NASA founded a Brown Dwarf

     NASA discovered a Brown Dwarf whose paper was published on 24 May 2017 in the Astrophysics Journal. Castro and four other citizen were the co-author of the paper. There are 117 additional dwarf planets candidates has identified by Planet 9. These planets were orbiting at the fringes of our solar system beyond Pluto.

Scientists said that the dwarf planet was discovered since two decades. These new type of dwarf is an intermediate between a star and a planet. And it can ability for Nuclear fusion reactions They do not energy to maintain their luminosity, so they slowly cool over the years and due to their lower temperature also render them very intrinsically dim.

For many years Kuchner has been fascinated by Infrared images of the whole sky captured by NASA's Wide-field Infrared Survey Explorer (WISE) which was launched in 2009. This telescope was especially designed to image dwarf planets like this, but after its initial mission it was deactivated in 2011. It was then reactivated as NEOWISE, a new mission funded by NEO Observation program.
