What is the outer most layer of the suns atmosphere?
It is called the Corona, it's made up of a low density of Plasma and it can only be seen during eclipses
Why is the sun visible only during daytime?
Because absence of sunlight is the definition of night.
Which type of eclipse may be visible to all the people on one side of Earth?
A solar eclipse covers a very narrow path on the Earth, so usually not many people get a chance to see one. It doesn't help that the Earth is 75% water, and some solar eclipses never touch land at all. Lunar eclipses happen on the Moon, not on the Earth, so the entire night-side of the Earth can see it. As for how long the eclipse lasts, solar eclipses last longer because the Earth is bigger than the Moon is. However, the path of totality travels quickly over the Earth, and if you're standing on the Earth watching the eclipse, the eclipse will be over - for YOU - quickly, because the Moon's shadow has moved on. If you could be in a supersonic aircraft keeping up with it, you would be able to see that it actually lasts longer, but from one spot on Earth, a solar eclipse comes and goes VERY quickly.
What is an interesting fact about the sun?
It has over 6 layers, one of which is the corona. You can only see the corona during a total solar eclipse.
Why do eclipses not occur more often?
Lunar eclipses are more frequent than solar eclipses. The quick-and-dirty reason for this is because the earth casts a larger shadow than the moon. Lunar eclipses are also quite a bit longer in duration than solar eclipses. Solar eclipses last minutes, and lunar eclipses can last hours.
Which of the suns layers only visible during eclipses?
Chromosphere and corona
Why can you only see an eclipse at night?
Lunar eclipses can only be see at night. Solar eclipses are visible during the day.
What layer of the sun's atmosphere is visible during a total solar eclipse?
The outermost layer of the sun is the corona. Only visible during eclipses, it is a low density cloud of plasma with higher transparency than the inner layers.
Why do solar eclipses occur during the day?
Solar eclipses occur when the moon moves in front of the sun, causing the suns light to be temporarily blocked. Since the sun is only visible from the Earth's surface during the day, this is the only time that a solar eclipse can occur.
What is one way that a lunar exlipse and a solar eclipse are different?
Lunar eclipses are visible only at night, whereas you can only see a solar one during the day.
Are there more solar eclipses or lunar eclipses?
Sometimes there can be more solar eclipses or more lunar eclipses in a given year, but they're pretty even on average. However, because a solar eclipse is only visible along a narrow track on the Earth's surface, whereas a lunar eclipse is visible from anywhere the Moon is visible, it is much more common to SEE a lunar eclipse. ======================================= During the 100 years from 1901 to 2000, there were 228 solar eclipses and 229 lunar ones, for an average rate of about 2.3 of each per year.
Why don't eclipses of the moon occur frequently?
There are generally two lunar eclipses per year. Sometimes the eclipses are only visible in other places on the Earth, and the "penumbral" eclipses generally aren't noticable.
Why is lunar eclipse seen more frequently?
Lunar eclipses and solar eclipses happen EQUALLY often; about two of each kind per year. However, solar eclipses are visible only across a small path on the Earth, while lunar eclipses are visible from the entire nighttime hemisphere of the planet.
What two parts of the suns outer layers are only visible from earth during a solar eclipse?
The Corona-sphere and the Photosphere
Are all parts of the earth affected by eclipses?
Solar eclipses are visible only for a small portion of the Earth's surface where the moon covers the sun. Lunar eclipses in which the Earth's shadow covers the moon are visible for long distances but it's the color of the moon effected by those not the Earth.
What are two types of eclipses?
There are eclipses of the sun (solar), and eclipses of the moon (lunar). At different places on the Earth, each of those may be total or partial. Sometimes only a partial eclipse is visible anywhere.
Can eveyone in the world see every eclipse?
Lunar eclipses are usually visible for anyone who is on the night side of the Earth. Solar eclipses are limited to a very narrow area for only a few minutes.
