	Sun - Wikipedia, the free encyclopedia
		The Sun's radius is measured from its center to the edge of the photosphere.
		The optical surface of the Sun (the photosphere) is known to have a temperature of approximately 6,000 K.
		Among the proposals were that the Sun extracted its energy from friction of its gas masses, or that its energy was derived from gravitational potential energy released as it continuously contracted.

	The Sun (newspaper) - Wikipedia, the free encyclopedia
		The Sun is a tabloid daily newspaper published in the United Kingdom and the Republic of Ireland with the highest circulation of any daily English-language newspaper in the world, standing at 3,154,881 copies daily in early 2006 [1], (compared to USA Today, the best-selling US newspaper at 2,281,831 [2]).
		The Sun is known in Cockney rhyming slang as The Currant Bun [3].
		The Sun's ultra-patriotism has, however, outgrown the racism some claim it came close to embracing in the 1970s and 1980s — the nadir was its coverage of the Broadwater Farm riot of 1985 — perhaps because Murdoch and his editors have realised that it needs to appeal to ethnic minority readers to sell its paper.

	The Sun
		Earth's Sun is a medium-sized star which lies on the main sequence with 90% of the known stars.
		The granules are described as convection cells which transport heat from the interior of the Sun to the surface.
		The sun is 7.7 kpc or 25,000 light years from the center of the galaxy and orbits the galaxy in about 200 million years.

	The Sun
		For many years it was thought that their magnetism, unlike the Earth's, originates fairly close to the surface, from an interplay between the uneven rotation period of the Sun (which increases by more than 2 days as one moves closer to the poles) and the constant churning of hot gas near the Sun's surface.
		Pictures taken of the Sun in such filtered light show much more detail than pictures taken in plain sunlight, and contain additional information: for instance, the magnetic nature of sunspots was found by observing them in spectral lines sensitive to magnetic fields.
		When the Sun is observed in the light of such lines, a sudden brightening is now and then seen near sunspots, at times expanding tens of thousands of kilometers in a matter of minutes.

	Howstuffworks "How the Sun Works"
		The sun warms our planet every day, provides the light by which we see and is absolutely necessary for life on Earth.
		Officially, the sun is classified as a G2 type star based on its temperature and the wavelengths or spectrum of light that it emits.
		The sun is an "average" star, merely one of billions of stars that orbit the center of our galaxy.

		Solar energy is transformed by plants into chemical energy, the first step in the food chain for all living things.
		Magnetic studies of the sun show that these are also regions of very high magnetic fields, up to 1000 times stronger than the regular magnetic field.
		During a flare high energy particles are ejected into the corona, heating regions to temperatures in excess of 5 million K. A flare may release an amount of energy equivalent to 100 million "hydrogen" (fusion) bombs.

	The Sun - Introduction
		The photosphere is slightly different from one place on the Sun to another, but in general is has a pressure about a few hundredths of the sea-level pressure on Earth, a density of about a ten-thousandth of the Earth's sea-level atmospheric density, and a temperature in the range 4500-6000 Kelvin.
		The chromosphere merges into the outermost region of the Sun's atmosphere, the corona.
		Because of this high temperature, the bulk of the radiation from the corona is emitted at ultraviolet and X-ray wavelengths.

		The Sun is 150 million kilometers (93 million miles) away from the Earth (this distance varies slightly throughout the year, because the Earth's orbit is an ellipse and not a perfect circle).
		The Sun is neither a solid nor a gas but is actually plasma.
		All of the energy that we detect as light and heat originates in nuclear reactions deep inside the Sun's high-temperature "core." This core extends about one quarter of the way from the center of Sun to its surface where the temperature is around 15 million Kelvin (K) (or 27 million degrees Fahrenheit (F)).

	(S-6) Seeing the Sun in a New Light
		The best-known early observations of the Sun from space were the ones made in 1973 from the space station Skylab.
		Even earlier, around the turn of the century, series of moderate magnetic storms were observed which tended to recur at 27-day intervals, prevalent not near the peak of the sunspot cycle but, perversely, near its minimum.
		Located on the Earth's orbit but 60° ahead and behind it (at the L4 and L5 Lagrangian points of the Earth-Sun system), the cameras on these spacecraft will be able to observe CMEs heading for Earth and even (because of their different vantage points) obtain some information about their 3-dimensional structure.

		However, we have known since the 1940's that the Sun is, in fact, a very strong X-ray emitter.
		The 12 X-ray images of the Sun's atmosphere seen here, obtained between 1991 and 1995 at 90 day increments, provide a dramatic view of how the corona changes during the waning part of the solar cycle.
		The Sun's atmosphere, at millions of degrees, is hot enough to emit X-rays, while the much cooler surface of the Sun is not.

		Electric currents are closely tied with magnetic fields on the Sun and are a key to understanding what goes on both below and above the visible surface of the Sun.The Imaging Vector Magnetograph measures the circular and linear polarization of the Zeeman components of a neutral iron absorption line in the spectrum of the Sun.
		By extrapolating the magnetic field and current data at the Sun's surface, however, it is possible to calculate the magnetic fields in the corona and relate these to the structure, temperatures, pressures, and other physical properties of the corona observed in the spacecraft images.
		The strength of her research is to use the large amount of spacecraft data obtained in the last 8 years by Yohkoh and the last 5 years by SOHO.
