In many photos of star fields, there frequently are groups of stars appearing as some portion of a circle. Often as if viewed from some oblique angle. The "circle of stars" is usually an incomplete circle and often distorted. In some photos (most of what I refer to is contained in the "Astronomy" magazine), several can be seen. Is this the result of supernovas occurring in the distant past? Thanks for your answer!
