It’s always a fun day for the space nerds when a NASA team has new images to share from the James Webb Space Telescope. Today’s pair has brains on the brain, with a look at the fittingly named Exposed Cranium Nebula. More officially, this cloud of space dust and debris is known as Nebula PMR 1. The images shared today may capture a moment in the final stages of a star, as well as giving hints as to how the nebula got its brain-like shape.
“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.
