If no star filter was used then it's most likely caused by using a reasonably high fstop. As the aperture closes up, the blades of the aperture mech form a star shape pattern of sorts and starbursts can be created.

I didn't know that, how cool! Thanks You MA!

The cool thing is ... different lens have slightly different aperture mechs so the stars can be different lens to lens.

I believe its the number of blades that affects the stars. I think an even number of blades will result in an equal number of points, and with odd blades the number of points will equal double the number of blades.

Very interesting. Thanks for the info.
