Describe how scientists can determine the structure of the sun without being able to look inside it?

Answer 1

One way is to study the sun is to break up its light with a prism. A rainbow is a spectrum created when sunlight goes through raindrops, which act as little prisms. If we do this with a special device called a spectrograph, we can see that there are thin dark lines throughout the sun's spectrum. Scientists have examined the different elements on earth, so we are able to figure out what kind of gas, say hydrogen, gives rise to which dark lines. It turns out that every element has a unique set of dark lines, like fingerprints. We can use them to figure out what the sun and stars are made of. They also show us how hot the gases are.

Another way is to look and measure how much light is in the blue part of the spectrum, in the yellow, in the red. The hotter something is, the more light it gives off in the blue compared to the red. All these methods show us that the sun's surface is about 10,000 degrees Fahrenheit

Answer 2

Every one of the answers above views the results of the Sun's outer skin, and the results of its hydrogen/helium fusion...BUT there have been different models bouncing around since the fifties when the folks who created the first atomic weapons. I used these to develop a new model, which explains how things occur inside th Sun.
My model is valid ONLY because nobody can look into the Sun's center. It is my expectation that my model will be proved correct (so far, it is the only model which matches all of the astronomical facts, but the model is young - only came out last year).
Sooo, consider going to the website, reading the article, and adding this to the possibilities of how things work.

Answer 3

Putting it crudely, they run the light beam through a telescope into a prism and the different colours of the spectrum show a sort of bar code in certain colours. This barcode shows the makeup of whats inside that star. This was an accidental discovery but has proved to be 100% accurate.

Answer 4

Hi. Spectral emission lines, observation of the surface features, theory as to how to get to the observations.
