NGC 7332 is an edge-on peculiar lenticular galaxy [1] [3] located about 67 million light-years away. [2] It possesses a (peanut shell)-shaped bulge, associated with stellar bar. [5] It was discovered on September 19, 1784 by the astronomer William Herschel. [6]

NGC 7332 and NGC 7339 form a dynamically isolated binary system (number 570 in the catalog of double galaxies compiled by Igor Karachentsev), [3] and are likely orbiting each other. [3] NGC 7332 is the brighter of the two galaxies. [3]

In the sky NGC 7339 lies 5' away from NGC 7332. [7] NGC 7332 is an unusually blue object with a corrected apparent B-magnitude of 11.5. [7] A 130mm to 200mm telescope will be needed to visually detect this pair of galaxies. [8] The two galaxies will appear at almost a right angle to one another.

NGC 3628 Spiral galaxy in the constellation Leo

NGC 3628, also known as the Hamburger Galaxy or Sarah's Galaxy, is an unbarred spiral galaxy about 35 million light-years away in the constellation Leo. It was discovered by William Herschel in 1784. It has an approximately 300,000 light-years long tidal tail. Along with M65 and M66, NGC 3628 forms the Leo Triplet, a small group of galaxies. Its most conspicuous feature is the broad and obscuring band of dust located along the outer edge of its spiral arms, effectively transecting the galaxy to the view from Earth.

<i>Atlas of Peculiar Galaxies</i> Catalogue of peculiar galaxies produced by Halton Arp

The Atlas of Peculiar Galaxies is a catalog of peculiar galaxies produced by Halton Arp in 1966. A total of 338 galaxies are presented in the atlas, which was originally published in 1966 by the California Institute of Technology. The primary goal of the catalog was to present photographs of examples of the different kinds of peculiar structures found among galaxies.
