... 2001 April 15 . Diffraction Spikes: When Stars Look Like Crosses . ... Light scatters away from the original destination point ending up elsewhere and appearing as " diffraction spikes ." These annoying spikes steal precious light from the central image and hide light from fainter, more interesting stars. Above , astronomers are more interested in the half-circled point near the image center, than the cool-looking diffraction spikes from the bright star at the bottom. ... About APOD | ...
