NGC 672 and IC 1727 - Interacting Pair in Triangulum 40x180sec at iso 1600 NGC 672 (top) and IC 1727 are quite the interesting couple. Being only 88,000 light years apart - about the diameter of one of them - they interact extensively, even to the degree that they are encapsulated in a common envelope of shared gas and intermingling stars. This pair is theorized by Zitrin and Brosch to be situated along the same dark-matter filament in an otherwise galaxy-sparse part of the universe. The theory is that the dark matter has focused the regular matter in the region, allowing it to condense into small, irregular galaxies and then into larger spirals by way of heirarchial clustering.
