欧几里得任务的新图像包括一个由数千个遥远星系组成的星系团，展示了航天器的独特能力。
NGC 685占据了舞台的中心位置，在墨黑的背景上闪烁着微弱的恒星。这个星系显然是一个棒旋星系，它有明亮的中心棒和斑驳弯曲的旋臂。它距离我们大约5,800万光年，位于波江座。NGC 685位于天赤道以南，在一年中的某些时候从南半球可以看到。
这张NASA哈勃太空望远镜的新照片的前景是几片亮粉色和几缕暗红色。NGC 5068是一个棒旋星系，有数千个恒星形成区域和大量星际尘埃。

这张来自NASA詹姆斯·韦伯太空望远镜的HH 211的照片显示了一颗0级原恒星的外流，这颗原恒星是一颗类似太阳的年前恒星，当时它的年龄不超过几万年，质量只有现在太阳的8%（它最终会成长为一颗像太阳一样的恒星）。
This colorful image of the globular star cluster Terzan 12 is a spectacular example of how dust in space affects starlight coming from background objects. A globular star cluster is a conglomeration of stars, arranged in a spheroidal shape. Stars in globular clusters are bound together by gravity, with a higher concentration of stars towards the center. The ...

Voyager 1 and its twin, Voyager 2, were originally launched to conduct closeup studies of Jupiter and Saturn, Saturn’s rings, and the larger...
NASA的詹姆斯·韦伯太空望远镜已经开始研究最著名的超新星之一SN 1987A（超新星1987A）。SN 1987A位于16.8万光年之外的大麦哲伦星云中，自1987年2月被发现以来，近40年来一直是从伽马射线到无线电波长的密集观测目标。
The galaxy ESO 300-16 looms over this image from the NASA/ESA Hubble Space Telescope. This galaxy, which lies 28.7 million light-years from Earth in the constellation Eridanus, is a ghostly assemblage of stars which resembles a sparkling cloud. Other distant galaxies and foreground stars complete this astronomical portrait, which was captured by the Advanced...
