Pegasus is a constellation in the northern sky, named after the winged horse Pegasus in Greek mythology. It was one of the 48 constellations listed by the 2nd-century astronomer Ptolemy , and is one of the 88 constellations recognised today.
NGC 7331 Group is a visual grouping of galaxies in the constellation Pegasus. Spiral galaxy NGC 7331 is a foreground galaxy in the same field as the collection, which is also called the Deer Lick Group. [1]
Stephan's Quintet is a visual grouping of five galaxies of which four form the first compact galaxy group ever discovered. [2] The group, visible in the constellation Pegasus, was discovered by Édouard Stephan in 1877 at the Marseille Observatory. [3]
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]
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 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 7741 is a barred spiral galaxy located in the constellation Pegasus. It is located at a distance of circa 40 million light years from Earth, which, given its apparent dimensions, means that NGC 7741 is about 50,000 light years across. It was discovered by William Herschel on September 10, 1784. [2] NGC 7741 has a strong bar and two spiral arms.
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 ...
