Document Summary

Two windows -- one for visible light and another for the radio part of the spectrum, which is why astronomers can base their radio telescopes on earth and still detect the radiation. The greater the energy absorbed, the shorter the absorbed photon"s wavelength. - these patterns allow you to tell what chemical elements are in the star. In the bohr"s model, electrons can have orbits of different sizes: each orbit corresponds to the energy level. Studying starlight reveals the temperature of a star (from its color) Chapter 14: black holes - the end of space and time remaining mass against the force of gravity a. The result is a black hole, in which the matter disappears from contact with the rest of the universe. The formation of a stellar-mass black hole: discovery of pulsars (neutron stars) made it seem more reasonable that black holes could exist.
