詹姆斯-韋伯太空望遠鏡拍攝的這組壯觀的馬賽克影像,窺視著年輕星團 NGC 1333 的中心。這個星團距離英仙座僅 1000 光年,位於英仙座大型分子云的邊緣。韋伯望遠鏡對這一區域進行了深入探索,以識別低質量褐矮星和自由漂浮的行星,它的組合視場橫跨塵土飛揚的星團動盪的恆星育兒室近 2 光年。事實上,已知 NGC 1333 中蘊藏著不到一百萬年的恆星,不過大部分都被無處不在的星塵遮擋住了,無法被光學望遠鏡發現。這種混亂的環境可能與我們的太陽在 45 億年前形成時的環境相似。
原文:This spectacular mosaic of images from the James Webb Space Telescope peers into the heart of young star cluster NGC 1333. A mere 1,000 light-years distant toward the heroic constellation Perseus, the nearby star cluster lies at the edge of the large Perseus molecular cloud. Part of Webb's deep exploration of the region to identify low mass brown dwarf stars and free floating planets, the space telescope's combined field of view spans nearly 2 light-years across the dusty cluster's turbulent stellar nursery. In fact, NGC 1333 is known to harbor stars less than a million years old, though most are hidden from optical telescopes by the pervasive stardust. The chaotic environment may be similar to one in which our own Sun formed over 4.5 billion years ago.
