NASA的韦伯望远镜揭示星际尘埃和气体的复杂层次

ByGotthew

很久很久以前，一颗大质量恒星的内核发生坍塌，产生的冲击波向外喷发，将恒星撕成碎片。当冲击波到达恒星表面时，它穿透了恒星表面，产生了短暂而强烈的X射线和紫外线脉冲，向周围的太空传播。大约350年后，这个光脉冲到达了星际物质，照亮了星际物质，令其升温，并发出红外光。

A star field appears that has several nebulas. Toward the upper left is a angularly small supernova remnant colored blue, while dominating the lower right is a large supernova remnant in both red and blue. Please see the explanation for more detailed information.
星空中出现了几个星云。在左上方，可以看到一个呈蓝色的角状小型超新星遗迹，而右下方则占据主导位置的是一个大型超新星遗迹，呈现出红色和蓝色的色彩。有关更多详细信息，请参阅说明。

NASA的詹姆斯·韦伯太空望远镜在最近观测到的一颗超新星的位置发现了中子星辐射的最佳证据。这颗被称为SN 1987A的超新星是一颗核心坍缩超新星，这意味着其核心被压缩的残骸形成了一颗中子星或一个黑洞。

2023年10月11日 NGC 1097: Spiral Galaxy with Supernova Image Data: Telescope Live (Chile); Image Processing & Copyright: Bernard Miller Explanation: What’s happening in the lower arm of this spiral galaxy? A supernova. Last month, supernova SN 2023rve was discovered with UAE‘s Al-Khatim Observatory and later found to be consistent with the death explosion of a massive star, possibly leaving behind a black hole. Spiral galaxy NGC 1097 is a relatively close 45 million light years away and visible with a small telescope toward the southern constellation of the Furnace (Fornax). The galaxy is notable not only for its picturesque spiral arms, but also for faint jets consistent with ancient star streams left over from a galactic collision — possibly with the small galaxy seen between its…
