Milky Way could have up to 100 billion 'failed stars': Study
In a survey of brown dwarfs, objects which 'failed' to generate enough hydrogen fusion to become a star, astronomers estimate Milky Way galaxy could have 25-100 billion such bodies. Brown dwarfs are faint objects and therefore difficult to observe. Most of those detected are located in relatively small star-forming regions, and their number can be an underestimate, researchers added.
