It's going to be difficult to tell you more than I know, but I'll give it my best shot.\n\nThe sun is big and bright and hot.  It is a giant fusion reactor creating energy by fusing atoms of matter together.  The energy is transmitted out into space as photons of light.\n\nIt is a medium sized yellow star which began making energy about 4 billion years ago and is estimated to have about 5 billion years left before its fuel begins to run out.

Each and every type of Rays are emitted by the sun whether it is UV rays, Alpha, beta, gamma rays, X- rays, cosmic rays, and many more.

that we can see?  The sun.

because of the distance and variations of the surface temperature of the sun, plus the infrared spectrum within the sun, sun spots appear darker.Photvoltiac activity is contained within or under the suns surface, thereby hidden from our view, but detected via spectrum analyzers

There is an awful lot of info. You are talking about a field to which tens of thousands of people have each dedicated a lifetime of study!  If you are studying for a test, you need to focus on the contents of that particular test.  \n\nA nice site I like that has cursory information on many thing astronomical and space related written for the lay person is the Astronomy Picture of the Day.\n\nhttp://apod.gsfc.nasa.gov\n\nThe archives go back to 1994, with few repeats.

It absorbs light energy from the sun.

How hot is concentrated light, what is the temp of the sun?\n\nWELL WE HAVE A ENERGY SHORTAGE, ONLY AT SUNSET.\n\n I read about Solar collection in power plants like Solar One.  In these plants the where they make molten salt, for heat transfer for running steam generator. At the reciever of Solar One plant or concentrated light point temperature reachest approximately 1,050 Fahrenheit.\n    \n      THIS LINK IS ABOUT YOUR SUN AND THE TEMPS ARE HOT.\n         SO HOW MUCH LIGHT CAN WE CONDENTRATE MORE  \n           DEVELOPMENT IN SOLAR SAILS\n\nhttp://hyperphysics.phy-astr.gsu.edu/hbase/hframe.html \n\n Earth's Sun is a medium-sized star which lies on the main sequence with 90% of the known stars. It has a effective surface temperature is 5780 K, putting it in spectral class G2. Its mass is 1.989 x 1030 kg and its mean radius is 6.96 x 108 meters. The mass of the sun is over 99.8% of the mass of the entire known solar system, leading de Pater and Lissauer to refer lightly to the solar system as "the Sun plus some debris". \n\nThe sun radiates energy at the rate of 3.85 x1026 watts. Just outside the earth's atmosphere solar energy is received, assuming normal incidence, at the rate of 1340 watts per square meter. \n \n\nThe orbit of Earth ranges from 1.47 to 1.52 x 1011 meters from the Sun. The average light travel time to the earth is 8.3 minutes. \n\nThe radius of the sun at 696,000 km is 109 times the Earth's radius. Its surface gravity is 274 m/s2 or 28.0 times that of the Earth. Its mean density is 1410 kg/m3 or 0.255 times the mean density of Earth. \n\nThe composition of the sun is 71% hydrogen, 27.1% helium and less than 2% of all other elements. \n\nThe center temperature is modeled to be 15.5 million K. The Sun is fueled by the proton cycle of nuclear fusion.\n\nEscape velocity = 618 km/s\n\nSO

The electromagnetic spectrum is just a classification of the various types of light. So you are asking whether the sun uses light? Well, it certainly *emits* a lot of light and there is a lot of electromagnetic radiation (i.e. light) inside the sun, but past that, it's not clear what you want.

Like the  filament in a light bulb, stars don't produce the energy themselves.  A massive electric current flowing through space passes through the Sun, heating it up and creating light.  The evidence for this energy is all over the place, but a few things with the Sun that tip us off are:\n\n1. Missing neutrinos \n2. Temperature of the halo-like corona is 300 times that of surface \n3. Rotates faster at equator, faster on surface \n4. Solar wind accelerates upon leaving the Sun \n5. Sunspots reveal cooler interior \n6. Sunspots travel faster than surrounding surface \n7. Sunspot penumbra (interior walls) reveal structured filaments\n\nThere are a lot of other examples among the planets that show us that our solar system is electrified.  The movement of the planets are caused by these massive electric currents coming from the Sun, spinning in the magnetic field created by these electric currents.  The astronomers nowadays always like to talk about magnetic fields, always ignoring the fact that where there are magnetic fields there are electric currents.\n\nhttp://i43.photobucket.com/albums/e397/Bigpappadiaz/magcur.gif\n\nDo some research on the Electric Universe, because the future of astronomy and astrophysics is plasma cosmology.

Yes the Sun is a star.\n\nAnd off topic...\n\nDoes anybody find excessive cutting and pasting a boor??

yes, search yahoo.\nHere's a good one\nhttp://www.solarviews.com/cap/sun/sundiag.htm i think...

Its a array of satellites etc in New Mexico that study the sun, taking pics etc of sun spots and other solar activites.

If u want something easy u can make a rpleca of the solar system. U can by those foam balls and spray paint them. Or u could do an experiment on two plants giving one sunlight and no light to the other. But still feed and water them.

It depends on what you want to see. The sun can be very interesting viewed with the appropriate equipment. For stars and the aurora late night works well, especially in cooler climates as the cold air causes less distortion of the stars. A good site to see is spaceweather.com.
