Blue Mountain Vista Observatory New RInggold PA
Messier 74 (also known as NGC 628) is a face-on spiral galaxy in the constellation Pisces. It is about
32 million light-years away from Earth. The galaxy contains two clearly defined spiral arms. The
galaxy's low surface brightness makes it a somewhat difficult Messier object for amateur
astronomers to observe. It is estimated that M74 is home to about 100 billion stars. M74 is the
brightest member of the M74 Group, a group of 5-7 galaxies that also includes the peculiar spiral
galaxy NGC 660 and a few irregular galaxies.
