NGC 592 is an H II region type emission nebula located in the Triangulum galaxy (M33) and thus in the constellation of Triangulum. [1] [4] The nebula contains an open cluster of stars and is approximately 2.86 million light-years away from Earth. [4] [3] [2]

Observation history

NGC 592 was discovered by German astronomer Heinrich Louis d'Arrest on October 2, 1861. [4] John Louis Emil Dreyer, compiler of the first New General Catalogue of Nebulae and Clusters of Stars, described NGC 592 as "faint" and "pretty large." [4]

Physical characteristics

NGC 592 is around ten times less luminous than NGC 604, a neighbouring emission nebula and one of the largest H II regions in the Local Group of galaxies. It is relatively close to the galactic centre of M33 and is located on the outer part of one of its spiral arms. The central region of NGC 592 is estimated to be 4.9 ± 0.5 million years old and have a stellar mass of 16500 ± 5200 M☉ . Several massive stars have been discovered within NGC 592, including at least four Wolf-Rayet type stars. The nebula is also estimated to contain 8 ± 4 O- and B- type stars. [5]

Triangulum Galaxy Spiral galaxy in the constellation Triangulum

The Triangulum Galaxy is a spiral galaxy 2.73 million light-years (ly) from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC 598. The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Andromeda Galaxy and the Milky Way. It is one of the most distant permanent objects that can be viewed with the naked eye.

NGC 604 H II region inside the Triangulum Galaxy

NGC 604 is an H II region inside the Triangulum Galaxy. It was discovered by William Herschel on September 11, 1784. It is among the largest H II regions in the Local Group of galaxies; at the galaxy's estimated distance of 2.7 million light-years, its longest diameter is roughly 1,520 light years (~460 parsecs), over 40 times the size of the visible portion of the Orion Nebula. It is over 6,300 times more luminous than the Orion Nebula, and if it were at the same distance it would outshine Venus. Its gas is ionized by a cluster of massive stars at its center with 200 stars of spectral type O and WR, a mass of 105 solar masses, and an age of 3.5 million years; however, unlike the Large Magellanic Cloud's Tarantula Nebula central cluster (R136), NGC 604's one is much less compact and more similar to a large stellar association.

NGC 4309 Lenticular galaxy in the constellation Virgo

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.

IC 2177 Region of nebulosity in Monoceros constellation

IC 2177 is a region of nebulosity that lies along the border between the constellations Monoceros and Canis Major. It is a roughly circular H II region centered on the Be star HD 53367. This nebula was discovered by Welsh amateur astronomer Isaac Roberts and was described by him as "pretty bright, extremely large, irregularly round, very diffuse."

NGC 4762 Lenticular galaxy in the constellation Virgo

NGC 4762 is an edge-on lenticular galaxy in the constellation Virgo. It is at a distance of 60 million light years and is a member of the Virgo Cluster. The edge-on view of this particular galaxy, originally considered to be a barred spiral galaxy, makes it difficult to determine its true shape, but it is considered that the galaxy consists of four main components — a central bulge, a bar, a thick disc and an outer ring. The galaxy's disc is asymmetric and warped, which could be explained by NGC 4762 mergering with a smaller galaxy in the past. The remains of this former companion may then have settled within NGC 4762's disc, redistributing the gas and stars and so changing the disc's morphology.

NGC 4540 Spiral galaxy in the constellation Coma Berenices

NGC 4540 is a spiral galaxy with type 1 seyfert activity located about 64 million light-years away in the constellation Coma Berenices. NGC 4540 was discovered by astronomer William Herschel on March 21, 1784 and is member of the Virgo Cluster.

NGC 3859 Spiral galaxy in the constellation Leo

NGC 3859 is a spiral galaxy located about 295 million light-years away in the constellation Leo. It was discovered by astronomer Édouard Stephan on March 23, 1884. The galaxy is a member of the Leo Cluster.

NGC 3873 Elliptical galaxy in the constellation Leo

NGC 3873 is an elliptical galaxy located about 300 million light-years away in the constellation Leo. The galaxy was discovered by astronomer Heinrich d'Arrest on May 8, 1864. NGC 3873 is a member of the Leo Cluster.

NGC 4212 Spiral galaxy in the constellation Coma Berenices

NGC 4212 is a flocculent spiral galaxy with LINER activity located about 53 million light-years away in the constellation Coma Berenices. The galaxy was discovered by astronomer William Herschel on April 8, 1784 and was listed in the NGC catalog as NGC 4208. He then observed the same galaxy and listed it as NGC 4212. Astronomer John Louis Emil Dreyer later concluded that NGC 4208 was identical to NGC 4212. NGC 4212 is a member of the Virgo Cluster.

NGC 6061 Lenticular galaxy in the constellation Hercules

NGC 6061 is a lenticular galaxy with radio activity located about 490 million light-years away in the constellation Hercules. The galaxy is classified as a head-tail radio galaxy and was discovered by astronomer Lewis Swift on June 8, 1886. NGC 6061 is a member of the Hercules Cluster.

NGC 612 Spiral galaxy in the constellation Sculptor

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 643 Star cluster in the constrellation Hydrus

NGC 643 is an open cluster located on the far outskirts of the Small Magellanic Cloud in the southern constellation of Hydrus, approximately 200,000 light-years from Earth. Due to their close proximity to NGC 643, the open cluster ESO 29-SC44 and the galaxies PGC 6117 and PGC 6256 are also designated NGC 643A, NGC 643B and NGC 643C, respectively. NGC 643 is relatively old. Its brightest stars have an apparent magnitude of 19.
