The intensely hot core lights up the departinggas and creates a planetary nebula (given its nameby William Herschel, who thought that the disklikeclouds looked like planets). Planetary nebulas last a fewthousand years, and so are very rare—only about 1,500 areknown in the Milky Way Galaxy. The Cat’s Eye Nebula isone of the most complex. It is about 1,000 years old.Like a flower bursting into bloom, a planetary nebulaunfolds into space. Another swollen red giant has diedand puffed off its outer layers in an expanding cloud thatwill shine for tens of thousands of years. All starswith a mass up to eight times that of the Sun willend their lives in this way, their material spreadout into delicate glowing rings and shells. Thenebula will gradually fade and disappear,but at its heart is a white dwarf—the hot,dense remains of the star’s core that, overbillions of years, will cool and disappear.PLANETARY NEBULASBUTTERFLY NEBULAOne of the most beautiful planetary nebulas is Minkowski2-9, an example of a butterfly nebula. Astronomers believethat the white dwarf at its center is pulling material off alarger companion star, creating a swirling disc of gas anddust. When the red giant blew off its outer layers, the diskdeflected the material into two jets, streaming out at morethan 200 mph (300 km/s).
