Why can't we see the sun's corona under normal conditions?
The sun's brightness is overwhelming and blocks it out. It can be viewed with a telescope called a Coronagraph or during a total solar eclipse.
How does the ETC work?
it work sby
Where do Astrobiologists work?
they work for NASA, colleges, universes and national labs
Is an astronauts work inside or outside?
Astronauts have both inside and outside work.
Did Edwin Hubble work with anyone?
did Edwin Hubble work with any one
How do you use coronagraph in a sentence?
"The scientists used a coronagraph to photograph the sun's corona." sorry that sucks lol i tried

The suns is only visable during solar eclipse?
"Corona". This is not entirely correct, because the Sun's corona can be seen at any time using a coronagraph, a special telescope that blocks the light from the Sun itself while allowing the light from the corona to come through.
A device to look at the sun?
a Solar telescope is one, also a Coronagraph which is used to in a sense make an artificial eclipse in the observatory. The Coronagraph was invented in l93l by a French Astronomer. I saw two of them once in a museum in Philadelphia in the seventies, oddly they were in a temporary exhibit with weather instruments, ok, solar energy is part of weather, I am sure. They had telescopes with the necessary light-reduction filter ,opunted on shouder stocks rather like Mannlicher rifles, these were full-length shoulder stocks, the Coronagraph was the (barrel) I seemed to think they had a trigger group also, possiblky these had a camera attachment The astronomer"s name was Bernard Lyot prounounced (Leo) like the Lion constellation. Dop not confuse with chronograph which is a type of watch, Many do confuse the two, Corona meaning Crown, part of the Solar structure normally invisible except during an eclipse. Obvosy there are serious eye-safety concerns here requiring special light-attenuation to bring down the solar light to a safe level. I wish I had more information on this unusual instrument which was aimed directly at the sun with a shoulder stock.l
If the moon was further away would you get a corona on a solar eclipse?
Not with the naked eye, although we have special instruments - the coronagraph - that allow us to see the solar corona at any time. You can only see the solar corona with the naked eye during a total solar eclipse, and the Moon is already too far away to do that at apogee. If the Moon were further away than it is now, you would NEVER see a total solar eclipse.
Which layers of the sun can be seen during a solar eclipse?
The corona of the Sun can only be seen with the naked eye during a total solar eclipse. However, with a special telescope called a coronagraph, you can view the solar corona at any time.During a solar eclipse, you can see the corona as a bright ring. But compared to the brilliance of the Sun itself, the corona is invisibly dim. That's why you can only see it when the Sun itself is hidden behind the Moon.
Why can the sun's corona only be observed during an eclipse?
Actually, the solar corona can be observed at ANY time, if you have the proper equipment. This device, called a coronagraph, creates its own eclipses by blocking the direct light from the Sun and allowing the corona to be observed. The problem is that the Sun is so insanely brilliant that things that are merely "a little bright" are invisible in comparison. When the Moon blocks the direct view of the Sun, then the corona (which is much larger) is finally able to be seen.
Why is corona of the sun is seen during total eclipse?
One of the amazing coincidences in astronomy is that during a total solar eclipse, the disk of the Moon is often JUST THE RIGHT SIZE to hide the Sun itself, while allowing the corona to be visible. If the Moon were much larger or nearer, we wouldn't be able to see the corona without special instruments, and we might not have invented them as soon as we did. Of course, it's not a perfect system; when the Moon is near apogee (farthest distance from the Earth) the disk of the Moon is not large enough to cover the Sun, and we have "annular" eclipses. And with the proper instrument, called a "coronagraph", you can see the Sun's corona any time you like. There are several available for viewing on the web; spaceweather.com often features coronagraph photos. The Sun's corona is bright only when compared to the blackness of space; when the Sun itself is visible, the corona is invisibly dim by comparison. So when the Moon blocks the disk of the Sun itself, or when we artificially block the Sun, we can finally see the corona.
What features are visible during a solar eclipse or with special instruments that cover part of the sun?
The solar corona, the thin sort-of-bright atmosphere of the Sun, was only visible during total solar eclipses. That's because the Sun itself was so much BRIGHTER that the corona was completely invisible except during an eclipse. With a special telescope called the coronagraph developed in 1930, it became possible to block the Sun's direct light and view the corona all the time.
What is the corona of the star and where is it located?
The corona of a star (such as our Sun) is the glowing wispy tenuous gas around the star. It is all around the star. The corona of the Sun is visible during total solar eclipses, when the Sun itself is behind the Moon, but once the Sun comes out from behind the Moon the Sun is so brilliant that the corona is invisibly dim. There's a special type of telescope called a "coronagraph", which blocks the Sun with a metal plate and allows scientists to examine the corona at any time.
Very hot gas of the sun visible only during a total solar eclipse?
The corona of the Sun is not usually visible to the naked eye; even though it is fairly bright, the Sun itself is so MUCH brighter that you cannot see it. Except during a solar eclipse, when the Moon blocks the direct rays of the Sun. But astronomers can see the Sun's corona at any time,by using an instrument called a coronagraph; this device blocks the direct rays and allows astronomers to study the corona. Think of it as an artificial eclipse maker.
How did African slaves get education?
They got their education by secretly learning it if their master didn't allowed because it was illegal. Sometimes, their masters tought the slave even though it was against the law. By secretly learning it, they could learn it off another slave or steal a book and educate themselves.
