Four composite images of two galaxies, a nebula, and a star cluster have been released featuring data combined from NASA's Chandra X-ray Observatory and James Webb Space Telescope. Each image combines Chandra's X-ray data with infrared data from previously released Webb images, both of which are invisible to the unaided eye. Data from NASA's Hubble Space Telescope (optical light) and retired Spitzer Space Telescope (infrared), plus the European Space Agency's XMM-Newton (X-ray) and the European Southern Observatory's New Technology Telescope (optical) is also used. The details within the images are made visible by mapping the data to colors that humans can perceive.
