M74 is a loosely wound (type Sc) spiral galaxy in Pisces, found at a distance of 30 million light years (redshift 0.0022). It has many clusters of young stars and the associated nebulae, showing extensive regions of star formation. It was discovered by Pierre Méchain, a French astronomer, in 1780.
Alpha Piscium (α Piscium) is a binary star [6] system in the equatorial constellation of Pisces.Based upon parallax measurements made by the Hipparcos spacecraft, it is about 151 light-years from the Solar System.
Messier 74 (also known as NGC 628 and Phantom Galaxy) is a large spiral galaxy in the equatorial constellation Pisces. [ a ] It is about 32 million light-years away from Earth. [ 6 ] The galaxy contains two clearly defined spiral arms and is therefore used as an archetypal example of a grand design spiral galaxy . [ 7 ]

The edges of the superclusters and Laniakea were not clearly known at the time of Laniakea's definition. [6] Since then, the study of the edges of the supercluster and of structures beyond them has substantially improved. [15] [16] Laniakea is itself a constituent part of the Pisces–Cetus Supercluster Complex, a galaxy filament.
Sigma Piscium (Sigma Psc, σ Piscium, σ Psc) is a main-sequence star in the zodiac constellation of Pisces.It has an apparent magnitude of +5.50, meaning it is barely visible to the naked eye, according to the Bortle scale.
Star clusters are important in many areas of astronomy. The reason behind this is that almost all the stars in old clusters were born at roughly the same time. [15] Various properties of all the stars in a cluster are a function only of mass, and so stellar evolution theories rely on observations of open and globular clusters.
ζ Piscium (Latinised to Zeta Piscium) is the system's Bayer designation.The designations of the three constituents as Zeta Piscium A, B and C, and those of A's and B's components - Zeta Piscium Aa, Ab, Ba and Bb - derive from the convention used by the Washington Multiplicity Catalog (WMC) for multiple star systems, and adopted by the International Astronomical Union (IAU).
