NGC 7814 is a spiral galaxy located in the constellation Pegasus. It is viewed from Earth nearly edge-on, allowing a distinct observation of its prominent dust lane and central bulge. The galaxy lies at an approximate distance of 40 million light-years from Earth.

Morphological Classification and Structure

Classified morphologically as SA(S)ab, NGC 7814 exhibits a tightly wound spiral structure with a central bulge and a thin disk. The galaxy is sometimes informally referred to as the "Little Sombrero" due to its visual similarity, in terms of structure and orientation, to the larger and better-known Sombrero Galaxy (Messier 104). This resemblance arises primarily from its dust lane bisecting a luminous central region, a configuration made more apparent by its edge-on alignment.

Dust and Stellar Content

High-resolution imagery of NGC 7814, including those taken by the Hubble Space Telescope, reveals the sharply defined dust structures embedded within its disk. These features are silhouetted against the galaxy's bright central bulge. The dust lane contains interstellar gas and dust that are associated with regions of star formation and the general interstellar medium typical of spiral galaxies.

The central bulge of NGC 7814 is densely populated with older, evolved stars. Due to the edge-on perspective, direct observation of spiral arms and star-forming regions is limited; however, the galaxy's flattened disk indicates the presence of spiral structures.

Observational Data and Significance

NGC 7814 has been a subject of multiple observational campaigns. It has been imaged in various wavelengths, including optical and near-infrared, which help characterize its stellar population and dust content. The galaxy’s symmetry and relatively thin disk combined with a prominent central bulge provide a useful case for studying the vertical structure of spiral galaxies.
