The Voyage of the Beagle by Darwin, Charles View in context. The theory is something like this: Space is pervaded by luminiferous ether, which is a material thing--as much a substance as air or water, though almost infinitely more attenuated. Present At A Hanging And Other Ghost Stories by Bierce, Ambrose View in context.
Stars all seem to be made up of the same elements that are found on Earth, even though they can be different sizes, temperatures, and ages. Our Sun is an average-size star, maybe a little smaller than most stars. Stars the size of our Sun are known as Dwarf Stars.The largest stars can be 10 times larger across then the Sun. These are called Giant or SuperGiant stars.The very smallest stars are not much bigger than the planet Jupiter.tars all seem to be made up of the same elements that are found on Earth, even though they can be different sizes, temperatures, and ages.

The sun has a diameter of 865,000 miles or 1.39 million kilometers. Its diameter is 109 times the diameter of earth. Despite its seemingly huge size in comparison to earth, the sun is actually considered a small star and is classified as a yellow dwarf. The sun is mainly composed of hydrogen and helium.n about eight billion years it is estimated that the sun's radius (and consequently its diameter) will increase greatly due to the large amount of heat that the sun produces. This increase in heat will also change the sun's intensity by 10%, and will most likely have a very disastrous impact on Earth.
