说明: 这幅来自韦伯太空望远镜近红外相机的拼接深场影像，呈现了星系团Abell 2744的壮丽身影。位在玉夫座方向、距离约35亿光年、亦称为潘朵拉星系团的Abell 2744，似乎是由三个独立的大质量星系团合併而成的巨型天体。在其内主宰性暗物质的影响下，这个巨型星系团翘曲和扭曲了时空结构，并以重力透镜会聚了更遥远天体的光。影像中许多比潘朵拉星系团星系更红、被拉伸及扭曲成弧形的透镜光源，是非常遥远的早期宇宙星系。想当然耳，带着衍射芒的天体是近在银河系内的前景恒星。以潘朵拉星系团的估计距离来换算，这幅影像所呈现的宇宙空间之跨幅约为600万光年。不过别着急，你可以透过这部长2分钟的影片探索这个迷人的区域。（Pandora's Cluster of Galaxies 潘朵拉星系团）

Explanation: This deep field mosaicked imagepresents a stunning view of galaxy cluster Abell 2744 recorded bythe James Webb Space Telescope's NIRCam.Also dubbed Pandora's Cluster, Abell 2744 itselfappears to be a ponderous merger of three different massive galaxyclusters.It lies some 3.5 billion light-years away, toward the constellation Sculptor.Dominated by dark matter,the mega-cluster warps and distortsthe fabric of spacetime,gravitationally lensingeven more distant objects.Redder than the Pandora cluster galaxiesmany of the lensed sources are very distant galaxies in the earlyUniverse, their lensed images stretched and distorted into arcs.Of course distinctivediffraction spikes mark foreground Milky Waystars.At the Pandora Cluster's estimateddistance this cosmic box spans about 6 million light-years.But don't panic.You can explore the tantalizing region in a2 minute video tour.
