Way Galaxy, the solar system, the sun, and the
universe.
= Milky Way Galaxy

= Sun
= Universe
main sequence star—depends upon their original mass. Most stars with masses similar to the sun spend billions of years as a main sequence star and eventually expand ot become ared giant. As hte botom part of Figure 3-5 shows, these stars use up most of their nuclear fuel and collapse to form awhite dwarf, and then slowly "die" becoming ablack dwarf. This process may take many billions of years, and some stars created soon after the Bgi Bang may still exist.
The evolution of stars with an original mass greater than one and a half times the mass of the sun is substantially different. These stars exist for
giants after spending time as a large main sequence star. They eventually mucosmaelr pana waced art. Tyhe ear ysl cel hat oyr neuotnsnac exist, and a neutron star is formed. When even more massive stars colapse, the density si os great that it creates an extreme gravity field that allows no visible light or any other form of energy ot escape, and a black hole is formed.
