NGC 6124 (also known as Caldwell 75) is an open cluster located 1,860 light years away [1] in the constellation Scorpius. It was discovered by Abbe Lacaille in 1751 [2] during his South African tour.
The cluster is large and bright, with about 125 stars visible. [2]
Open Cluster NGC 2175 is an open cluster in the Orion constellation, embedded in a diffusion nebula. It was discovered by Giovanni Batista Hodierna before 1654 and independently discovered by Karl Christian Bruhns in 1857. NGC 2175 is at a distance of about 6,350 light years away from Earth.
NGC 2477 is an open cluster in the constellation Puppis. It contains about 300 stars, and was discovered by Abbé Lacaille in 1751. The cluster's age has been estimated at about 700 million years.
NGC 4309 is a lenticular galaxy located about 55 million light-years away in the constellation Virgo. The galaxy was discovered by astronomer Christian Peters in 1881 and is a member of the Virgo Cluster.
NGC 6709 is an open cluster of stars in the equatorial constellation of Aquila, some 5° to the southwest of the star Zeta Aquilae. It is situated toward the center of the galaxy at a distance of 3,510 light-years.
NGC 6755 is an open cluster of stars in the equatorial constellation of Aquila, positioned about 3° to the east of the star Delta Aquilae. It was discovered by the Anglo-German astronomer William Herschel on July 30, 1785 and is located at a distance of 8,060 light years from the Sun. NGC 6756 lies 30′ to the northeast of NGC 6755, with the pair forming a visual double cluster. However, they probably do not form a binary cluster system since they have different ages and are too distant from each other.
NGC 1851 is a relatively massive globular cluster located in the southern constellation of Columba. Astronomer John Dreyer described it as not very bright but very large, round, well resolved, and clearly consisting of stars. It is located 39.5 kilolight-years from the Sun, and 54.1 kilolight-years from the Galactic Center. The cluster is following a highly eccentric orbit through the galaxy, with an eccentricity of about 0.7.
NGC 4889 is an E4 supergiant elliptical galaxy. It was discovered in 1785 by the British astronomer Frederick William Herschel I, who catalogued it as a bright, nebulous patch. The brightest galaxy within the northern Coma Cluster, it is located at a median distance of 94 million parsecs from Earth. At the core of the galaxy is a supermassive black hole that heats the intracluster medium through the action of friction from infalling gases and dust. The gamma ray bursts from the galaxy extend out to several million light years of the cluster.
NGC 6819 is an open cluster located 7,200 light years away in the Cygnus constellation. It was discovered by Caroline Herschel on 12 May 1784.
NGC 2818 is a planetary nebula located in the southern constellation Pyxis. It consists largely of glowing gases from the star's outer layers ejected during the final stages of its life when it had run out of the fuel necessary to sustain its core fusion processes. The remnants of its core will remain as a white dwarf.
NGC 637 is an open cluster of stars in the northern constellation of Cassiopeia, positioned about 1.5° to the WNW of the star Epsilon Cassiopeiae. The cluster was discovered on 9 November 1787 by German-born English astronomer William Herschel. It is located in the Perseus Arm of the Milky Way, at a distance of approximately 7.045 kilolight-years from the Sun. The cluster is small but compact, and is readily visible in a small telescope.
NGC 4473 is an elliptical galaxy located about 50 million light-years away in the constellation of Coma Berenices. It was discovered by astronomer William Herschel on April 8, 1784. NGC 4473 has an inclination of about 71°. NGC 4473 is a member of a chain of galaxies called Markarian's Chain which is part of the larger Virgo Cluster of galaxies.
NGC 4506 is a spiral galaxy located around 50 million light-years away in the constellation Coma Berenices. It is classified as peculiar due to the presence of dust that surrounds its nucleus. NGC 4506 was discovered by astronomer William Herschel on January 14, 1787. It is a member of the Virgo Cluster.
NGC 4570 is an edge-on lenticular galaxy located about 57 million light-years away in the constellation Virgo. NGC 4570 was discovered by astronomer William Herschel on April 13, 1784 and is a member of the Virgo Cluster.
NGC 4709 is an elliptical galaxy located in the constellation Centaurus. It is considered to be a member of the Centaurus Cluster and is the dominant member of a small group of galaxies known as "Cen 45" which is currently merging with the main Centaurus Cluster even though the two subclusters' line of sight redshift velocities differ by about 1500 km/s. NGC 4709 was discovered by astronomer James Dunlop on May 7, 1826.
NGC 709 is a lenticular galaxy located 150 million light-years away in the constellation Andromeda. It was discovered by the Irish engineer and astronomer Bindon Blood Stoney on October 28, 1850 and is a member of the galaxy cluster Abell 262.
NGC 4294 is a barred spiral galaxy with flocculent spiral arms located about 55 million light-years away in the constellation Virgo. The galaxy was discovered by astronomer William Herschel on March 15, 1784 and is a member of the Virgo Cluster.
NGC 4299 is a featureless spiral galaxy located about 55 million light-years away in the constellation Virgo. It was discovered by astronomer William Herschel on March 15, 1784 and is a member of the Virgo Cluster.
NGC 4297 is a lenticular galaxy located about 200 million light-years away in the constellation Virgo. It was discovered by astronomer William Herschel on April 13, 1784. It forms an interacting pair with NGC 4296.
NGC 4326 is a barred spiral galaxy with a ring located about 330 million light-years away in the constellation Virgo. It was discovered by astronomer William Herschel on April 13, 1784, who described it as "vF, S, R, bM, 1st of 3". It is a large galaxy, with a diameter of around 200,000 ly (61 kpc) making it nearly twice the size of the Milky Way. NGC 4326 is also classified as a LINER galaxy. Despite being listed in the Virgo Cluster catalog as VCC 623, it is not a member of the Virgo Cluster but instead a background galaxy.
NGC 4333 is a barred spiral galaxy with a ring structure located about 330 million light-years away in the constellation Virgo. It was discovered by astronomer William Herschel on April 13, 1784, who described it as "F, pS, R, bM, 2nd of 3". NGC 4333 is also classified as a LINER galaxy. Despite being listed in the Virgo Cluster catalog as VCC 637, it is not a member of the Virgo Cluster but instead a background galaxy.
