UGC 8335 (Arp 238) is a pair of strongly interacting spiral galaxies. They have been distorted by extreme tidal forces, creating prominent tidal tails and a bridge of gas and stars between the galaxies. [4] [5]

UGC 8335 is about 400 million light-years from Earth, in the constellation Ursa Major. It is the 238th object in Halton Arp's Atlas of Peculiar Galaxies. [4]

Supernova

On 25 April 2012, Doug Rich discovered supernova SN 2012by in UGC 8335. [6] [7] At the time of discovery, the supernova had a magnitude of 17.6. [8] A peak magnitude measurement of 17.3 was recorded two days later, on April 27. [6] SN 2012by was classified as a type II supernova by Tomasella et al. at the Astronomical Observatory of Padova. The research group also found that its spectrum was similar to that of SN 1996as. [8]

The Pinwheel Galaxy is a face-on spiral galaxy 21 million light-years away from Earth in the constellation Ursa Major.

<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.

NGC 2535 is an unbarred spiral galaxy exhibiting a weak inner ring structure around the nucleus in the constellation Cancer that is interacting with NGC 2536. The interaction has warped the disk and spiral arms of NGC 2535, producing an elongated structure, visible at ultraviolet wavelengths, that contain many bright, recently formed blue star clusters in addition to enhanced star forming regions around the galaxy center. The two galaxies are listed together in the Atlas of Peculiar Galaxies as an example of a spiral galaxy with a high surface brightness companion.

NGC 2608 is a barred spiral galaxy located 93 million light-years away in the constellation Cancer. It is 62,000 light-years across, and about 60% of the width of the Milky Way. It is considered a grand design spiral galaxy and is classified as SB(s)b, meaning that the galaxy's arms wind moderately around the prominent central bar.

<span class="mw-page-title-main">NGC 936</span> Galaxy in the constellation Cetus

NGC 936 is a barred lenticular galaxy in the constellation Cetus. It is at a distance of about 60 million light-years away from Earth. Its nucleus and prominent bar have high surface brightness. Because of the shape of the prominent bar, the nucleus and the ring of stars at the end of the barrel, the galaxy has been compared with the shape of a TIE fighter, from the Star Wars universe, and thus NGC 936 has been named Darth Vader’s Galaxy or Darth Vader’s Starfighter. By measuring the radial velocity of the disc, Kormendy found in 1986 that the disc is stable, which is the reason why it is so smooth.

<span class="mw-page-title-main">NGC 2276</span> Galaxy in the constellation Cepheus

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. One of the many starburst spiral arms contains an intermediate mass black hole with 50,000 times the mass of the Sun, named NGC 2276-3c. NGC 2276-3c has produced two jets: a large-scale radio jet, approximately 2,000 light years long, and an "inner jet" about 6 light years long. The galaxy shows an enhanced rate of star formation that may have been triggered by a collision with a dwarf galaxy, or by the gravitational interaction with its neighbor compressing gas and dust.

<span class="mw-page-title-main">NGC 4490</span> Interacting galaxy in constellation Canes Venatici

NGC 4490, also known as the Cocoon Galaxy, is a barred spiral galaxy in the constellation Canes Venatici. William Herschel discovered it in 1788. It is known to be of the closest interacting/merging galactic system. The galaxy lies at a distance of 25 million light years from Earth making it located in the local universe. It interacts with its smaller companion NGC 4485 and as a result is a starburst galaxy. NGC 4490 and NGC 4485 are collectively known in the Atlas of Peculiar Galaxies as Arp 269. The two galaxies has already made their closest approach and are rushing away from each other. It's been discovered that NGC 4490 has a double nucleus.

NGC 2655 is a lenticular galaxy in the constellation Camelopardalis. It is at a distance of 60 million light years from Earth. NGC 2655 is a Seyfert galaxy. The galaxy has asymmetric dust lanes in the centre of the galaxy, tidal arms and extended neutral hydrogen gas and may have recently experienced a merger. The complex dynamics of the HI and optical tails suggest the galaxy may have undergone more mergers in the past. A weak bar has been detected in infrared H band. The diameter of the disk of the galaxy is estimated to be 60 Kpc.

NGC 3191 is a barred spiral galaxy in the constellation Ursa Major. It is located at a distance of about 400 million light years from Earth, which, given its apparent dimensions, means that NGC 3191 is about 115,000 light years across. The galaxy has been distorted and interacts with a companion 1.3 arcminutes to the west. An extremely blue tidal bridge lies between them. It was discovered by Gaia on 23 May 2017.

It was discovered by William Herschel on April 14, 1789.
