Albert Marth
Albert Marth (5 May 1828 – 6 August 1897) was a German astronomer who worked in Britain and Ireland.
Apparent magnitude
Apparent magnitude is a measure of the brightness of a star or other astronomical object.
See NGC 7028 and Apparent magnitude
Constellation
A constellation is an area on the celestial sphere in which a group of visible stars forms a perceived pattern or outline, typically representing an animal, mythological subject, or inanimate object.
See NGC 7028 and Constellation
Declination
In astronomy, declination (abbreviated dec; symbol δ) is one of the two angles that locate a point on the celestial sphere in the equatorial coordinate system, the other being hour angle.
Delphinus
Delphinus (Pronounced or) is a small constellation in the Northern Celestial Hemisphere, close to the celestial equator.
Epoch (astronomy)
In astronomy, an epoch or reference epoch is a moment in time used as a reference point for some time-varying astronomical quantity.
See NGC 7028 and Epoch (astronomy)
Infrared Processing and Analysis Center
The Infrared Processing and Analysis Center (IPAC) provides science operations, data management, data archives and community support for astronomy and planetary science missions.
See NGC 7028 and Infrared Processing and Analysis Center
Minute and second of arc
A minute of arc, arcminute (arcmin), arc minute, or minute arc, denoted by the symbol, is a unit of angular measurement equal to of one degree.
See NGC 7028 and Minute and second of arc
NASA
The National Aeronautics and Space Administration (NASA) is an independent agency of the U.S. federal government responsible for the civil space program, aeronautics research, and space research.
New General Catalogue
The New General Catalogue of Nebulae and Clusters of Stars (abbreviated NGC) is an astronomical catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888. NGC 7028 and New General Catalogue are NGC objects.
See NGC 7028 and New General Catalogue
Right ascension
Right ascension (abbreviated RA; symbol) is the angular distance of a particular point measured eastward along the celestial equator from the Sun at the March equinox to the (hour circle of the) point in question above the Earth.
See NGC 7028 and Right ascension
Spiral galaxy
Spiral galaxies form a class of galaxy originally described by Edwin Hubble in his 1936 work The Realm of the Nebulae (pp. 124–151) and, as such, form part of the Hubble sequence.
