Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home/yivumoo/public_html/show_object.php on line 167

History and Accurate Positions for the NGC/IC Objects (Corwin 2004)

NGC 7253 is an interacting double system with a bridge between the galaxies, plumes streaming off both, and lots of dust. In the blue, the brightest parts of the galaxies are knots in the disrupted arms. The images smooth over quite a bit in the red, but in the near-infrared, the two galaxies appear almost normal -- thin bulges evenly rising to bright nuclei. It is these bright nuclei that I have preserved as the positions for the two objects, with one of the bright knots in the southeastern object as an optical highlight.
