IC 4271 is a spiral galaxy located some 800 million light-years away in the Canes Venatici constellation. It is 130,000 light-years in diameter. IC 4271 was first located on July 10, 1896, by Stephane Javelle, a French astronomer. It hosts a Seyfert type 2 nucleus, containing an acceleration disc around its supermassive black hole which releases large amounts of radiation, hence its bright appearance. IC 4271 appears to be interacting with its smaller neighboring galaxy, PGC 3096774.

IC 21 known as PGC 1785, is a distant barred spiral galaxy located in the Cetus constellation. It is located 822 million light-years away and has an estimated diameter of 120,000 light-years. IC 21 was first found by Stephane Javelle, who was a French astronomer on November 7th in 1891. The galaxy is apparently located near towards a dwarf galaxy, PGC 3112047. According to SIMBAD database, IC 21 is both a Seyfert type 2 and radio galaxy, suggesting an active galactic nucleus.

<span class="mw-page-title-main">PGC 29820</span> Galaxy located in the constellation Sextans

PGC 29820 is a spiral galaxy located 600 million light-years away from the solar system in the Sextans constellation. It is about 120,000 thousand light-years in diameter and has high amounts of star formation rates. The reason is due to the ram pressure, which enables the dense gas to be compressed which eventually collapses to form new stars. Not only to mention, the galaxy's tendrils are also created, hence astronomers calling it a jellyfish galaxy. According to SIMBAD, it is classified as a Seyfert 2 galaxy which it contains an active nucleus.

PGC 65543, is a spiral galaxy, with extensive star forming regions, located in Indus. It is 650 million light-years away from the solar system and approximately measuring 90,000 light-years in diameter. The tidal interactions from certain galaxies which PGC 65543 is moving towards to, have caused it to get distorted. Its star-forming gas and dust are dynamically stripped and formed into tendrils that stretch outwards, thus gives an appearance of a jellyfish galaxy.

PGC 1228197 known as WINGS J211347.41+022834.9 and JO206, is a large spiral galaxy located 700 million light-years away towards the constellation of Aquarius. The galaxy is estimated to be at least 160,000 thousand light-years in diameter, making it somehow bigger than the Milky Way. With a radial velocity of 15,200 kilometers per second, it is slowly drifting away. It is classified as a jellyfish galaxy, mainly due to interactions from other galaxies, causing it to run into intracluster medium and stripping the gas from it, which causes long galactic tendrils of stars. It has an active galactic nucleus according to SIMBAD.

PGC 4789 is a distant barred spiral galaxy in the Pisces constellation. It is located 675 million light-years from the Milky Way and seems to be interacting with its neighboring galaxies. it is known as Arp 48 in the Atlas of Peculiar Galaxies catalogue. In this class, PGC 4789 falls into galaxies that have at least one low surface brightness companion.

<span class="mw-page-title-main">PGC 2456</span> Galaxy in the constellation Cetus

PGC 2456 known as KAZ 364 and JO201, is a spiral galaxy located in the constellation of Cetus. A member of Abell 85 galaxy cluster, it is located 617 million light-years away from the solar system and is considered a jellyfish galaxy due to the fact the tendrils are seen drifting downwards from its core. This mainly occurs when such galaxies like PGC 2456, moves through high speeds across the galaxy clusters, causing ram pressure to stripped gas, thus forming tendrils full of star formation. It is listed as a Seyfert galaxy by SIMBAD, meaning it has an active galactic nucleus. PGC 2456 lies 360 kiloparsecs from the brightest cluster galaxy, Holmberg 15A.

<span class="mw-page-title-main">IC 5337</span> Galaxy in the constellation Pegasus

IC 5337 or JW100, is a spiral galaxy located 800 million light-years away from the solar system in the constellation of Pegasus. It is probably gravitationally bound to IC 5338, the brightest cluster galaxy in Abell 2626. IC 5337 is a jellyfish galaxy, mainly due to dynamic stripping pressure. Star-forming gas are thrown about, as the galaxy penetrates through the thin gas layer and causing them to drip from the galaxy's disc, giving it its unique appearance of a cosmic jellyfish. In the image, other galaxies can be seen in the background.

IC 3686 is a Sc type spiral galaxy located 920 million light-years from the solar system in the constellation of Virgo. It was discovered by American astronomer, Royal Harwood Frost on May 10, 1904. Frost described it as magnitude 14.3 and RA 12 42 at 36.0, Dec +11 44 22. IC 3686 has an estimated diameter of 270,000 light-years making it larger compared to the Milky Way. and is classified as LINER-type active galactic nucleus galaxy according to SIMBAD. Despite listed in the Virgo Cluster catalogue as VCC 1927, it is not a member of the Virgo Cluster but a background galaxy.
