NASA have founded 14 coldest stars it had ever recorded , which they name as “brown dwarf” . and coldest of them is Y- dwarf . Y-dwarf is cooler them human body. Basically Brown dwarf are name as “failed stars” by scientist because due to their low density of star it stop it from fusing the atoms in the core which stop them burn with enduring heat like other star for example sun, which will be burn for at least a few billion years.
Why brown dwarf are know as failed stars because they are burning from very extended of time, now they are expired or they cool or fade. Brown dwarf cannot be seen visible light telescope. So scientist made satellite telescope which is know as Wide-field Infrared Survey Explorer or in short WISE.
Amazing thing about Y dwarf is that it is found near in our solar system, Scientist predicted that more failed stars like Y-dwarf can be in our solar light years away with approximately 80 degree Fahrenheit temperature like Y-Dwarfs.
