German physicist Wilhelm Röntgen is usually credited as the discoverer of X-rays in 1895, because he was the first to systematically study them, though he is not the first to have observed their effects. He is also the one who gave them the name "X-rays" (signifying an unknown quantity) though many others referred to these.

Our Sun's radiation peaks in the visual range, but the Sun's corona is much hotter and radiates mostly x-rays. To study the corona, scientists use data collected by x -ray detectors on satellites in orbit around the Earth. Japan's Hinode spacecraft produced these x-ray images of the Sun that allow scientists to see and record.

Abstract. Structural studies of viruses were reviewed in 1967 by Finch and Holmes (1967) and in 1972 by Finch. Those studies were based on the two available techniques: electron microscopy and X-rays. The use of X-ray diffraction to investigate virus structures from single crystals was just beginning, and although high.
