Sombrero Galaxy (also known as Messier Object 104, M104 or NGC 4594) is an unbarred spiral galaxy in the constellation Virgo located 31.13 Mpc from Earth.
 The galaxy has a diameter of approximately 15kpc (50,000 light-years), 30% the size of the Milky Way.
 It has a bright nucleus, an unusually large central bulge, and a prominent dust lane in its inclined disk.
 The dark dust lane and the bulge give this galaxy the appearance of a sombrero.
 Astronomers initially thought that the halo was small and light, indicative of a spiral galaxy, but Spitzer found that the halo around the Sombrero Galaxy is larger and more massive than previously thought, indicative of a giant elliptical galaxy.
 The galaxy has an apparent magnitude of +8.0, making it easily visible with amateur telescopes, and it is considered by some authors to be the brightest galaxy within a radius of 10 megaparsecs of the Milky Way.
 Its large bulge, its central supermassive black hole, and its dust lane all attract the attention of professional astronomers.
A vehicle registration plate, also known as a number plate (British English) or a license plate (American English), is a metal or plastic plate attached to a motor vehicle or trailer for official identification purposes.
 All countries require registration plates for road vehicles such as cars, trucks, and motorcycles.
 Whether they are required for other vehicles, such as bicycles, boats, or tractors, may vary by jurisdiction.
 The registration identifier is a numeric or alphanumeric ID that uniquely identifies the vehicle owner within the issuing region's vehicle register.
 In some countries, the identifier is unique within the entire country, while in others it is unique within a state or province.
 Whether the identifier is associated with a vehicle or a person also varies by issuing agency.
Professor Ochanomizu (お茶の水博士 , Ochanomizu-hakase ) is an anime and manga character from the animated series "Astro Boy".
 He is featured in all versions of Astro Boy to date, including the 1980s series, 2003 series, and the film.
 Created by Osamu Tezuka, the character has since appeared in many of his other works.
 He serves as a guardian to Astro, and sometimes also a caring family member.
 He is also known in various English adaptations as Dr. Packadermus J. Elefun, Professor Peabody and Dr. O'Shay.
Percent-encoding, also known as URL encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI) under certain circumstances.
 Although it is known as "URL encoding" it is, in fact, used more generally within the main Uniform Resource Identifier (URI) set, which includes both Uniform Resource Locator (URL) and Uniform Resource Name (URN).
 As such, it is also used in the preparation of data of the codice_1 media type, as is often used in the submission of HTML form data in HTTP requests.
The bibcode (also known as the refcode) is a compact identifier used by several astronomical data systems to uniquely specify literature references.
In physical cosmology, galaxy filaments (subtypes: supercluster complexes, galaxy walls, and galaxy sheets)<ref name="astro-ph/9602090"> Boris V. Komberg, Andrey V. Kravtsov, Vladimir N. Lukash; "The search and investigation of the Large Groups of Quasars" arXiv: ; Bibcode: 1996astro.
ph..2090K ;</ref> are the largest known structures in the universe.
 They are massive, thread-like formations, with a typical length of 50 to 80 megaparsecs "h" (163 to 261 million light-years) that form the boundaries between large voids in the universe.
 Filaments consist of gravitationally bound galaxies.
 Parts wherein many galaxies are very close to one another (in cosmic terms) are called superclusters.
An IATA airport code, also known as an IATA location identifier, IATA station code or simply a location identifier, is a three-letter code designating many airports around the world, defined by the International Air Transport Association (IATA).
 The characters prominently displayed on baggage tags attached at airport check-in desks are an example of a way these codes are used.
The Samsung Galaxy W (i8150), also known as "Wonder", is an Android smartphone that is a smaller-sized variant of the Samsung Galaxy S II.
 The Galaxy W is a less-powerful downgrade compared to the Galaxy S II, with a specification comparable to the larger Galaxy R and a 9.34 cm (3.7 in) WVGA TFT LCD capacitive touchscreen with a resolution of 480x800.
 The phone also features a 5-megapixel still-image camera that is capable of 720p video capture.
 The main differences between the Galaxy W and other variants are its processor (1.4 GHz single core manufactured by Qualcomm), its higher pixel density compared to the Galaxy S II and the Galaxy R, and a slightly different physical design.
ISO 9362 defines a standard format of Business Identifier Codes (also known as SWIFT-BIC, BIC, SWIFT ID or SWIFT code) approved by the International Organization for Standardization (ISO).
 It is a unique identification code for both financial and non-financial institutions.
 The acronym SWIFT stands for the Society for Worldwide Interbank Financial Telecommunication.
 The ISO has designated SWIFT as the BIC registration authority.
 When assigned to a non-financial institution, the code may also be known as a Business Entity Identifier or BEI.
 These codes are used when transferring money between banks, particularly for international wire transfers, and also for the exchange of other messages between banks.
 The codes can sometimes be found on account statements.
In a computer language, a reserved word (also known as a reserved identifier) is a word that cannot be used as an identifier, such as the name of a variable, function, or label – it is "reserved from use".
 This is a syntactic definition, and a reserved word may have no meaning.
