NGC 672 and IC 1727


This picturesque duo of interacting galaxies is in the constellation Triangulum and is located 24 million light-years from us. A third one, standing vertically, is 540 million light-years away. Many more fainter ones can be seen and are obviously much farter away. The pinkish ares in the main galaxies are HII (ionized hydrogen) areas indicating recent birth of stars.
