CIFS' Royal Society Summer Science exhibit
Energy from the nuclear fusion reactions which power stars is turned into electromagnetic radiation (a form of light) in the heart of the Sun. There is no way to directly see this light, and previously we could only indirectly work out how it moves through the Sun, deep under the surface. By recreating the conditions inside the Sun in a laboratory, we can directly find out how the radiation carries the energy to the surface.
This isn’t the only stellar application of big lasers; the US National Ignition Facility is using lasers to go a step further and recreate the way that stars make energy through fusion reactions. Fusion promises to be an abundant, clean, and green source of energy. The goal is to produce more energy than the lasers use. It’s a huge challenge, but recent promising results from this experiment mean that there is hope that star power on Earth will become a reality.
