Stars..objects..that you may or may not have heard of,are objects,which throughout their lifetimes,shine and exhale heat and light in different parts of the Electromagnetic spectrum.Stars are born out of a Nebula which consists of
97% Hydrogen and 3% Helium[/br] .The particles of the gas pull each other to form larger particles which pull more and more particles together.Ultimately,When these particles have been collected to a ball,the inward pull of gravity and pressure causes the core to reach 15 million degrees C At that point of time,the star begins to shine.Else,the collected particles just remain there as a Brown Dwarf *
