蟹状星云被编目为M1，是查尔斯·梅西耶在18世纪著名的非彗星清单上的第一个物体。事实上，蟹状星云现在被认为是超新星遗迹，是天文学家在1054年目睹的一颗大质量恒星死亡爆炸的碎片。这张清晰的图像来自詹姆斯韦伯太空望远镜的NIRCam（近红外相机）和MIRI（中红外仪器），在红外光下探索了怪异的辉光和仍然在膨胀的星际碎片云的碎片链。蟹状脉冲星是现代天文学家所知的最奇特的天体之一，它是一颗每秒旋转30次的中子星，在星云中心附近可以看到一个亮点。就像宇宙发电机一样，这个坍缩的恒星核心残骸为蟹状星云在电磁波谱上的发射提供了动力。蟹状星云的跨度约为12光年，距离强大的金牛座仅6500光年。相册：月食金星：选定的图像发送到APOD

The Crab Nebula is cataloged as M1, the first object on Charles Messier's famous 18th century list of things which are not comets. In fact, the Crab is now known to be a supernova remnant, debris from the death explosion of a massive star witnessed by astronomers in the year 1054. This sharp image from the James Webb Space Telescope’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) explores the eerie glow and fragmented strands of the still expanding cloud of interstellar debris in infrared light. One of the most exotic objects known to modern astronomers, the Crab Pulsar, a neutron star spinning 30 times a second, is visible as a bright spot near the nebula's center. Like a cosmic dynamo, this collapsed remnant of the stellar core powers the Crab's emission across the electromagnetic spectrum. Spanning about 12 light-years, the Crab Nebula is a mere 6,500 light-years away in the head-strong constellation Taurus. Album: Moon Eclipses Venus: Selected images sent in to APOD
