The colors of the different regions of NGC 1232 stand out in this picture—the central areas contain older reddish stars while the spiral arms are populated by younger blue stars and many star-forming regions. This galaxy is about 100 million light-years away and about twice the size of our Milky Way galaxy. Note the companion galaxy at the lower left, shaped like the squashed greek letter “theta”. NGC 1232A, the satellite galaxy of NGC 1232, is thought to be the cause of unusual bending in the spiral arms in its larger neighbor.
