Dying star offers glimpse of our Sun’s future

This planetary nebula is known as Kohoutek 4-55 (or K 4-55). It is one of a series of planetary nebulae that were named after their discoverer, Czech astronomer Luboš Kohoutek. Such a nebula is formed from material in the outer layers of a red giant star that are expelled into interstellar space when the star is in the late stages of its life.
