NGC 911
NGC 911 is an elliptical galaxy located approximately 145 million light-years away in the constellation Andromeda. It is a member of the NGC 1023 Group, a group of galaxies that also includes NGC 891 and NGC 1023.
NGC 911 is classified as an E0 galaxy, indicating that it is an elliptical galaxy with a nearly spherical shape. It exhibits a smooth, featureless structure, typical of elliptical galaxies. The galaxy's core is relatively bright and concentrated.
Elliptical galaxies like NGC 911 are generally composed of older stars and have little to no ongoing star formation. They are believed to form through mergers of smaller galaxies, a process that strips away gas and dust, halting the formation of new stars.
NGC 911 has been observed at various wavelengths, including optical, infrared, and radio. These observations have helped astronomers to study its stellar population, dust content, and other physical properties.
While NGC 911 appears relatively isolated in images, it is gravitationally bound to other galaxies in the NGC 1023 Group, influencing their dynamics and evolution.
