An image shows a cluster of galaxies with unusual arcs. The arcs are background galaxies distorted by the gravitational lens effect of the foreground cluster. The background galaxy shows several spots that are supernovas occurring in the galaxy. Please see the explanation for more detailed information.
图像显示了一个带有异常弧线的星系团。这些弧线是受前景星系团引力透镜效应扭曲的背景星系。背景星系中出现了几个斑点，这些斑点是星系中发生的超新星爆发。有关更多详细信息，请参阅说明。
A large spiral galaxy appears with stars in the foreground and smaller galaxies far in the background. The picturesque spiral has dark dust lanes between blue arms. Please see the explanation for more detailed information.

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。
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。
