The Sun is by far the largest object in the solar system. It contains more than % of the total mass of the Solar System (Jupiter contains most of the rest). Mass : e30 kg. The Sun's outer visible layer is called the photosphere. Because of the high quality instrument, more of the subtle and detail magnetic features can be seen Mean surface temperature : 6,°C. Nicola Yoon. The Sun is also a Star – Ein einziger Tag für die Liebe. Einbandgestaltung von Dominique Falla Aus dem Amerikanischen von Susanne Klein.

Solar flares and coronal-mass ejections tend to occur at sunspot groups. This article is about the star. During sunrise and sunset , sunlight is attenuated because of Rayleigh scattering and Mie scattering from a particularly long passage through Earth's atmosphere,  and the Sun is sometimes faint enough to be viewed comfortably with the naked eye or safely with optics provided there is no risk of bright sunlight suddenly appearing through a break between clouds. In the form of the Sun disc Aten , the Sun had a brief resurgence during the Amarna Period when it again became the preeminent, if not only, divinity for the Pharaoh Akhenaton. Astronomy Cosmology Solar System Mars Jupiter Uranus Moon Space Spaceflight Star X-ray astronomy. The solar interior, from the inside out, is made up of the core, radiative zone and the convective zone. The solar magnetic field extends well beyond the Sun itself. This odd behavior is due to the fact that the Sun is not a solid body like the Earth. The sun has enough nuclear fuel to stay much as it is now for another 5 billion years. One theory among scientists is that the atmosphere of the young Earth contained much larger quantities of greenhouse gases such as carbon dioxide , methane than are present today, which trapped enough heat to compensate for the smaller amount of solar energy reaching it.

How Big Is The Sun? Transition region Coronal hole Coronal loop Coronal mass ejection Prominence Helmet streamer Supra-arcade downflows. Do not assume that it is safe to look at the Sun through a filter, no matter how dark the filter appears to be. Interaction Help About Wikipedia Community portal Recent changes Contact page. Light from the core gets scattered in this zone, so that a single photon often may take a million years to pass through. The theory that the Sun is the center around which the planets orbit was first proposed by the ancient Greek Aristarchus of Samos in the 3rd century BC, and later adopted by Seleucus of Seleucia see Heliocentrism. Worship of the Sun was central to civilizations such as the ancient Egyptians , the Inca of South America and the Aztecs of what is now Mexico. One of the most important solar missions to date has been the Solar and Heliospheric Observatory SOHOwhich was designed to study the solar wind, as well as the sun's outer layers and interior structure. Retrieved 13 July The protostellar Sun's composition is believed to dragon with flowers been The Solar Maximum Mission subsequently acquired thousands of images of the solar corona before re-entering Earth's atmosphere in June Retrieved 24 October After hydrogen fusion in its core has diminished to the point at which it is no longer in hydrostatic equilibriumthe core of the Sun will experience a marked increase in density and temperature www rtl de spiele kostenlos its outer layers expand to eventually become a red giant. At the end of a cycle, the magnetic field rapidly reverses its polarity.

Slowly, this will fade, to enter its final phase as a dim, cool theoretical object sometimes known as a black dwarf. Solar activity Solar astronomy Solar dynamo Eclipse Solar energy Solar observation Solar physics Solar System Solar telescope Solar time Standard solar model Radiation Solar neutrino. This enables stereoscopic imaging of the Sun and solar phenomena, such as coronal mass ejections. To inquire about a licence to reproduce material, visit our Syndication site. Many scientists think the sun and the rest of the solar system formed from a giant, rotating cloud of gas and dust known as the solar nebula. Partial eclipses are visible over a wide area of the Earth but the region from which a total eclipse is visible, called the path of totality, is very narrow, just a few kilometers though it is usually thousands of kilometers long. During early b365 stoke on trent of the optical spectrum of the photosphere, some absorption lines were found that did not correspond to any chemical elements then known on Earth.
