Explanation: Scientists around the world have been trying for decades to recreate the unfathomable power of the sun here on Earth, and a team in China has managed to best our local star. Not for very long, though. The team operating the Experimental Advanced Superconducting Tokamak (EAST) managed to heat the reactor’s internal plasma to 100 million degrees Celsius (212 million Fahrenheit). That’s six times hotter than the sun, but it doesn’t have any net power generation. In stars, hydrogen fuses into helium, and eventually into heavier elements. The fusion process releases large amounts of energy, and the byproducts of fusion aren’t radioactive. The only nuclear power we’ve managed to utilize on Earth is fission, which requires dangerous radioactive materials and comes with the risk of a reactor meltdown.
