What part of the Sun is the corona?

corona, outermost region of the Sun's atmosphere, consisting of plasma (hot ionized gas). It has a temperature of approximately two million kelvins and an extremely low density. The corona continually varies in size and shape as it is affected by the Sun's magnetic field.

Four satellites are operated by Viasat: ViaSat-1, WildBlue1, Anik-F2 and ViaSat-2.

How do astronomers study the evolution of the Sun and other stars?

Studying stars that are similar to the Sun at other stages in evolution. We can only observe our Sun at this particular time of its life, but astronomers can see its past and future by looking at similar stars earlier or later in their cycle. These giant stars pulsate and shed huge amounts of matter. How do astronomers detect structure in the chromosphere? How can astronomers detect structure in the chromosphere? Ans: The structure of the chromosphere is studied primarily using filtergrams. Filtergrams are images of the sun taken through a filter that lets in a very narrow wavelength band of light, such as light emitted by the Hydrogen-alpha transition.

Consequently, how do astronomers know what the outer layers of the sun are made of?

How do astronomers know the composition of the outer layers of the Sun? We take an absorption line spectrum of the Sun. These absorption lines tell us what elements are present in the outer layers. How can astronomers detect neutrinos from the Sun? Physicists have directly detected pp neutrinos, demonstrating that about 99 per cent of the power of the Sun is generated by the pp fusion process. Now, physicists using the Borexino detector ? one of the most sensitive neutrino detectors on Earth ? have succeeded in detecting pp neutrinos.


Is mercury inside the Sun's corona?

The moon would break apart during an explosion. Some of the pieces are large and others are small. There were pieces of the moon that moved in different directions. New moons might be created by a weak explosion with larger pieces of debris.

One may also ask why are observations of solar neutrinos important to both astronomers and physicists?

The Sun is the only star close enough to the Earth for us to observe the neutrinos produced by nuclear fusion reactions. It is important to observe the abundant low-energy solar neutrinos in order to test more precisely the theory of stellar evolution. Why is it that neutrinos can tell us about conditions at the core of the sun hint how are they produced and what happens then ?)? Because they travel so fast and interact so rarely with matter, neutrinos pass from the core of the Sun to the surface in only two seconds. If you could detect them, the neutrinos would tell you about the conditions in the Sun's core as it was only 8.5 minutes ago (much more current information than the photons!).
