NGC 3166 & NGC 3169
60 million light-years
This pair of galaxies are in close proximity to one another in the constellation of Sextans (the sextant). They are affecting one another's structures through their gravitational influence. NGC 3169 (on the left) continues to engage in star formation as indicated by the blue hue, while NGC 3166 is not as active.
