这对合并的星系在红外波段明亮,距离海豚座约5亿光年。宇宙混搭的背景是更遥远的星系,偶尔还有尖尖的前景恒星。但在这张詹姆斯·韦伯太空望远镜拍摄的深空图像中,星系合并本身的跨度约为10万光年。图像数据来自韦伯的近红外相机(NIRCam)和中红外仪器(MIRI)。他们结合了清晰的红外图像,跟踪了星系尺度的重组,在尘埃合并的混乱的强烈的恒星形成区域和扭曲的螺旋臂中

Bright at infrared wavelengths, this merging galaxy pair is some 500 million light-years away toward the constellation Delphinus. The cosmic mashup is seen against a background of even more distant galaxies, and occasional spiky foreground stars. But the galaxy merger itself spans about 100,000 light-years in this deep James Webb Space Telescope image. The image data is from Webb's Near-InfraRed Camera (NIRCam) and Mid-InfraRed Instrument (MIRI). Their combined, sharp infrared view follows galactic scale restructuring in the dusty merger's wild jumble of intense star forming regions and distorted spiral arms
