Sunsets
Sunset or sundown is the daily disappearance of the Sun below the western horizon as a result of Earth’s rotation. The time of sunset is defined in astronomy as the moment when the trailing edge of the Sun’s disk disappears below the horizon. The ray path of light from the setting Sun is highly distorted near the horizon because atmospheric refraction, making the sunset appear to occur when the Sun’s disk is already about one diameter below the horizon. Sunset is distinct from dusk, which is the time at which the sky becomes completely dark, which occurs when the Sun is approximately eighteen degrees below the horizon. The period between sunset and dusk is called twilight. Locations north of the Arctic Circle and south of the Antarctic Circle experience no sunset or sunrise at least one day of the year, when the polar day or the polar night persists continuously for 24 hours. Sunset creates unique atmospheric conditions such as the often-intense orange and red colours of the Sun and the surrounding sky. Sunset creates unique atmospheric conditions such as the often-intense orange and red colours of the Sun and the surrounding sky. As a ray of white sunlight travels through the atmosphere to an observer, some of the colours are scattered out of the beam by air molecules and airborne particles, changing the final colour of the beam the viewer sees. Because the shorter wavelength components, such as blue and green, scatter more strongly, these colours are preferentially removed from the beam. The 16th-century astronomer Nicolaus Copernicus was the first to present to the world a detailed and eventually widely accepted mathematical model supporting the premise that the Earth is moving and the Sun actually stays still, despite the impression from our point of view of a moving Sun.
The Studio Tour (also known as The Backlot Tour) is a ride attraction at the Universal Studios Hollywood theme park in California (USA). The Tour is the signature attraction at the park, and goes into a working movie studio, with various film sets on the lot. In recent years, guests have sat in multi-car trams for the duration of the ride. The Tour lasts about 45–50 minutes[1] and is led by a live tour guide who can be seen throughout the tram on video screens. It travels through the Front Lot, Backlot and various attractions, passing sets and props from movies along the way. The tour inspired a smaller but similar version at Universal Studios Florida, which was removed in 1995.
The tour has always been at the heart of Universal. From 1915, when visitors sat on bleachers for 25 cents, to the 1964 introduction of pink and white GlamorTrams, to the current technological sophistication, the behind-thescenes view of a working movie studio has been a large attraction. During the early years of the tram tour (1964–1965) all of the attractions at Universal were reached via the tram. The tour originally departed from the front lot comissary. In 1965, the upper lot studio tour center opened. In 1991, the tram boarding was moved to the lower lot following the construction of the Starway escalator system. In 1996, boarding moved back to the upper lot to make room for Jurassic Park: The Ride.
