"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.
Something similar is happening right now in science, except Russia is on the opposite side of the story this time. In the early 2010s, a Kazakhstani computer programmer named Alexandra Elbakyan started downloading articles en masse and posting them publicly on a website called SciHub. The publishers sued her, so she’s hiding out in Russia, which protects her from extradition. As you can see in the map below, millions of people now use SciHub to access scientific articles, including lots of people who seem to work at universities:
