{{w|Diffraction spike|Diffraction spikes}} are visual artifacts that appear to extend from light sources, mostly when viewed through a reflector telescope. In telescopes, they are often caused by the support struts of the secondary mirror in the telescope. They've become especially well known lately because they're quite prominent in images from the {{w|James Webb Space Telescope}}; its bigger spikes are due to the [https://www.sciencefocus.com/space/diffraction-spikes-jwst/ edges of the hexagonal mirror sections], not the struts. | {{w|Diffraction spike|Diffraction spikes}} are visual artifacts that appear to extend from light sources, mostly when viewed through a reflector telescope.
