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.

Sunshine (Jonathan Edwards song)
"Sunshine" is a country folk song from 1971 by Jonathan Edwards, released as the first single from his debut album Jonathan Edwards. The single reached Billboard #4 and earned a gold record.
"Sunshine" was not originally planned for release, but when an engineer accidentally erased the master of a track called "Please Find Me" near the end of sessions for the album, "Sunshine" was used to fill the hole.
The song was released as a single and first gained popularity on Boston radio, then nationwide, hitting #4 on the Billboard Hot 100 chart on January 15, 1972 and earning a gold record. Here's Edwards' take on its success: "It was just at the time of the Vietnam War and Nixon. It was looking bad out there. That song meant a lot to a lot of people during that time--especially me."

Aurelia
Aurelia (also spelled Aurélia or Aurelija) is a feminine given name from the Latin family name Aurelius, which was derived from aureus meaning "golden". The name began from minor early saints but was given as a name due to its meaning, and not from where it originated. Aurelia may refer to:
Ancient and medieval ages

Aurelia and Blue Moon
Aurelia and Blue Moon are hypothetical examples of a planet and a moon on which extraterrestrial life could evolve. They are the outcome of a collaboration between television company Blue Wave Productions Ltd. and a group of American and British scientists who were collectively commissioned by National Geographic. The team used a combination of accretion theory, climatology, and xenobiology to imagine the most likely locations for extraterrestrial life and most probable evolutionary path such life would take.
The beginning concepts appeared in a two-part television broadcast called Alien Worlds, aired in 2005 in the UK by Channel 4. Channel 4 has also released a DVD of the program. The show was also aired on the National Geographic Channel as Extraterrestrial on Monday, May 30, 2005 and focuses more on the alien life on the two worlds.
The first program in the series focused on Aurelia, a hypothetical Earth-sized extrasolar planet orbiting a red dwarf star in our local area of the Milky Way. The second focuses on a moon called Blue Moon, which orbits an enormous gas giant that is itself orbiting a binary star system.
Aurelia (genus)
Aurelia is a genus of scyphozoan jellyfish, commonly called moon jellies. There are at least 13 species in the genus Aurelia including many that are still not formally described. It has been suggested that Aurelia is the best-studied group of gelatinous zooplankton, with Aurelia aurita the best-studied species in the genus; two other species, Aurelia labiata and Aurelia limbata have also been investigated (studies summarized by Arai). Since most previous studies of Aurelia were done without the benefit of genetic identification, one cannot positively attribute the results of most research to the species named. Species of Aurelia can be found in the Atlantic Ocean, the Arctic Ocean and the Pacific Ocean, and are common to the waters off California, northern China, Japan, Korea, Australia, New Zealand, the Black Sea, Indonesia, the East Coast of the United States as well as Europe.Aurelia undergoes alternation of generations, whereby the sexually-reproducing pelagic medusa stage is either male or female, and the benthic polyp stage reproduces asexually. Meanwhile, life cycle reversal, in which polyps are formed directly from juvenile and sexually mature medusae or their fragments, was also observed in Aurelia sp.1.
