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 is a G-type main-sequence star that comprises about 99.86% of the mass of the Solar System. The Sun has an absolute magnitude of +4.83, estimated to be brighter than about 85% of the stars in the Milky Way, most of which are red dwarfs. The Sun is a Population I, or heavy-element-rich, star.n the Sun's outer layer, from its surface to approximately 200,000 km below (70% of the solar radius from the center), the temperature is lower than in the radiative zone and heavier atoms are not fully ionized. As a result, radiative heat transport is less effective.
