M74

Messier 74 is a pretty spiral galaxy seen face-on 35 million light-years away in the constellation of Pisces.

The symmetrical structure of the whole galaxy was doubtless caused by a star-forming density wave which was at the origin of the spiral arms.

A very big telescope (at least 40 cm diameter) is needed to begin to see this spiral visually, although it can be seen as a small blurred spot using binoculars.
