A stunning face-on spiral galaxy, Messier 74 was discovered in 1780 by Charles Messier’s observing assistant, the French astronomer Pierre Méchain. M74 is located roughly 32 million light-years away from Earth in the constellation Pisces. With an apparent magnitude of only 10, this galaxy appears as a very faint patch of light through small telescopes. M74 is a perfect example of a grand-design spiral galaxy. Symmetrical spiral arms reach out from the galaxy’s central nucleus and are traced by winding dust lanes. The arms are dotted with clusters of young, blue stars. This image is an integration of 16 hours of exposure time over 3 consecutive clear nights from our deck in Bortle 7, La Jolla, CA.
