This is NGC 4388, as seen by the NASA/ESA Hubble Space Telescope, one member of a massive and gravitationally-bound collection of over 1300 galaxies called the Virgo Cluster. The galaxy’s outskirts appear smooth and featureless, a classic feature of an elliptical galaxy, but its centre displays remarkable dust lanes within two symmetric spiral arms, emerging from the galaxy’s glowing core — one of the features of a spiral galaxy.
