The Sun is 1.4 million kilometers (4.643 light-seconds) wide, about 109 times wider than Earth, or four times the Lunar distance, and contains 99.86% of all Solar System mass. The Sun is a G-type main-sequence star that makes up about 99.86% of the mass of the Solar System. [26]
At this average distance, light travels from the Sun to Earth in about 8 minutes, 19 seconds. The energy of this sunlight supports almost all life [b] on Earth by photosynthesis, [13] and drives Earth's climate and weather. [14] As recent as the 19th century, scientists had little knowledge of the Sun's physical composition and source of energy.
The Sun may be said to illuminate, which is a measure of the light within a specific sensitivity range. Many animals (including humans) have a sensitivity range of approximately 400–700 nm, [ 43 ] and given optimal conditions the absorption and scattering by Earth's atmosphere produces illumination that approximates an equal-energy illuminant ...
Fourteen artists lent their voices as background vocals on "All of the Lights" including Rihanna (pictured) who also sang the song's hook. "All of the Lights" was written by Kanye West, Jeff Bhasker, Malik Jones, Warren Trotter, Stacy Ferguson and Terius Nash. [5] [6] Its production was helmed by West himself and co-produced by Bhasker.
Northern lights activity to increase during solar maximum. Electromagnetic activity is increasing as the sun continues to reach the height of its 11-year solar cycle, which NASA said is expected ...
Multiple other interstellar clouds exist in the region within 300 light-years of the Sun, known as the Local Bubble. [262] The latter feature is an hourglass-shaped cavity or superbubble in the interstellar medium roughly 300 light-years across. The bubble is suffused with high-temperature plasma, suggesting that it may be the product of ...
A solar flare is an intense burst of radiation or light on the sun. Solar flares are the most powerful explosions in the solar system — and the biggest ones can have as much energy as a billion ...
The Earth has been hit by a massive eruption from the Sun – which could cause problems for infrastructure but also lead to stunning northern lights on New Year’s Eve. A large blast of energy ...
