你看到图像中心右下方的那个蓝色斑点了吗？天文学家认为，它显示了1700年前一颗大质量恒星爆炸成为超新星的地方，它的光线到达了地球。该图像结合了夏威夷PanSTARRS望远镜的光学数据（红色，绿色和蓝色的背景恒星），南非MeerKAT望远镜的无线电（大红色云）以及美国宇航局钱德拉x射线天文台和欧洲航天局xmm -牛顿的x射线（蓝色显示）。这片巨大的云团是一个名为人马座C的恒星形成区，其范围约为50光年，距离地球约26,000光年。它距离银河系中心的超大质量黑洞（在图像的左边）只有260光年。如果这个蓝色斑点被证实是超新星遗迹，它将是迄今为止发现的离银河系中心最近的物体之一。在这个密集的区域，大质量恒星的死亡通过气体和磁场以一种复杂的方式与新恒星的诞生联系在一起。

Do you see that blue blob to the lower right of the image center? Astronomers think that it shows where a massive star exploded as a supernova whose light reached Earth 1,700 years ago. The image combines optical data from the PanSTARRS telescopes in Hawaii (background stars in red, green, and blue), radio from the MeerKAT telescope in South Africa (large red cloud) and X-rays from NASA's Chandra X-ray Observatory and ESA’s XMM-Newton (shown in blue). The large cloud is a star forming region called Sagittarius C, which is approximately 50 light-years in extent and about 26,000 light-years from Earth. It is located only about 260 light-years from the supermassive black hole in the center of the Galaxy (off to the left of the image). If the blue blob is confirmed to be a supernova remnant, it would be one of the closest ever discovered to the Galactic Center. In this dense region, the deaths of massive stars are connected to the birth of new stars through gas and magnetic fields in a complex way.
