Stars

All stars start as a NEBULA. Gravity can pull some of the gas and dust in a nebula together. A star is born when the gas and dust from a nebula become so hot that nuclear fusion starts. Once a star has “turned on” it is known as a MAIN SEQUENCE STAR. When a main sequence star begins to run out of hydrogen fuel, the star becomes a RED GIANT or a RED SUPER GIANT.

After a low or medium mass or star has become a red giant the outer parts grow bigger and drift into space, forming a cloud of gas called a PLANETARY NEBULA. The blue-white hot core of the star that is left behind cools and becomes a WHITE DWARF. The white dwarf eventually runs out of fuel and dies as a BLACK DWARF.

A dying red super giant star will explode as a SUPERNOVA. After the star explodes, some of the materials from the core of the star are left behind. A core of 1.5-3 solar masses may form a neutron star. A more massive core greater than 3 solar masses becomes a BLACK HOLES when it dies.
