NGC 383 is a double radio galaxy [3] with a quasar-like appearance located in the constellation Pisces. It was discovered by German-British astronomer William Herschel on 12 September 1784. [4] It is listed as Arp 331 in Halton Arp's Atlas of Peculiar Galaxies. [5]

Recent discoveries by the National Radio Astronomy Observatory in 2006 reveal that NGC 383 is being bisected by high energy relativistic jets traveling at relatively high fractions of the speed of light. The relativistic electrons in the jets are detected as synchrotron radiation in the x-ray and radio wavelengths. The focus of this intense energy is the galactic center of NGC 383. The relativistic electron jets detected as synchrotron radiation extend for several thousand parsecs and then appear to dissipate at the ends in the form of streamers or filaments.

There are four other nearby galaxies NGC 379, NGC 380, NGC 385, and NGC 384 which are suspected of being closely associated with NGC 383, as well as several other galaxies at relatively close distance.

Two supernovae have been observed in NGC 383:

Arp 271 is a pair of similarly sized interacting spiral galaxies, NGC 5426 and NGC 5427, in the constellation of Virgo. It is not certain whether the galaxies are going to eventually collide or not. They will continue interacting for tens of millions of years, creating new stars as a result of the mutual gravitational attraction between the galaxies, a pull seen in the bridge of stars already connecting the two. Located about 130 million light-years away, the Arp 271 pair is about 130,000 light-years across. It was originally discovered in 1785 by William Herschel. It is speculated, that the Milky Way will undergo a similar collision in about five billion years with the neighbouring Andromeda Galaxy, which is currently located about 2.6 million light-years away.

NGC 7714 is a spiral galaxy in the constellation Pisces. Its velocity with respect to the cosmic microwave background is 2430 ± 26 km/s, which corresponds to a Hubble distance of 116.9 ± 8.3 Mly (35.85 ± 2.54 Mpc). In addition, five non-redshift measurements give a distance of 92.24 ± 8.69 Mly (28.280 ± 2.664 Mpc). It was discovered by British astronomer John Herschel on 18 September 1830.

<span class="mw-page-title-main">Arp 273</span> Pair of interacting galaxies in the constellation Andromeda

Arp 273 is a pair of interacting galaxies, 300 million light years away in the constellation Andromeda. It was first described in the Atlas of Peculiar Galaxies, compiled by Halton Arp in 1966. The larger of the spiral galaxies, known as UGC 1810, is about five times more massive than the smaller galaxy. It has a disc that is tidally distorted into a rose-like shape by the gravitational pull of the companion galaxy below it, known as UGC 1813. The smaller galaxy shows distinct signs of active star formation at its nucleus, and "it is thought that the smaller galaxy has actually passed through the larger one."

NGC 2276 is an intermediate spiral galaxy in the constellation Cepheus. The galaxy lies 120 million light-years away from Earth. NGC 2276 has an asymmetrical appearance, most likely caused by gravitational interactions with its neighbor, elliptical galaxy NGC 2300. NGC 2276 is traveling with an orbital velocity of about 968 km/s due to its neighbor. Trailing NGC 2276 is a long tail of interstellar medium about 300,000 light-years long, formed by ram pressure stripping.
