NGC 7157 is an early spiral galaxy in Piscis Austrinus
NGC 7157 (ESO 532-003) is an early spiral galaxy in the constellation Piscis Austrinus . It shines at magnitude 14.0 and spans 1.2′ × 33″. It is faint: a 10-inch or larger telescope, or a camera, and it is highest in the evening sky in October.
Galaxy: a system of billions of stars, gas and dust held together by gravity, far outside the Milky Way. Spiral galaxies have a disk with arms; elliptical galaxies are smooth, round or oval swarms of older stars.
