NGC 7722 is a lenticular galaxy located about 187 million light-years away in the constellation Pegasus. A lenticular, meaning “lens-shaped,” galaxy is a type whose classification sits between more familiar spiral galaxies and elliptical galaxies. In this case, NGC 7722 lacks the defined arms of a spiral galaxy, while it has an extended, glowing halo and a bright bulge in its center like an elliptical galaxy. Unlike elliptical galaxies, it has a visible disk — concentric rings swirl around its bright nucleus. This NASA/ESA Hubble Space Telescope image of NGC 7722, a lenticular galaxy located about 187 million light-years away, features concentric rings of dust and gas that appear to swirl around its bright nucleus.
