A team of researchers has announced the development of a new way to process X-ray data from NASA’s Chandra X-ray Observatory. This technique will improve the clarity, or sharpness, of some Chandra’s images, including the Cassiopeia A supernova remnant. According to a press release from Rikkyo University in Japan, this new method corrects for the differences in focusing power in different parts of Chandra's images, and could “lead to improved measurement accuracy and the discovery of unknown structures.”
