February 12, 2014
Astronomers know that while large stars can end their lives as violently cataclysmic supernovae, smaller stars end up as planetary nebulae--colorful, glowing clouds of dust and gas. In recent decades, these nebulae, once thought to be mostly spherical, have been observed to often emit powerful, bipolar jets of gas and dust.
