Sun

The Sun (in Greek: Helios, in Latin: Sol) is the star at the center of the Solar System and is by far the most important source of energy for life on Earth. It is a nearly perfect spherical ball of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process. Its diameter is about 109 times that of Earth, and it has a mass about 330,000 times that of Earth, accounting for about 99.86% of the total mass of the Solar System.About three quarters of the Sun's mass consists of hydrogen; the rest is mostly helium, with much smaller quantities of heavier elements, including oxygen, carbon, neon and iron.

The Sun is a G-type main-sequence star (G2V) based on spectral class and it is informally referred to as a yellow dwarf. It formed approximately 4.567 billion years ago from the gravitational collapse of matter within a region of a large molecular cloud. Most of this matter gathered in the center, whereas the rest flattened into an orbiting disk that became the Solar System. The central mass became increasingly hot and dense, eventually initiating nuclear fusion in its core. It is thought that almost all stars form by this process.

Gun

A gun is a normally tubular weapon or other device designed to discharge projectiles or other material. The projectile may be solid, liquid, gas or energy and may be free, as with bullets and artillery shells, or captive as with Taser probes and whaling harpoons. The means of projection varies according to design but is usually effected by the action of gas pressure, either produced through the rapid combustion of a propellant or compressed and stored by mechanical means, operating on the projectile inside an open-ended tube in the fashion of a piston. The confined gas accelerates the movable projectile down the length of the tube, imparting sufficient velocity to sustain the projectile's travel once the action of the gas ceases at the end of the tube or muzzle. Alternatively, acceleration via electromagnetic field generation may be employed in which case the tube may be dispensed with and a guide rail substituted.

The first devices identified as guns appeared in China around CE 1000. By the 12th century the technology was spreading through the rest of Asia, and into Europe by the 13th century.

Guns N' Roses

Guns N' Roses is an American hard rock band from Los Angeles formed in 1985. The classic lineup, as signed to Geffen Records in 1986, consisted of vocalist Axl Rose, lead guitarist Slash, rhythm guitarist Izzy Stradlin, bassist Duff McKagan, and drummer Steven Adler. The current lineup consists of Rose, Slash, McKagan, Use Your Illusion–era keyboardist Dizzy Reed, guitarist Richard Fortus, drummer Frank Ferrer and keyboardist Chris Pitman. The band has released six studio albums, accumulating sales of more than 100 million records worldwide, including shipments of 45 million in the United States, making Guns N' Roses one of the world's best-selling bands of all time.

Black Hole Sun

"Black Hole Sun" (sometimes referred to in the UK as "Black 'Ol Sun") is a song by the American rock band Soundgarden. Written by frontman Chris Cornell, "Black Hole Sun" was released in 1994 as the third single from the band's fourth studio album Superunknown (1994). It is arguably the band's most recognizable and most popular song, and remains a well known song from the 1990s. The song topped the Billboard Mainstream Rock Tracks chart, where it spent a total of seven weeks at number one. Despite peaking at number two on the Modern Rock Tracks, "Black Hole Sun" still finished as the number-one track of 1994 for that chart. It failed to hit the Billboard Hot 100 chart due to the rules of a physical/commercial release of the single at the time, but it still peaked at number 24 on the Hot 100 Airplay chart and number nine on the Mainstream Top 40 chart. The song was included on Soundgarden's 1997 greatest hits album A-Sides and appeared again on the 2010 compilation album Telephantasm.
