"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.
遂想起王安石所言：“贫者不得行礼，贵者得行无礼。”——意思是，普通人有心无力，对天下风俗礼仪，即便想认真隆重，也起不了什么作用；而有权有钱人有条件，却恰恰不带头淳化隆厚风习礼俗，反而争相毁弃文雅、蔑视礼仪，甚至不以粗鄙为耻，反以为荣。这是很危险的，王荆公将此列为末世风俗。
