ESO 137-001 is a barred spiral galaxy located in the constellation Triangulum Australe and in the cluster Abell 3627. As the galaxy moves to the center of the cluster at 1900 km/s, it is stripped by hot gas, thus creating a 260,000 light-year long tail. This is called ram pressure stripping. The intergalactic gas in Abell 3627 is at 100 million Kelvin, which causes star formation in the tails.
UGC 2885 is a large barred spiral galaxy of type SA(rs)c in the constellation Perseus. It is 232 million light-years (71 Mpc) from Earth and measures 463,000 ly (142,000 pc) across, making it one of the largest known spiral galaxies. It is also a possible member of the Pisces-Perseus supercluster.
NGC 4402 is a relatively near, edge-on spiral galaxy located around 50 million light-years from Earth. It is in the constellation of Virgo within the Virgo Cluster of galaxies. It can be seen when viewing Markarian's Chain.
NGC 7013 is a relatively nearby spiral or lenticular galaxy estimated to be around 37 to 41.4 million light-years away from Earth in the constellation of Cygnus. NGC 7013 was discovered by English astronomer William Herschel on July 17, 1784 and was also observed by his son, astronomer John Herschel on September 15, 1828.
NGC 7020 is a barred lenticular galaxy located about 140 million light-years away in the constellation Pavo. NGC 7020 was discovered by astronomer John Herschel on August 31, 1836.
Arp 256 is a pair of interacting barred spiral galaxies located 380 million light years away from Earth in the constellation of Cetus. Arp 256 refers to the southern galaxy; the northern galaxy is Arp 256N.
NGC 3981 is an unbarred spiral galaxy located 62 million light-years away in the constellation of Crater. It was discovered on February 7, 1785 by William Herschel.
IC 4141 is a spiral galaxy in the constellation of Coma Berenices. The galaxy is located 900 million light-years away from Earth. Founded in 1904 by German astronomer Max Wolf, it measures 255,000 light-years across in diameter. With a radial velocity of 19,000 kilometers per second, it is slowly drifting from the solar system.
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 thousand 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.
PGC 2387685 is a peculiar galaxy located 440 million light-years in the Hercules constellation. The galaxy seems to be gravitationally interacting with another neighboring galaxy PGC 3087279, which in turn causes both of the galaxies to have distorted shapes. Together, they form the galaxy pair, ZW I 136.
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.
UGC 11105 known as PGC 61361, is a relatively nearby spiral galaxy located 109 million light-years away in the Hercules constellation. It is less luminous in appearance. The supernova that occurred in UGC 11105 in 2019, has long faded. It is outshone by the bright stars shown in the foreground. From the perspective on Earth, the Sun is 14 thousand trillion times brighter as compared to UGC 1105, if we to calculate the apparent magnitude for both objects. It is a possible active galactic nucleus candidate, according to SIMBAD.
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.
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 thousand 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.
NGC 5008 is a massive barred spiral galaxy located in the Boötes constellation.
IC 4040 is a type SABc spiral galaxy with a bar in Coma Berenices. It is located 353 million light-years away from the solar system and has an estimated diameter of 105,000 light-years making it slightly larger than the Milky Way. IC 4040 was discovered on April 12, 1891, by Guillaume Bigourdan and is a member of the Coma Cluster.
IC 2431 are a group of interacting galaxies in the constellation of Cancer. They are located 684 million light-years away from the solar system and were discovered on February 24, 1896, by Stephane Javelle.
IC 1182 is a type S0-a lenticular galaxy located in Hercules. It is located 464 million light-years away from the Solar System and was discovered on August 11, 1892, by Stephane Javelle. IC 1198 is a member of the Hercules Cluster, which is a part of the CfA 2 Great Wall.
