Webb Space Telescope recently snapped this image of PMR 1, the last gasp of a dying star. It resembles a brain in a transparent skull, inspiring its nickname, the “Exposed Cranium” nebula. The nebula appears to have distinct regions that capture different phases of its evolution. There’s an outer shell of gas that was blown off first and consists mostly of hydrogen, and an inner cloud with more structure that contains a mix of different gases. A distinctive dark lane running vertically through the middle of the nebula defines its brain-like look. This lane could be related to an outburst or outflow from the central star, which typically occurs as twin jets burst out in opposite directions. [NASA/ESA/CSA/STScI]
