ESO 269-57 is a large barred spiral galaxy located about 150 million light-years away [2] in the constellation Centaurus. ESO 269-57 has a diameter of about 200,000 light-years. [3] It is part of group of galaxies known as LGG 342. [4] [5] which is also known as the NGC 5064 Group [6] [4] which is part of the Centaurus Supercluster. [6]
ESO 269-57 has an inner ring surrounding its bright center and connected by its bar. The ring is made up of several tightly wound spiral arms. Surrounding the inner ring, are two outer arms made up of star-forming regions that appear to split into several branches of arms. [3]
On March 3, 1992 a type Ia supernova was discovered in ESO 269-57. [7]
NGC 7060 is an intermediate spiral galaxy located about 200 million light-years away in the constellation of Microscopium. The spiral arms of NGC 7060 appear to overlap. NGC 7060 was discovered by astronomer John Herschel on September 2, 1836.
NGC 4683 is a barred lenticular galaxy located about 170 million light-years away in the constellation Centaurus. It was discovered by astronomer John Herschel on June 8, 1834. NGC 4683 is a member of the Centaurus Cluster.
NGC 4706 is a lenticular galaxy located about 157 million light-years away in the constellation Centaurus. It was discovered by astronomer John Herschel on June 5, 1834. NGC 4706 is a member of the Centaurus Cluster.
NGC 4729 is an elliptical galaxy located about 160 million light-years away in the constellation Centaurus. NGC 4729 was discovered by astronomer John Herschel on June 8, 1834 and is a member of the Centaurus Cluster.
NGC 4730 is a lenticular galaxy located about 160 million light-years away in the constellation Centaurus. NGC 4730 was discovered by astronomer John Herschel on June 8, 1834. NGC 4730 is a member of the Centaurus Cluster.
NGC 4744 is a barred lenticular galaxy located about 160 million light-years away in the constellation Centaurus. NGC 4744 was discovered by astronomer John Herschel on June 8, 1834. It is a member of the Centaurus Cluster.
NGC 1268 is a spiral galaxy located about 140 million light-years away in the constellation Perseus. It was discovered by astronomer Heinrich d'Arrest on February 14, 1863. NGC 1268 is a member of the Perseus Cluster and appears to show signs of distortion in the form of bridges. These features may be the result of a strong interaction with NGC 1267.

The Telescopium−Grus Cloud is a galaxy filament in the constellations of Pavo, Indus, and Telescopium. It was first defined by astronomer Brent Tully in his book The Nearby Galaxies Atlas and its companion book The Nearby Galaxies Catalog.
NGC 4324 is a lenticular galaxy located about 85 million light-years away in the constellation Virgo. It was discovered by astronomer Heinrich d'Arrest on March 4, 1862. NGC 4324 has a stellar mass of 5.62 × 1010M☉, and a baryonic mass of 5.88 × 1010M☉. The galaxy's total mass is around 5.25 × 1011M☉.
