||At a distance of 40 million light years away, NGC 3184 must be
the showcase of its neighborhood. This galaxy has striking blue spiral
arms with many pink star forming regions. I took an image of this galaxy
back in 1998 and there is supernova explosion
in the old picture (bottom image). Do you see the star in the old picture that
is not in the more recent images? Note that in the more recent images
that the position of the supernova is the same as a pink star forming region.
Most likely a massive star in this stellar nursery lived a short life and
blew up. Perhaps this will trigger even more star formation in this galaxy.
Also notice the improvement in image quality
between the four images.
