Abstract Image

红宝石是世界
作为图像集合的一部分,一张令人着迷的室女座星系团的照片(图中)被公布,室女座星系团是最近的星系团,距离约16 Mpc。这张照片是由3200万像素的LSST相机拍摄的,在7个晚上的调查模式下,只花了10.5个小时就完成了,覆盖了满月面积的45倍。由于像素数量庞大,人眼无法分辨图像中的所有特征,需要400个UHD电视屏幕才能以原始分辨率显示这样的图像,才能用我们自己的眼睛欣赏它的美。鲁宾的任务是在接下来的10年里每天晚上收集这些图像,作为初步调查。这张照片展示了各种迷人的特征。我们银河系中的蓝色、黄色和红色恒星以独特的交叉图案显示在前景中,而暗淡的红色星系出现在背景中。在四个面板中显示的放大图像显示了其他细节。左上角的面板展示了一个复杂的环境,包括由恒星流(RSCG 55),双螺旋星系(NGC 4411a和b),弥散星系和星团连接的合并星系。左下角聚焦于星系NGC 4519,突出的蓝色旋臂表明活跃的恒星形成。右上方的面板显示了NGC 4257周围的动态节奏,在这个框状区域内包含了大约1000万个星系。最后,右下角的图像展示了NGC 4378,一个被微弱光环包围的单臂螺旋星系。
