NGC 506 is a star in the constellation Pisces. [1] It was discovered on 7 November 1874 by Lawrence Parsons, the 4th Earl of Rosse. [2]

Star Astronomical object

A star is an astronomical object consisting of a luminous spheroid of plasma held together by its own gravity. The nearest star to Earth is the Sun. Many other stars are visible to the naked eye from Earth during the night, appearing as a multitude of fixed luminous points in the sky due to their immense distance from Earth. Historically, the most prominent stars were grouped into constellations and asterisms, the brightest of which gained proper names. Astronomers have assembled star catalogues that identify the known stars and provide standardized stellar designations. The observable Universe contains an estimated 1×1024 stars, but most are invisible to the naked eye from Earth, including all stars outside our galaxy, the Milky Way.

Pisces (constellation) Zodiac constellation straddling the celestial equator

Pisces is a constellation of the zodiac. Its name is the Latin plural for fish. It lies between Aquarius to the west and Aries to the east. The ecliptic and the celestial equator intersect within this constellation and in Virgo. Its symbol is .

Lawrence Parsons, 4th Earl of Rosse British astronomer

Lawrence Parsons, 4th Earl of Rosse, KP, FRS was a member of the Irish peerage and an amateur astronomer. His name is often given as Laurence Parsons.

Observation history

Lawrence discovered the object during his last observation of the NGC 499 Group. Though he noted no description, he gave a micrometric measure setting the object's position relative to a different nearby star. There is no object at this position, but the NGC position is corrected further southeast which leads to the assumption that John Louis Emil Dreyer, creator of the New General Catalogue, had additional information when he catalogued the star. [3] In the catalogue, the object is described as "very faint, very small, southwest of NGC 507". [2]

<i>New General Catalogue</i> astronomical catalogue of deep sky objects

The New General Catalogue of Nebulae and Clusters of Stars is a catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888. It expands upon the cataloguing work of William and Caroline Herschel, and John Herschel's General Catalogue of Nebulae and Clusters of Stars. The NGC contains 7,840 objects, known as the NGC objects. It is one of the largest comprehensive catalogues, as it includes all types of deep space objects, including galaxies, star clusters, emission nebulae and absorption nebulae. Dreyer also published two supplements to the NGC in 1895 and 1908, known as the Index Catalogues, describing a further 5,386 astronomical objects.

NGC 46 star in Pisces constellation

NGC 46, occasionally referred to as PGC 5067596, is an F8 star located approximately 962 ± 281 light-years from the Solar System in the constellation Pisces. It was first discovered on October 22, 1852 by Irish astronomer Edward Joshua Cooper, who incorrectly identified it as a nebula.

NGC 462 galaxy

NGC 462 is an elliptical galaxy located in the Pisces constellation. It was discovered by Albert Marth on 23 October 1864. Dreyer, creator of the New General Catalogue, originally described it as "extremely faint, very small, stellar". The word stellar clearly suggests an initial misidentification of NGC 462 as a star.

NGC 459 galaxy

NGC 459, also known as UGC 832, MCG 3-4-17, ZWG 459.24, and PGC 4665, is a spiral galaxy in the constellation Pisces. It was discovered on October 15, 1784, by William Herschel. It was described as being extremely faint by John Dreyer in the New General Catalogue.

NGC 507 galaxy

NGC 507, also known as rp 229, CGCG 502-67, MCG 5-4-44, PGC 5098, UGC 938, and V V 207, is a lenticular galaxy in the constellation Pisces. It was described as being "very faint", "pretty large", "round", "brighter in the middle", and "south of NGC 508" by John Dreyer in the New General Catalogue. It was discovered by William Herschel on September 12, 1784.

NGC 486 elliptical galaxy in the constellation Pisces

NGC 486, also occasionally referred to as LEDA 1281966 or GC 275, is a spiral galaxy in the constellation Pisces. NGC 486 was discovered on December 6, 1850 by Irish engineer Bindon Blood Stoney.

NGC 490 galaxy

NGC 490, also occasionally referred to as PGC 4973 or GC 277, is a lenticular galaxy in the constellation Pisces. It is located approximately 85 million light-years from Earth and was discovered on December 6, 1850, by Irish engineer Bindon Blood Stoney. Although John Dreyer, creator of the New General Catalogue, credits the discovery to astronomer William Parsons, he notes that many of his claimed discoveries were made by one of his assistants. In the case of NGC 490, the discovery was made by Bindon Stoney, who discovered it along with NGC 486, NGC 492 and NGC 500 during his observation of NGC 488.

NGC 492 galaxy

NGC 492, also occasionally referred to as PGC 4976 or GC 280, is a barred spiral galaxy in the constellation Pisces. It is located approximately 590 million light-years from Earth and was discovered on December 6, 1850 by Irish engineer Bindon Blood Stoney. Although John Dreyer, creator of the New General Catalogue, credits the discovery to astronomer William Parsons, 3rd Earl of Rosse, he notes that many of his claimed discoveries were made by one of his assistants. In the case of NGC 492, the discovery was made by Bindon Stoney, who discovered it along with NGC 486, NGC 490 and NGC 500 during his observation of NGC 488 using Lord Rosse's 72" telescope.
