The sun is a huge ball of plasma – ionized gas. What we see in the sky is visible light or photons that are emitted by a very thin outer layer of the sun’s surface. To see inside the sun, photons emitted deep within the sun need to penetrate through the sun’s interior and escape into space, which requires photons of much shorter wavelength than visible light. The field of high energy density HED plasmas creates miniature suns to investigate the conditions that occur inside the interiors of stars and planets. Diagnosing these HED plasmas has the same challenges as observing the sun – visible light tells us only what is occurring at their surfaces. In this video, Prof. Thomas White of the University of Nevada at Reno discusses how intense beams of x-rays (having wavelengths much shorter than visible light) can be used to investigate the interiors of HED plasmas. These measurements reveal how matter behaves under the most extreme of conditions found inside stars and planets.
