NGC 6622 is an interacting spiral galaxy in the constellation Draco. [1] It is located around 313 million light-years away, and it was discovered by Edward D. Swift and Lewis A. Swift on June 2, 1885. [1] [2] NGC 6622 interacts with NGC 6621, with their closest approach having taken place about 100 million years before the moment seen now. [3] NGC 6622 and NGC 6621 are included in the Atlas of Peculiar Galaxies as Arp 81 in the category "spiral galaxies with large high surface brightness companions". [4] [5]

NGC 6622 is the smaller of the two, and is a very disturbed galaxy. [5] [1] The encounter has left NGC 6622 very deformed, as it was once a spiral galaxy. [6] [1] The collision has also triggered extensive star formation between the two galaxies. [7] The most intense star formation takes place in the region between the two nuclei, where a large population of luminous clusters, also known as super star clusters, has been observed. At this region is observed the most tidal stress. [6] [2] The brightest and bluest clusters are less than 100 million years old, [2] with the youngest being less than 10 million years old. [4] The side of the galaxy further from the companion features noticeably less star formation activity. [3] [1] [7]

NGC 4631 is a barred spiral galaxy in the constellation Canes Venatici about 30 million light years away from Earth. It was discovered on 20 March 1787 by German-British astronomer William Herschel. This galaxy's slightly distorted wedge shape gives it the appearance of a herring or a whale, hence its nickname. Because this nearby galaxy is seen edge-on from Earth, professional astronomers observe this galaxy to better understand the gas and stars located outside the plane of the galaxy.

NGC 6872, also known as the Condor Galaxy, is a large barred spiral galaxy of type SB(s)b pec in the constellation Pavo. It is 212 million light-years (65 Mpc) from Earth. NGC 6872 is interacting with the lenticular galaxy IC 4970, which is less than one twelfth as large. The galaxy has two elongated arms with a diameter based on ultraviolet light of over 522,000 light-years (160,000 pc), and a D25.5 isophotal diameter of over 717,000 light-years (220,000 pc), making it the largest known spiral galaxy. It was discovered on 27 June 1835 by English astronomer John Herschel.

<span class="mw-page-title-main">NGC 4911</span> Galaxy in the constellation Coma Berenices

NGC 4911 is a disturbed, warped spiral galaxy with a bright prominent central starburst ring and located deep within the Coma Cluster of galaxies, which lies some 300 million light years away in the northern constellation Coma Berenices. NGC 4911 is believed to be interacting with its warped, barred lenticular companion, producing the enhanced star formation and shell-like appearance seen in optical images. The galaxy contains rich lanes of dust and gas near its centre. The existence of clouds of hydrogen within the galaxy indicates ongoing star formation. It is rare for a spiral galaxy to be situated at the heart of a cluster.

NGC 428 is a barred spiral galaxy in the constellation of Cetus, with its spiral structure distorted and warped, possibly the result of the collision of two galaxies. There appears to be a substantial amount of star formation occurring within NGC 428 and it lacks well defined arms — a telltale sign of a galaxy merger. In 2015 the Hubble Space Telescope made a close-up shot of the galaxy with its Advanced Camera for Surveys and its Wide Field and Planetary Camera 2. The structure of NGC 428 has been compared to NGC 5645.
