🐱 Cat’s Eye Nebula! This extraordinary cosmic object is called a planetary nebula, which form when a Sun-like star ejects its outer gaseous layers, creating a bright nebula with amazing shapes. Observations of the Cat’s Eye Nebula suggest that it was created by a star that cast off its mass in a series of pulses at 1,500-year intervals. Each resulting dust shell contains as much mass as all of the planets in our solar system combined…which is still only one percent of our Sun's mass! This nebul

More formally known as Caldwell 15, the Blinking Planetary is, as the name suggests, classified as a planetary nebula. This sort of nebula doesn't have anything to do with planets; however, they appeared like planets in early telescopes, earning them their name. Planetary nebulae are expanding shells of gas cast off from an aging or dying Sun-like star. C15 resi
