在这张来自智利的美国国家科学基金会-能源部维拉·c·鲁宾天文台的图像的中央面板上有超过50万个星系。这是宇宙场，一块比满月大几倍的天空，最初是由哈勃观测到的。韦伯和其他望远镜也观测到了它，因为它包含了相对较少的来自我们银河系的明亮恒星，为银河系以外的其他星系提供了相对畅通的视野。外部面板编号为1-10，显示了中央面板中高亮显示的相应小区域的放大视图。星系形状和大小的变化是惊人的。其中一些非常遥远，它们发出的光在到达地球之前已经传播了数十亿年。鲁宾将每隔几天回到COSMOS领域，作为其十年空间和时间遗产调查的一部分。它将允许对宇宙场和天空如何随时间变化的动态视图。

There are more than half a million galaxies in the central panel of this image from the NSF-DOE Vera C. Rubin Observatory in Chile. This is the COSMOS field, a patch of sky several times larger than the full moon, first observed by Hubble. It has also been observed by Webb and other telescopes because it contains comparatively few bright stars from our own galaxy, offering a relatively unimpeded view of other galaxies outside the Milky Way. The outer panels, numbered 1-10, show zoomed-in views of the corresponding small regions highlighted in the central panel. The variety of galaxy shapes and sizes is astonishing. Some of them are so far away that their light has traveled for billions of years before reaching Earth. Rubin will come back every couple of days to the COSMOS field as part of its ten-year Legacy Survey of Space and Time. It will allow a dynamic view of the COSMOS field and how the sky changes over time.
