Capricornus
Capricornus is one of the constellations of the zodiac.
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 6907 and Epoch (astronomy)
Galaxy group
A galaxy group or group of galaxies (GrG) is an aggregation of galaxies comprising about 50 or fewer gravitationally bound members, each at least as luminous as the Milky Way (about 1010 times the luminosity of the Sun); collections of galaxies larger than groups that are first-order clustering are called galaxy clusters.
Galaxy merger
Galaxy mergers can occur when two (or more) galaxies collide.
See NGC 6907 and Galaxy merger
GALEX
Galaxy Evolution Explorer (GALEX or Explorer 83 or SMEX-7) was a NASA orbiting space telescope designed to observe the universe in ultraviolet wavelengths to measure the history of star formation in the universe.
Grand design spiral galaxy
A grand design spiral galaxy is a type of spiral galaxy with prominent and well-defined spiral arms, as opposed to multi-arm and flocculent spirals which have subtler structural features.
See NGC 6907 and Grand design spiral galaxy
H II region
An H II region or HII region is a region of interstellar atomic hydrogen that is ionized.
Infrared
Infrared (IR; sometimes called infrared light) is electromagnetic radiation (EMR) with wavelengths longer than that of visible light but shorter than microwaves.
International Astronomical Union
The International Astronomical Union (IAU; Union astronomique internationale, UAI) is an international non-governmental organization (INGO) with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation.
See NGC 6907 and International Astronomical Union
IRAS
The Infrared Astronomical Satellite (Dutch: Infrarood Astronomische Satelliet) (IRAS) was the first space telescope to perform a survey of the entire night sky at infrared wavelengths.
Kilometre
The kilometre (SI symbol: km; or), spelt kilometer in American English and Philippine English, is a unit of length in the International System of Units (SI), equal to one thousand metres (kilo- being the SI prefix for). It is the preferred measurement unit to express distances between geographical places on land in most of the world; notable exceptions are the United States and the United Kingdom where the statute mile is used.
Lenticular galaxy
A lenticular galaxy (denoted S0) is a type of galaxy intermediate between an elliptical (denoted E) and a spiral galaxy in galaxy morphological classification schemes.
See NGC 6907 and Lenticular galaxy
Light-year
A light-year, alternatively spelled light year (ly or lyr), is a unit of length used to express astronomical distances and is equal to exactly 9,460,730,472,580.8 km (Scientific notation: 9.4607304725808 × 1012 km), which is approximately 5.88 trillion mi.
Luminous infrared galaxy
Luminous infrared galaxies or LIRGs are galaxies with luminosities, the measurement of brightness, above. NGC 6907 and Luminous infrared galaxy are luminous infrared galaxies.
See NGC 6907 and Luminous infrared galaxy
Morphological Catalogue of Galaxies
The Morphological Catalogue of Galaxies (MCG) or Morfologiceskij Katalog Galaktik, is a Russian catalogue of 30,642 galaxies compiled by Boris Vorontsov-Velyaminov and V. P. Arkhipova.
See NGC 6907 and Morphological Catalogue of Galaxies
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 6907 and New General Catalogue are NGC objects.
See NGC 6907 and New General Catalogue
NGC 1097
NGC 1097 (also known as Caldwell 67) is a barred spiral galaxy about 45 million light years away in the constellation Fornax. NGC 6907 and NGC 1097 are barred spiral galaxies, NGC objects and UGCA objects.
Orders of magnitude (length)
The following are examples of orders of magnitude for different lengths.
See NGC 6907 and Orders of magnitude (length)
Parsec
The parsec (symbol: pc) is a unit of length used to measure the large distances to astronomical objects outside the Solar System, approximately equal to or (AU), i.e..
Principal Galaxies Catalogue
The Principal Galaxies Catalogue (PGC) is an astronomical catalog published in 1989 that lists B1950 and J2000 equatorial coordinates and cross-identifications for 73,197 galaxies.
See NGC 6907 and Principal Galaxies Catalogue
Second
The second (symbol: s) is the unit of time in the International System of Units (SI), historically defined as of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each (24 × 60 × 60.
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.
See NGC 6907 and Spiral galaxy
Supernova
A supernova (supernovae or supernovas) is a powerful and luminous explosion of a star.
Tidal force
The tidal force or tide-generating force is a gravitational effect that stretches a body along the line towards and away from the center of mass of another body due to spatial variations in strength in gravitational field from the other body.
Type Ia supernova
A Type Ia supernova (read: "type one-A") is a type of supernova that occurs in binary systems (two stars orbiting one another) in which one of the stars is a white dwarf.
See NGC 6907 and Type Ia supernova
Type Ib and Ic supernovae
Type Ib and Type Ic supernovae are categories of supernovae that are caused by the stellar core collapse of massive stars.
See NGC 6907 and Type Ib and Ic supernovae
Type II supernova
A Type II supernova or SNII (plural: supernovae) results from the rapid collapse and violent explosion of a massive star.
See NGC 6907 and Type II supernova
Uppsala General Catalogue
The Uppsala General Catalogue of Galaxies (UGC) is a catalogue of 12,921 galaxies visible from the northern hemisphere. NGC 6907 and Uppsala General Catalogue are UGCA objects.
See NGC 6907 and Uppsala General Catalogue
William Herschel
Frederick William Herschel (Friedrich Wilhelm Herschel; 15 November 1738 – 25 August 1822) was a German-British astronomer and composer.
