We report the first (to our knowledge) experimental demonstration of lensless ghost imaging with true thermal light. Although there is no magnification, the method is suitable for all wavelengths and so may find special applications in cases where it is not possible to use lenses, such as with x rays or γ rays. We also numerically show that some magnification may be realized away from the focal plane, but the image will always be somewhat blurred.
