G♯ (musical note)

G♯ (G-sharp) or Sol Dièse is the ninth semitone of the solfege. In the German pitch nomenclature, it is known as "gis."

It lies a chromatic semitone above G and a diatonic semitone below A, thus being enharmonic to La Bémol or A♭ (A flat).

When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of the G♯ semitone is 415.305 Hz. See pitch (music) for a discussion of historical variations in frequency.

Sol Líneas Aéreas Flight 5428

Sol Líneas Aéreas Flight 5428 was a passenger flight which crashed in Prahuaniyeu, Río Negro Province, Argentina, on 18 May 2011. All 22 aboard died. The aircraft involved, a Saab 340A, was operating Sol Líneas Aéreas' scheduled domestic service from Ingeniero Aeronáutico Ambrosio L.V. Taravella International Airport, Córdoba, to General Enrique Mosconi International Airport, Comodoro Rivadavia, with stopovers at Governor Francisco Gabrielli International Airport, Mendoza, and Presidente Perón International Airport, Neuquén. The crash occurred on the final leg, with the aircraft coming down 25 kilometres (16 mi) south-west of the town of Los Menucos, Río Negro. A preliminary report suggests it was caused by severe icing of the airframe.

The flight crew declared an emergency at 8:50 pm (UTC−03:00). Local people located at around 2 kilometres (1.2 mi) away from the crash site saw an airplane flying extremely low. A few moments later they heard explosions and noticed black smoke coming from the ground, which suggested an accident had occurred. Firefighters arrived at the scene three hours later, finding no survivors. The black box was located the following day near the crash site. and retrieved on 20 May.

Mercury (planet)

Mercury is the smallest planet in the Solar System and the one closest to the Sun, with an orbital period of about 88 Earth days, which is much faster than any other planet in the Solar System. Seen from Earth, it appears to move around its orbit in about 116 days. It has no known natural satellites. It is named after the Roman deity Mercury, the messenger to the gods.

Partly because it has almost no atmosphere to retain heat, Mercury's surface temperature varies diurnally more than any other planet in the Solar System, ranging from 100 K (−173 °C; −280 °F) at night to 700 K (427 °C; 800 °F) during the day in some equatorial regions. The poles are constantly below 180 K (−93 °C; −136 °F). Mercury's axis has the smallest tilt of any of the Solar System's planets (about ¹⁄₃₀ of a degree). However, Mercury's orbital eccentricity is the largest of all known planets in the Solar System. At aphelion, Mercury is about 1.5 times as far from the Sun as it is at perihelion. Mercury's surface is heavily cratered and similar in appearance to the Moon, indicating that it has been geologically inactive for billions of years.

Luna (XM)

Luna is an original XM Satellite Radio music channel, one of the few XM channels that has not had any live personalities. Luna airs Latin Jazz Music and has been described as "The Hottest In Latin Jazz."

The channel was removed from the satellite lineup on April 17, 2006 but remained available online. Luna was removed from XM Radio Online in July 2008. It is now available both online and to all SiriusXM 2.0 branded receivers on channel 530 in the Latin neighborhood.

Moon

The Moon (in Greek: σελήνη Selene, in Latin: Luna) is Earth's only natural satellite. It is one of the largest natural satellites in the Solar System, and, among planetary satellites, the largest relative to the size of the planet it orbits (its primary). It is the second-densest satellite among those whose densities are known (after Jupiter's satellite Io).

The Moon is thought to have formed approximately 4.5 billion years ago, not long after Earth. There are several hypotheses for its origin; the most widely accepted explanation is that the Moon formed from the debris left over after a giant impact between Earth and a Mars-sized body called Theia.

The Moon is in synchronous rotation with Earth, always showing the same face with its near side marked by dark volcanic maria that fill between the bright ancient crustal highlands and the prominent impact craters. It is the second-brightest regularly visible celestial object in Earth's sky after the Sun, as measured by illuminance on Earth's surface. Although it can appear a very bright white, its surface is actually dark, with a reflectance just slightly higher than that of worn asphalt. Its prominence in the sky and its regular cycle of phases have, since ancient times, made the Moon an important cultural influence on language, calendars, art, and mythology.

Luna (TV series)

Luna was a children's science fiction TV comedy show produced by Central Television for the ITV Network in the United Kingdom and which ran for two series in 1983 and 1984. The first series was recorded at the former ATV studios at Elstree, the second at their Nottingham facility.

Premise

Luna was also the name used by the show's central character, played by Patsy Kensit (1st series) and by Jo Wyatt (2nd series). Luna was co-written by Colin Prockter and Colin Bennett; Bennett also acted in it. The show was created and produced by Micky Dolenz, of the pop group The Monkees. 80H was played by Roy Macready, and U2 by Bob Goody.

The show was about the domestic life of an eccentric family group set in the year 2040 - although in the setting, the characters are not in fact biologically related, but assigned to shared living quarters by the bureaucracy. Parts of the setting were decidedly dystopic; in the first episode, Luna is threatened with execution for having lost her citizen's identity card.
