潘多拉星系團
Pandora's Cluster of Galaxies

這幅深場馬賽克影像展示了由詹姆斯-韋伯太空望遠鏡的 NIRCam 記錄的星系團 Abell 2744 的迷人景色。Abell 2744 星系團也被稱為潘多拉星系團，它本身似乎是由三個不同的大質量星系團合併而成的。它位於大約 35 億光年之外，朝向雕刻星座。在暗物質的支配下，這個超大星系團扭曲了時空結構，對更遙遠的天體產生了引力透鏡效應。比潘多拉星團星系更紅的許多透鏡源是早期宇宙中非常遙遠的星系，它們的透鏡影像被拉伸扭曲成弧形。當然，明顯的衍射尖峰標誌著前景銀河系恆星。根據潘多拉星團的估計距離，這個宇宙盒子的跨度大約為 600 萬光年。不過不要驚慌。您可以透過 2 分鐘的影片導覽來探索這個誘人的區域。
原文：This deep field mosaicked image presents a stunning view of galaxy cluster Abell 2744 recorded by the James Webb Space Telescope's NIRCam. Also dubbed Pandora's Cluster, Abell 2744 itself appears to be a ponderous merger of three different massive galaxy clusters. It lies some 3.5 billion light-years away, toward the constellation Sculptor. Dominated by dark matter, the mega-cluster warps and distorts the fabric of spacetime, gravitationally lensing even more distant objects. Redder than the Pandora cluster galaxies many of the lensed sources are very distant galaxies in the early Universe, their lensed images stretched and distorted into arcs. Of course distinctive diffraction spikes mark foreground Milky Way stars. At the Pandora Cluster's estimated distance this cosmic box spans about 6 million light-years. But don't panic. You can explore the tantalizing region in a 2 minute video tour.
