Did You Know: Diffraction Spikes
$A cropped image of Herbig-Haro 46/47 takes up the majority of the screen. A large, blue-white star with eight diffraction spikes is in the center of the frame, against the dark background of space. Smaller blue-white and yellow points of light, and a red blob-like object, surround the large star. Text at right reads “Did you know? The spikes around bright stars result from certain telescope designs.”$
