中文翻譯:
在遙遠的宇宙中，有一個叫做Exposed Cranium Nebula的星雲，因為它看起來像一個人類的腦袋，所以得到了這個有趣的名字。這個星雲的形成依然是一個謎。有一些科學家認為，這是圍繞著一顆白矮星的行星星雲。當它的母恆星，也就是一顆像太陽一樣的恆星，耗盡了能量並縮小後，外層的氣體就被拋棄了。還有一些科學家則認為，中間的星星可能是一顆更為龐大的Wolf-Rayet恆星，它正在快速噴出氣體和塵埃，形成激烈的星際風。這個星雲有著迷人的深色中央分隔和細薄的外層氣體。這幅圖片是用Webb太空望遠鏡在中紅外光下拍攝的，還有一張滾動顯示的圖片是近紅外光拍攝的。未來的觀測可能會告訴我們，這個聰明的系統會不會靜靜地消失，或者在很多年後，突然在天空中爆發成強大的超新星！
原文:
What’s going on inside the head of this nebula? Dubbed the Exposed Cranium Nebula for its similarity to the human brain, what created the nebula remains a mystery. One thought is that the Cranium Nebula, also known as PMR 1, is a planetary nebula surrounding a white dwarf star. In this mode, the outer atmosphere was expelled when the original Sun-like star ran out of central nuclear fuel and contracted. A competing thought is that the central star is much more massive, possibly a Wolf-Rayet star, that is ejecting gas and dust via turbulent stellar winds. Adding to the intrigue is the dark vertical central division and the thin outer gaseous shell. The featured image was taken by the Webb Space Telescope in mid- infrared light, while a second image, included as a rollover, is in near-infrared. Future observations may reveal if this brainy system will quietly just fade from view or, many years from now, suddenly erupt in a powerful supernova.
