Giant

Introduction
Star comes in a variety of different types. Not every Star is like The Sun, some are smaller and some are Giants. These Giants are legendary due to the unimaginable size they encompass. These Juggernaut Stars make our Sun look like a Rookie. There are even bigger Stars that are called Supergiants. Today though, we shall just discuss Giants.
Red Giant
Red Giants are gigantic, towering over and even over encompassing our own star, The Sun. These Stars are hot as hell! Red Giants have an average temperature of 5000 Kelvin, 4727 degrees Celsius or 8540 degrees Fahrenheit! Forget about getting a sunburn from this star, thou shalt receive a sun melt instead if not a sun vanish. This star however is in its late-stages of life. This star is about to die either becoming a Blue Giant than a Neutron Star, A Supernova than a Neutron Star, or a Planetary Nebula than a White dwarf. One day, our own Sun will become a Red Giant. This Star continues to expand, consuming anything in its path until one of the previously mentioned outcomes occur. This all happens because The Star's supply of Hydrogen atoms in the core have run out. This begins the imperial-like expansion of the star. This causes the star to become brighter due to its larger size than before. 3 famous Red Giants are Alpha Tauri, Alpha Bootis & Gamma Crucis. 
Blue Giant
Blue Giants are rare as far as is known in Today's World. Blue Giants are Luminous and sizzling. Blue Giants however are not really a type of star as so much as a stage of a star.  Blue Giants are evolved stars that have extensively lost its supply of hydrogen within its core. Eventually it will become a Red Giant and continues its path to death. An Example of a Blue Giant is  The Blue Giant, Alcyone.
Conclusion
Whether a Blue Giant or Red Giant there are bigger stars out there in space than The Sun. We once thought that The Sun was the big boss in The Universe but that theory was squished overtime and now we know it isn't even close to being the biggest baddest star. This is a good lesson for us to understand for ourselves. That we should be humble and not believe we are the best in the world at a particular thing. The Old saying goes, that there is always someone bigger and tougher than thou art. This seems to be an universal truth that applies to more than just us humans. We should strive to be better versions of ourselves and not become static in our progress thinking that we are the best in the world; for eventually, voluntarily or involuntarily, we will be humbled and put in our place. Keep moving and getting better each and everyday and become the best version of yourself that thou can be. Do this, and thou shalt Thrive!
