This photo shows the artistic rendering of the black hole LB-1. A Chinese-led research team has discovered a surprisingly huge stellar black hole about 14,000 light-years from Earth -- our "backyard" of the universe -- forcing scientists to re-examine how such black holes form. The team, headed by Liu Jifeng, of the National Astronomical Observatory of the Chinese Academy of Sciences (NAOC), spotted the black hole, which has a mass 70 times greater than the Sun. Researchers named the monster black hole LB-1. (Xinhua)
