This article was published in Scientific Daily on December 23. It was about the discovery of two brown dwarfs by scientists Alex Wolszczan, Evan Pugh and Penn State. Brown dwarfs are objects in space that lie between the lines of being a star and a planet. This object is dim and difficult to distinguish from low-mass stars in the early stages of the dwarf's life. They are often called failed stars because they begin their lives the same way as normal stars. However, at one point, they simply didn't have enough gathered mass to generate the energy fueled by the fusion of a star. Scientists are certain that brown dwarfs are the missing link between stars and planets, but the formation of dwarfs is still a mystery. Seeing double brown dwarfs near a star is very rare. Seeing a double close to a type K is a first in the scientific world. This star is called BD +20 2457 and is nearing the end of its life. Normally a brown dwarf would be created by star formation or planetary formation. Planets form when the star rotates around and attracts dust and gas from the nebula. Like th...
