Because in a full eclipse the moon is close enough to the earth to block all the sun's disk and the light of this disk does not visually hide the corona. In an annular eclipse the moon is farther from the earth and not all of the sun's disk is blocked so there is enough light escaping around the block to hide the corona. .
The corona.
I'm not exactly sure what you are asking but the sun is visible everyday! Just look up. During a Total Solar eclipse however the outer atmosphere of the sun known as the corona is visible. This is the only time that it can been seen (with the naked eye) from earth.
The bright red halo around the visible surface of the sun is the corona, the sun's upper atmosphere. by Ashley age 9 IT CAN ALSO BE CALLED THE CHROMOSPHERE:) SABRINA AGE 14
'Corona' is a ring of light around the Sun. It is only seem during a solar eclipse. The word 'corona' is adjectival description, from Latin, for 'Crown'. As are the words 'Coronation', and 'Coronet'. However, 'corona' generally refers to stellar light. Earth shine is reflected sunlight from the Earth and on the Moon. At night during a lunar eclipse, the Moon does not completely disappear , but change to a grey/red colour. This is reflected earth-shine. Sunlight is reflected off the Earth to the Moon. It is them reflected back and we see this 'double' reflection. Its a bit like looking at the images of two mirrors facing each other. The reflections go on forever. The reason the colour changes is because red light is longer wavelength than blue light. Longer wavelengths penetrate further than shorter wavelengths.
Earth is bigger than the moon, but that has absolutely nothing to do with the sun's corona.
Because the sun, Earth, and the moon line up in a strait path with the Earth in between. The corona is the earth's shadow on the moon.
Past Earth's orbit
From Earth, the Photosphere is the part visible on the Sun, though the Corona is the top layer of the Sun. We cannot see the Corona because the Photosphere is so bright.
no , but it can be seen during eclipse of the sun
During a solar eclipse.
the corona affects the earth the most
Photosphere, chromosphere, and corona
Because the Sun's photosphere is so much brighter in visible light (most of the light the Sun's corona emits is ultraviolet). It is necessary to block the light from the Sun's photosphere to see the Sun's corona.
the moon is between the earth and the sun
Because in a full eclipse the moon is close enough to the earth to block all the sun's disk and the light of this disk does not visually hide the corona. In an annular eclipse the moon is farther from the earth and not all of the sun's disk is blocked so there is enough light escaping around the block to hide the corona. .
