Resolution is important for astronomers making observations, since higher resolution allows more details of an object to be clearly discerned. X-ray observations of the Sun allow astronomers to study flares and explosions occurring on its surface. This article introduces a new method of increasing the resolution of X-ray observations of the Sun by using the wave properties of X-rays, which will give higher resolution images of the Sun's explosive surface.
