Sunlight

Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light. On Earth, sunlight is filtered through Earth's atmosphere, and is obvious as daylight when the Sun is above the horizon. When the direct solar radiation is not blocked by clouds, it is experienced as sunshine, a combination of bright light and radiant heat. When it is blocked by the clouds or reflects off other objects, it is experienced as diffused light. The World Meteorological Organization uses the term "sunshine duration" to mean the cumulative time during which an area receives direct irradiance from the Sun of at least 120 watts per square meter.

The ultraviolet radiation in sunlight has both positive and negative health effects, as it is both a principal source of vitamin D₃ and a mutagen.

Summary

Researchers may record sunlight using a sunshine recorder, pyranometer, or pyrheliometer.

Sunlight takes about 8.3 minutes to reach Earth from the surface of the Sun. A photon starting at the centre of the Sun and changing direction every time it encounters a charged particle would take between 10,000 and 170,000 years to get to the surface.

Vasco

The name Vasco, currently used as a Portuguese male name, derives from the medieval Iberian name Velasco, which probably has its origins in the Basque country (in Spanish: País Vasco).

Vasco Rossi

Vasco Rossi (born 7 February 1952), also known as Vasco or with the nickname Il Blasco, is an Italian singer-songwriter. During his career, he has published 26 albums (not including unofficial releases) and has written over 250 songs, as well as lyrics for other artists. He calls himself a "provoca(u)tore" (an Italian portmanteau for "provoking author") as throughout his career he has been regularly criticized over his choice of lifestyle and the lyrics in his songs.

Biography

Early life and education

Vasco Rossi was born in Zocca, in the province of Modena (Emilia-Romagna). His father, Carlo Rossi, was a truck-driver, and his mother, Novella, a housewife. It was his mother herself who decided to enroll him in singing school when he was a little boy, a choice that must have seemed rather peculiar within the mentality of a small village in the Apennines like Zocca. Nonetheless, Rossi fell in love with music and at the age of 14 began playing with his first band.

Rossi and his family moved to Bologna, Italy, where he studied accounting in high school. Upon graduating he opened a music club, Punto Club, and enrolled in university at the faculty of Economics and Business. In the meantime he supported himself by working as a DJ and founding, along with friends, one of the first private radio stations in Italy, "Punto Radio", with which he began slowly and timidly showcasing his own songs.
