NGC 7726 is a large barred spiral galaxy located in the constellation Pegasus in the northern sky. It is estimated to be 348 million light-years from the Milky Way and about 150,000 light-years in diameter. Many other objects are located within a close proximity to NGC 7726, including NGC 7720, NGC 7728, IC 5341 and IC 5342. [2] [1] [3]
NGC 7331, also known as Caldwell 30, is an unbarred spiral galaxy about 40 million light-years (12 Mpc) away in the constellation Pegasus. It was discovered by William Herschel on 6 September 1784. [4] The galaxy appears similar in size and structure to the Milky Way, and is sometimes referred to as "the Milky Way's twin". [5]
NGC 7769 is an unbarred spiral galaxy in the constellation of Pegasus. Its velocity with respect to the cosmic microwave background is 3855 ± 25 km/s, which corresponds to a Hubble distance of 56.85 ± 4 Mpc (∼185 million light-years). [1] It was discovered by German-British astronomer William Herschel on 18 September 1784. [2]
Epsilon Pegasi (Latinised from ε Pegasi, abbreviated Epsilon Peg, ε Peg), formally named Enif / ˈ iː n ɪ f /, is the brightest star in the northern constellation of Pegasus. With an average apparent visual magnitude of 2.4, [3] this is a second-magnitude star that is readily visible to the naked eye.
Messier 15 or M15 (also designated NGC 7078 and sometimes known as the Great Pegasus Cluster) is a globular cluster in the constellation Pegasus.It was discovered by Jean-Dominique Maraldi in 1746 and included in Charles Messier's catalogue of comet-like objects in 1764.
NGC 7777 is a lenticular galaxy [1] in the constellation of Pegasus. [2] It was discovered on 25 October 1876 by French astronomer Édouard Stephan. [3] See also.
NGC 7217 is a gas-poor system [2] whose main features are the presence of several rings of stars concentric to its nucleus: three main ones –the outermost one being of the most prominent and the one that features most of the gas and star formation of this galaxy – [2] plus several others inside the innermost one discovered with the help of the Hubble Space Telescope; a feature that ...
