Life of a Star

Journey of a Star There are more than 200 00,000,000,00, Nebula Z000,000,000,000 stars A star is a luminous globe of gas producing its own A cloud of dust and gas. Nebulae are the heat and light by nuclear reactions (nuclear birthplaces of stars. There are different types fusion).The life of the star is unique and extremely Red Dwarf long. This shows various stages in the life of a star of nebula. Convective envelope Cool, faint and small stars before its light reaches us.
