Centaurus A is a galaxy in the constellation of Centaurus. It was discovered in 1826 by Scottish astronomer James Dunlop from his home in Parramatta, in New South Wales, Australia. There is considerable debate in the literature regarding the galaxy's fundamental properties such as its Hubble type and distance. NGC 5128 is one of the closest radio galaxies to Earth, so its active galactic nucleus has been extensively studied by professional astronomers. The galaxy is also the fifth-brightest in the sky, making it an ideal amateur astronomy target. It is only visible from the southern hemisphere and low northern latitudes.
NGC 5866 is a relatively bright lenticular galaxy in the constellation Draco. NGC 5866 was most likely discovered by Pierre Méchain or Charles Messier in 1781, and independently found by William Herschel in 1788. Measured orbital velocities of its globular cluster system imply that dark matter makes up only 34±45% of the mass within 5 effective radii, a notable paucity.
NGC 5010 is a lenticular galaxy located about 140 million light years away in the constellation Virgo. It was discovered by John Herschel on May 9, 1831. It is considered a Luminous Infrared Galaxy (LIRG). As the galaxy has few young blue stars and mostly red old stars and dust, it is transitioning from being a spiral galaxy to being an elliptical galaxy, with its spiral arms having burned out and become dusty arms. From the perspective of Earth, the galaxy is facing nearly edge-on.
NGC 3607 is a small but fairly bright lenticular galaxy in the equatorial constellation of Leo, about 2.5° south of the prominent star Delta Leonis. The galaxy was discovered March 14, 1784 by William Herschel. Dreyer described it as "very bright, large, round, very much brighter middle, 2nd of 3". It is located at a distance of 73 million light years and is receding with a radial velocity of 930 km/s. The galaxy lies southwest of NGC 3626 at an angular separation of ~50′. It occupies the center of the Leo II Group of galaxies, forming one of its two brightest members – the other being NGC 3608. It is a member of the NGC 3607 Group of galaxies, which is a member of the Leo II Groups, a series of galaxies and galaxy clusters strung out from the right edge of the Virgo Supercluster.
The 2MASX J00482185−2507365 occulting pair is a pair of overlapping spiral galaxies found in the vicinity of NGC 253, the Sculptor Galaxy. Both galaxies are more distant than NGC 253, with the background galaxy, 2MASX J00482185−2507365, lying at redshift z=0.06, about 800 million light-years from Earth, and the foreground galaxy lying between NGC 253 and the background galaxy.
NGC 7332 is an edge-on peculiar lenticular galaxy located about 67 million light-years away in the constellation Pegasus. It possesses a -shaped bulge, associated with stellar bar. It was discovered on September 19, 1784 by the astronomer William Herschel.
NGC 4452 is an edge-on lenticular galaxy that is part of the Virgo Cluster. NGC 4452 is about 60 million light-years (18 Mpc) away from Earth and 35 kly (11 kpc) in diameter. This galaxy was first seen by William Herschel in 1784 with his 47 cm (19 in) telescope.
NGC 2768 is a lenticular galaxy located in the constellation of Ursa Major. It is at a distance of 65 million light years from Earth. NGC 2768 is an example of a Seyfert galaxy, an object with a supermassive black hole at its centre. A dusty structure is encircling the centre of the galaxy, forming a knotted ring around the galaxy's brightly glowing middle. This ring lies perpendicular to the plane of NGC 2768 itself, stretching up and out of the galaxy. The dust in NGC 2768 forms an intricate network of knots and filaments.
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 7022 is a barred lenticular galaxy located about 95 million light-years away from Earth in the constellation Indus. The galaxy was discovered by astronomer John Herschel on October 2, 1834.
NGC 7029 is an elliptical galaxy located about 120 million light-years away from Earth in the constellation Indus. NGC 7029 has an estimated diameter of 129,000 light-years. It was discovered by astronomer John Herschel on October 10, 1834. It is in a pair of galaxies with NGC 7022.
NGC 7033 is a lenticular galaxy located about 390 million light-years away in the constellation of Pegasus. It is part of a pair of galaxies that contains the nearby galaxy NGC 7034. NGC 7033 was discovered by astronomer Albert Marth on September 17, 1863.
NGC 7041 is a lenticular galaxy located about 80 million light-years away in the constellation of Indus. NGC 7041 was discovered by astronomer John Herschel on July 7, 1834.
NGC 7079 is a barred lenticular galaxy located about 110.58 million light-years away in the constellation of Grus. NGC 7079 is also classified as a LINER galaxy. It is tilted about 51° to the Earth's line of sight. NGC 7079 was discovered by astronomer John Herschel on September 6, 1834.
NGC 612 is a lenticular galaxy in the constellation of Sculptor located approximately 388 million light-years from Earth. It is a type II Seyfert galaxy and thus has an active galactic nucleus. NGC 612 has been identified as an extremely rare example of a non-elliptical radio galaxy, hosting one of the nearest powerful FR-II radio sources.
NGC 5982 is an elliptical galaxy located in the constellation Draco. It is located at a distance of circa 130 million light years from Earth, which, given its apparent dimensions, means that NGC 5982 is about 100,000 light years across. It was discovered by William Herschel on May 25, 1788.
NGC 3640 is an elliptical galaxy located in the constellation Leo. It is located at a distance of circa 75 million light years from Earth, which, given its apparent dimensions, means that NGC 3640 is about 90,000 light years across. It was discovered by William Herschel on February 23, 1784. It is a member of the NGC 3640 Group of galaxies, which is a member of the Leo II Groups, a series of galaxies and galaxy clusters strung out from the right edge of the Virgo Supercluster.
NGC 5363 is a lenticular galaxy located in the constellation Virgo. It is located at a distance of circa 65 million light years from Earth, which, given its apparent dimensions, means that NGC 5363 is about 100,000 light years across. It was discovered by William Herschel on January 19, 1784. It is a member of the NGC 5364 Group of galaxies, itself one of the Virgo III Groups strung out to the east of the Virgo Supercluster of galaxies.
NGC 676 is a lenticular Seyfert 2 galaxy about 18.7 Mly away in the constellation Pisces. It can be seen near the star α Piscium. Located close to the celestial equator, it is visible from both hemispheres. BD +04 0244, a star with a visual magnitude of 10.44, is superposed 5.1 arc seconds south-southwest of the nucleus. It is one of the 621 galaxies described in Marat Arakelian's catalog of high-surface-brightness galaxies.
NGC 2293 is a lenticular galaxy located in the constellation Canis Major. It is located at a distance of circa 100 million light years from Earth, which, given its apparent dimensions, means that NGC 2293 is about 160,000 light years across. It was discovered by John Herschel on January 20, 1835. NGC 2293 forms a pair with NGC 2292 and has an HI ring that surrounds both galaxies.
