NGC 3184

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.

Equipment

L R G B color production was used to create this image.

Luminance = 75 minutes binned 1x1
Red = 20 minutes binned 2x2
Green = 20 minutes binned 2x2
Blue = 20 minutes binned 2x2

  • One iteration of L-R deconvolution (sharpening) algorithm using CCDsharp was applied to the luminance image.

  • The top image is the most recent data- and the equipment and exposure data refer to it.
