's star clusters and nebulae. The image
spans about 75,000 light-years at the estimated distance of NGC 2442 [14] .

                  Tomorrow's picture: birds of a feather [15]
