"The nebula appears to have distinct regions that capture different phases of its evolution — 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," NASA's blog post reads. The dark line that runs vertically through the nebula, giving it the cranial appearance, could be the result of "an outburst or outflow from the central star, which typically occurs as twin jets burst out in opposite directions." Both Webb's Near-Infrared Camera (NIRCam) and its Mid-Infrared Instrument (MIRI) were used to document the nebula.
