Estimates say that approximately 10,000 years ago (as we see it) a star (HD59088), much like our own Sun began to die and its outer layers expelled into the surrounding universe by the violent solar winds of the dying star. Though the long bright orange filaments laced throughout the outer shell are not well understood; the outer shell of material ejected into space was done so during the stars red giant phase and that material is now being ionized by the massive dose of ultraviolet radiation released from the now exposed inner layers of the 10th magnitude white dwarf star itself.
