Located in Sextans (practically a self-referential constellation since
you basically need a Sextant to find the stars...) NGC 3169 (to the upper
right) and NGC 3166 (in the lower left) make a very pretty pair of galaxies.
They are truly near to one another and affect each other's structure. Most
notably it appears that NGC 3166 has quieted down in terms of star
formation; while NGC 3169 continues to produce new stars as indicated by
the bluish spiral arms and pink star forming regions.
NGC 3169 and 3166 are separated by a mere 50,000 light years (half the
diameter of our own galaxy). These galaxies
dance some 60 million light years in the distance.
