Description: This spiral galaxy is part of the M 81 group. It has a small central nucleus and prominent HII regions (the pink areas in the above image). Although NGC 2403 is known as an 'effervescent' galaxy because it has a lot of active star formation, it was the site of a spectacular death of a star in 2004. This supernova was the closest and brightest in over a decade.
