There’s the Spanish Dancer Galaxy, and then the baseball-like spiral galaxy ESO 420-G013 as captured by NASA / ESA’s Hubble. This is both a face-on spiral and Seyfert galaxy, complete with dark lanes of dust that are visible against the background glow of the galaxy’s many stars.
What are Seyfert galaxies? These are typically spiral galaxies with very bright nuclei, caused by supermassive black holes at their centers accreting material releaseing vast amounts of radiation. For ESO 420-G013, it has an almost perfectly round disk, brighter core, and whirled filaments of dark dust.

The cores of these ‘active galaxies’ are brightest when observing light outside the visible spectrum. Often galaxies with these kinds of active galactic nuclei are so bright that the host galaxy itself cannot be seen, washed out by the glow of its nuclei, but Seyfert galaxies are distinctive because the galaxy itself is also visible,” said the NASA Hubble Mission Team.
