China builds 'artificial sun' 6 times hotter than Sun's core
Scientists at a Chinese institute on Tuesday announced that their nuclear fusion reactor dubbed 'artificial sun' reached 100 millionÂ°C, the temperature required to carry out fusion on Earth. The record-high temperature is six times the temperature of Sun's core of 15 millionÂ°C. The reactor is designed to mimic processes occurring at the Sun to turn hydrogen into cost-effective clean energy.
