Simeis 147: The Spaghetti Nebula Supernova Remnant
Image Credit & Copyright: Saverio Ferretti
Explanation: Its popular nickname is the Spaghetti Nebula. Officially cataloged as Simeis 147 and Sharpless 2-240, it is easy to get lost following the looping and twisting filaments of this intricate supernova remnant. Seen toward the boundary of the constellations of the Bull (Taurus) and the Charioteer (Auriga), the impressive gas structure covers nearly 3 degrees on the sky, equivalent to 6 full moons. That’s about 150 light-years at the stellar debris cloud’s estimated distance of 3,000 light-years. The supernova remnant has an estimated age of about 40,000 years, meaning light from this powerful stellar explosion first reached the Earth when woolly mammoths roamed free. Besides the expanding remnant, this cosmic catastrophe left behind a pulsar, a fast-spinning neutron star that is the remnant of the original star’s core. The featured image was captured last month from Forca Canapine, Italy.

Simeis 147: 意大利面星云超新星残骸
影像提供与版权: Saverio Ferretti
说明: 这个天体的昵称是「意大利面星云」。它的正式名称是Simeis 147和Sharpless 2-240。在这个复杂的超新星遗迹中，顺着那些回圈和扭曲的丝状结构，很容易让人迷失方向。这片壮观的气体结构位于金牛 座和御夫座的交界处方向。这个壮观的气体结构在天球上覆盖了近3度，相当于6个满月的大小。这片星际残骸云的估计距离为3,000光年，推算残骸云的大小约为150光年。这个超新星遗迹的估计年龄约为40,000年，这意味着这次强大的恒星爆炸光芒首次到达地球时，长毛象仍在地球上自由漫步。除了不断扩张的残骸外，这场宇宙灾难还留下了一颗脉冲星，一颗快速旋转的中子星，是原恒星核心的残余。这张主题影像是上个月在意大利的卡纳皮内山口（Forca Canapine）所拍摄。
