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.

Our Sun is a reasonably average star. Its surface temperature of 9,900 degrees F results in a yellowish light, just as Planck's equations predict. Betelgeuse, a bright star in the constellation of Orion, is much cooler, about 6,900 degrees F, and so even to the naked eye has an easily identified red hue.
