Stars with a mass of less than 8 solar masses end their lives as planetary nebulae, structures of ionized gas thrown off by the star and heated by the stellar core. Planetary nebulae are often bipolar in shape or contain complex morphological features such as rings or spirals.

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have mapped the stellar winds blowing out from red giant stars and found that their stellar winds have distinct non-spherical geometries with morphological similarities to planetary nebulae.
