A Chandra observation revealed X-rays produced by TWA 5B (faint upper source), a brown dwarf orbiting a young binary star system known as TWA 5A (bright lower source). The star system is 180 light years from the Earth and a member of a group of about a dozen young stars in the constellation Hydra. The brown dwarf orbits the binary star system at a distance about 2.75 times that of Pluto’s orbit around the Sun.
