NGC 7331 is the brightest galaxy in the field of a visual grouping known as the NGC 7331 Group of galaxies. In fact, the other members of the group, NGC 7335 , NGC 7336 , NGC 7337 and NGC 7340 , lie far in the background at distances of approximately 300–350 million light years.

2023年10月28日 · NGC 7331 (Caldwell 30) is an unbarred spiral galaxy located 39.8 million light-years away in the constellation Pegasus. With an apparent magnitude of 10.4, it can be seen in small telescopes. It is the brightest galaxy in the NGC 7331 Group.

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] It contains four other members, affectionately referred to as the "fleas": the lenticular or unbarred spirals NGC 7335 and NGC 7336, the barred spiral galaxy NGC 7337 and the …

2018年2月2日 · This NASA/ESA Hubble Space Telescope image shows a spiral galaxy known as NGC 7331. First spotted by the prolific galaxy hunter William Herschel in 1784, NGC 7331 is located about 45 million light-years away in the constellation of Pegasus (the Winged Horse).

2022年3月21日 · From a dark observing site, most observers can spot NGC 7331 through 50mm or larger binoculars. An 11-inch telescope and a magnification of 200x will reveal a bright core surrounded by a soft...

2022年10月5日 · NGC 7331 is a superb spiral galaxy lying in northern Pegasus, one of the brightest visible in the autumn sky, which can be found in apertures as small as 60–80mm (~three inches). It is a fine sight through a moderate-aperture telescope, looking like a miniature version of mighty Messier 31 in Andromeda, and makes an irresistible imaging ...

Galaxy NGC 7331. This galaxy was discovered by William Herschel on 5 September 1785 using his 18.7 inch reflector. He cataloged it as I 53 and noted: «Very bright, considerably large, much extended, much brighter in the middle, resolvable.» Given distances for NGC 7331 range from 12.8 Mpc to 16.2 Mpc (41 to 53 million light years).

Located about 4.5° northwest of Eta Pegasi, near the border of Lacerta, NGC 7331 was discovered in 1784 by William Herschel, and was one of the brightest galaxies overlooked by Messier in his catalog. It appears nearly edge on, tilted at an inclination of 77°.

2014年3月1日 · About 50 million light-years distant in the northern constellation Pegasus, NGC 7331 was recognized early on as a spiral nebula and is actually one of the brighter galaxies not included in Charles Messier's famous 18th century catalog.

Situated approximately 40 million light-years away, NGC 7331 is a large and luminous spiral galaxy with a well-defined central bulge, spiral arms, and a discernible galactic disk. NGC 7331’s spiral arms are interspersed with patches of dark dust …
