Gas giant

A gas giant is a giant planet composed mainly of hydrogen and helium. Jupiter and Saturn are the Solar System's gas giants. The term "gas giant" was originally synonymous with "giant planet", but in the 1990s it became known that Uranus and Neptune are really a distinct class of giant planet, being composed mainly of heavier volatile substances (which are referred to as 'ices'). For this reason, Uranus and Neptune are now often classified in the separate category of ice giants.

Jupiter and Saturn consist mostly of hydrogen and helium, with heavier elements making up between 3 and 13 percent of the mass. They are thought to consist of an outer layer of molecular hydrogen surrounding a layer of liquid metallic hydrogen, with probably a molten rocky core. The outermost portion of their hydrogen atmosphere is characterized by many layers of visible clouds that are mostly composed of water and ammonia. The layer of metallic hydrogen makes up the bulk of each planet, and is referred to as "metallic" because the very large pressure turns hydrogen into an electrical conductor. The gas giants' cores are thought to consist of heavier elements at such high temperatures (20,000 K) and pressures that their properties are poorly understood.

Giant star

A giant star is a star with substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature. They lie above the main sequence (luminosity class V in the Yerkes spectral classification) on the Hertzsprung–Russell diagram and correspond to luminosity classes II and III. The terms giant and dwarf were coined for stars of quite different luminosity despite similar temperature or spectral type by Ejnar Hertzsprung about 1905.

Giant stars have radii up to a few hundred times the Sun and luminosities between 10 and a few thousand times that of the Sun. Stars still more luminous than giants are referred to as supergiants and hypergiants.

A hot, luminous main-sequence star may also be referred to as a giant, but any main-sequence star is properly called a dwarf no matter how large and luminous it is.

Formation

A star becomes a giant star after all the hydrogen available for fusion at its core has been depleted and, as a result, leaves the main sequence. The behaviour of a post-main-sequence star depends largely on its mass.

Giant (band)

Giant is an American melodic hard rock band that was formed in 1987. The band consisted of founding members Dann Huff (lead vocals & guitar) and Alan Pasqua (keyboard), and had Dann's brother David Huff on drums and Mike Brignardello on bass. The Huff brothers were part of the founding members of the Christian rock band White Heart.

The band scored one hit, the 1990 power ballad "I'll See You In My Dreams", written by Alan Pasqua and Mark Spiro.

Giant disbanded in the early 90s after recording two albums, but resurfaced in 2000 minus Alan Pasqua and released the album III in late 2001.

In December 2009, it was announced by Frontiers Records that they will be releasing Giant's latest album Promise Land in 2010. Writing for the album started in April 2009 and will include Terry Brock (Strangeways, Seventh Key) on lead vocals and John Roth (Winger) on guitars. Dann Huff will not be a part of the band due to his busy schedule but has co-written seven songs and guested on guitar on two. The release dates were February 26, 2010 for Europe and March 9, 2010 for the US.

Gas (musician)

Gas is a music project of Wolfgang Voigt (born 1961), a Cologne, Germany-based electronic musician. Voigt cites his youthful LSD experiences in the Königsforst, a German forest situated near his hometown of Köln, as the inspiration behind his work under the name Gas. He has claimed that the intention of the project is to "bring the forest to the disco, or vice-versa".

Aliases and projects

Voigt is known for his numerous, nearly inexhaustible list of one-off projects and aliases. Of these, his best known is arguably Gas, a project that saw the marriage of ambient music and 4/4 techno.

Other names under which Voigt has released music include, but are not limited to, All, Auftrieb, Brom, C.K. Decker, Centrifugal Force, Crocker, Dextro NRG, Dieter Gorny, Digital, Dom, Doppel, Filter, Freiland, Fuchsbau, Gelb, Grungerman, Kafkatrax, Love Inc., M:I:5, Mike Ink, Mint, Panthel, Popacid, Riss, RX7, Split Inc., Strass, Studio 1, Tal, Vinyl Countdown, W.V., Wassermann, and X-Lvis.

Characteristics

Gas (album)

Gas is the debut album by Wolfgang Voigt's Gas project. It is the second release under the Gas name, preceded only by the Modern EP. It was released on 29 November, 1996 on the Mille Plateaux label. Like all Gas albums, the tracks are untitled. Along with Modern, it is unusual in that the artwork does not share the unifying forest theme common to all other Gas releases.
