Brown dwarf stars. Computer artwork representing what brown dwarfs of different types might look like to a hypothetical interstellar traveller who has flown a spaceship to each one. A brown dwarf is an object which began to accumulate material like a star but which never collected enough for hydrogen nuclear reactions to begin in its core. Y dwarfs are the newest and coldest class of brown dwarfs and were discovered by NASA's Wide-field Infrared Survey Explorer (WISE). Each type is progressively cooler in atmospheric temperature as you move from left to right: A typical L dwarf has a temperature of 1400 degrees Celsius, a T dwarf of 900 degrees Celsius, and a typical Y dwarf (so far identified by WISE) has a temperature of less than about 25 degrees
