This NASA/ESA Hubble Space Telescope image shows NGC 7722, a lenticular galaxy about 187 million light-years away in the constellation Pegasus. This “lens-shaped” galaxy sits in between more familiar spiral alaxies and elliptical galaxies in the galaxy classification scheme. The dark, dramatic dust lanes are the fingerprints of an ancient galaxy merger. from Universe Today https://ift.tt/uRvGInj via IFTTT
