The sun's corona is ordinarily not visible (from earth) because though the corona itself is extremely bright, the rest of the sun is even brighter. The sun creates so much light that it makes the corona invisible from earth. The corona however can be seen during a solar eclipse. If you are asking this question than hopefully you already know what a solar eclipse is. If you don' know, a solar eclipse occurs when the Moon passes directly between Earth and the sun, blocking sunlight from Earth. The reason you can see the corona is because the moon though it is much smaller than the sun, looks as if it takes up the the whole sun; that is how it looks like from Earth because of the relative distance between the moon, the sun, and Earth. Since the corona is the most faint layer of the sun, when the rest of the sun is no longer visible (as it is not in a solar eclipse) there is no brighter light that outshines the corona which makes the corona the only visible light coming from the moon and in turn making the corona visible. I do hope this explanation has answered your question and the ones you haven't even asked.
[Caution: Don't EVER look at a solar eclipse without special protection for your eyes. You could cause serious and/or permanent damage to your vision if you do.]
The Sun's corona is actually much dimmer than the Sun itself; we cannot see the corona against the glare of the Sun. Actually, you can see the solar corona at any time by use of a special telescope called a coronagraph. This blocks out the direct rays of the Sun, creating an artificial eclipse.
It can be seen at other times only through a specially designed instrument called a Corongraph. they used to have two of them, both with Mannlicher shoulder stocks, in the Franklin Institute in the Weather station area. Do not confuse with chronograph which is a form of timepiece.
During a solar eclipse, the moon only blocks out the main part of the sun. The corona is visible because the moon is not blocking it.
The main part of the sun is much brighter than the corona. Film, lens and CCDs do not have the dynamic range to process both. Its like thunder masking a thumb snapping.
Even a little solar light overpowers the glow of the corona, which is very hot, but also very thin.
about 5 times a year, during the new moons
Corona the corona is the Sun's atmosphere,extending out several million miles from the Sun's visible face,the photosphere despite its extent,it is exceedingly faint,shining with only one-millionth as much light as the photosphere.For this reason the corona is most easily photographed during a solar eclipse,when the photosphere blocked by the Moon.A capful of gas from the photosphere contains a trillion times more gas particles than a cupful from the corona. Only the Sun's outer layers, collectively referred to as the solar 'atmosphere', can be observed directly. There are distinct regions to the solar atmosphere: the photosphere, the chromosphere, and the corona. These three regions have substantially different properties from each other, with regions of gradual transition between them.
it depends. It can sometimes be a solar eclipse, and other times a lunar eclipse,
During the 100 years of the 20th Century (1901 - 2000), there were 228 solar eclipses and 13 times lunar eclipses.
558 all sollar eclipse ..
the atmosphere of the sun is called the corona the corona is many times hotter the surface of the sun. Astronomers can see the corona with special laboratory equipment, but otherwise it is only visible during a total eclipse.
The corona always emits light, but normally it is hidden by the light of the much brighter photosphere. During a total solar eclipse the moon completely blocks the photosphere, allowing us to see the surrounding corona.

It goes in 9.3 times.
In the USA, The Twilight Saga: Eclipse will be released on June 30, 2010. For other countries, check your local theater for showings and times for The Twilight Saga: Eclipse.
They kissed like 5 times. I would know, i was counting during the movie lol.
A lunar eclipse is where the moon passes behind the Earth. It is only visual during the night when the moon can be seen. Hence, it will always be a full moon. The moon will have an orange-red color, due to the refraction from the sun. The next lunar eclipse will be in December 2010. A solar eclipse is where the moon passes between the Sun and the Earth. During a partial solar eclipse, only parts of the sun are out of view from Earth, but during a total solar eclipse, the sun is fully blocked; however, solar eclipses are rare and can only be seen from certain places during certain times. The next solar eclipse will be in 2012.
You will be fine looking at it during totality, but at other times, when the sun is only partly covered, it can damage your eyes and lead to permanent damage to your vision.
