Sky Uno (English: Sky One) is an Italian entertainment television channel, based on the defunct reality television channel SKY Vivo, both owned and broadcast by Sky Italia.

During the night it broadcasts the Late Show with David Letterman, which was previously aired on RaiSat Extra. The program is replayed twice the day after.

The channel broadcasts in high-definition from 20 October 2011.

The sky, also known as the celestial dome, commonly refers to everything that lies a certain distance above the surface of Earth, including the atmosphere and the rest of outer space. In the field of astronomy, the sky is also called the celestial sphere. This is an imaginary dome where the sun, stars, planets, and the moon are seen to be traveling. The celestial sphere is divided into regions called constellations. Usually, the term sky is used from the point of view of the Earth's surface. However, the exact meaning of the term can vary; in some cases, the sky is defined as only the denser portions of the atmosphere, for example.

During daylight, the sky appears to be blue because air scatters blue sunlight more than it scatters red. At night, the sky appears to be a mostly dark surface or region scattered with stars. During the day, the Sun can be seen in the sky, unless obscured by clouds. In the night sky (and to some extent during the day) the moon, planets and stars are visible in the sky. Some of the natural phenomena seen in the sky are clouds, rainbows, and aurorae. Lightning and precipitation can also be seen in the sky during storms. Birds, insects, aircraft, and kites are often considered to fly in the sky. As a result of human activities, smog during the day and light pollution during the night are often seen above large cities.

Gabriel Contino, Gabriel o Pensador (Portuguese for Gabriel the Thinker), (born in Rio de Janeiro on March 4, 1974) is a Brazilian rapper.

Coming from a unique background among Brazilian rappers, Gabriel, the son of a well known journalist in Brazil, hit fame in 1992 with the song "Tô Feliz (Matei o Presidente)" ("I'm happy, I've killed the president") the debut single from his first and eponymous album. This song was written in protest of President Fernando Collor de Mello and his corrupt administration. Interestingly, Gabriel's mother was Collor's press secretary. The same album also yielded other hits, including "Lôrabúrra" ("Dumb Blonde", shortened) and "Retrato de um Playboy" ("Portrait of a Playboy"), bringing hip hop mainstream attention in Brazil by catering to the middle class. Although rapping about everyday life, Gabriel also found time to talk about social injustices with his fourth single, "O Resto do Mundo" ("The Leftovers of the World"), a more downbeat track about homeless life, with a purposefully depressive melody and flow. Gabriel was "notorious for his biting attacks on some of the major ills of Brazilian society: poverty, racism, violence."

Alan Parsons (born 20 December 1948) is a British audio engineer, musician, and record producer. He was involved with the production of several significant albums, including The Beatles' Abbey Road and Let It Be, as well as Pink Floyd's The Dark Side of the Moon for which Pink Floyd credit him as an important contributor. Parsons' own group, The Alan Parsons Project, as well as his subsequent solo recordings, have also been successful commercially.

In October 1967, at age 18, Parsons went to work as an assistant engineer at Abbey Road Studios, where he earned his first credit on the LP Abbey Road. He became a regular there, engineering such projects as Paul McCartney's Wild Life and Red Rose Speedway, five albums by The Hollies, and Pink Floyd’s The Dark Side of the Moon, for which he received his first Grammy Award nomination. He was known for doing more than what would normally be considered the scope of a recording engineer’s duties.^{[citation needed]}He considered himself to be a recording director, likening his contribution to recordings to what Stanley Kubrick contributed to film.^{[citation needed]} This is apparent in his work with Al Stewart's "Year of the Cat", where Parsons added the saxophone part and transformed the original folk concept into the jazz-influenced ballad that put Al Stewart onto the charts.^{[citation needed]} It is also heard in Parsons' influence on the Hollies' "He Ain't Heavy, He's My Brother" and "The Air That I Breathe", sharp departures from their popular 1960s hits "Stay", "Just One Look", "Stop! Stop! Stop!" or "Bus Stop".^{[citation needed]} Parsons was also known to have swapped shifts during the engineering of The Dark Side of the Moon so he could work entirely on the project.^{[citation needed]}
