Brown dwarfs are often quite rudely called "failed stars". That's too much pressure to put on any object, even though the reason they fail to be stars is the lack of pressure in their core, I want to ask these people though, are you doing a better job of becoming a star? Anyway let's get to topic here. Brown dwarfs are classified as celestial objects between planets and stars. Their mass can range from around 13 times the mass of Jupiter, all the way up to 80 times, however that mass puts them just under the range of stars, as it is not enough for them to forge a dense enough core during their formation to fuse Hydrogen into Helium, and sadly that reaction is what makes a star a star. They can however, in the early ages after their formation, fuse Deuterium.

The greatest hunt ever lead in history, is the hunt for knowledge. A hunt as old as humanity itself. One generation picks up where the previous one left off, what is learned passes from father to son, from master to novice, from teacher to student, and now here we are, standing on the shoulders of those who came before us just like ‘those who came before us’ did. Everything we know today made one hell of a journey to get to us, yet there is so much of it we take for granted. We have all heard as mere children that light is made of photons, matter is made of atoms, and when we smash those atoms very hard, we get nuclear energy out of them. But these facts were proven by science less than a century ago, they were long mysteries finally solved by the very hard work of some very smart people. Let's talk about stars. We know the Sun is a star, and like every other one it's a gigantic ball of flame. But imagine living in the past, a time before Google Images, before scie...
