美国航天局的Chandra X射线天文台 捕捉了一幅罕见的星系群合并图像 揭示了在激烈的宇宙碰撞中 热气和暗物质动态 NASA's Chandra X-ray Observatory captured a rare image of a merging galaxy cluster, revealing hot gas and dark matter dynamics during a violent cosmic collision.

美国宇航局钱德拉X射线天文台捕捉到了“香槟星系团”的新图像，这是一颗于2020年12月31日发现的罕见合并星系团。 NASA's Chandra X-ray Observatory has captured a new image of the "Champagne Cluster," a rare merging galaxy cluster discovered on December 31, 2020. 复合图像显示紫色的超热气体和彩色的光学数据,显示两个大团群碰撞,热气垂直伸展,暗物质发挥关键引力作用。 The composite image, showing superheated gas in purple and optical data in color, reveals two massive clusters colliding, with hot gas stretching vertically and dark matter playing a key gravitational role. 科学家们不确定合并是发生在大约4亿年前,还是发生在20多亿年前的先前碰撞中,随后是重新碰撞。 Scientists are uncertain whether the merger occurred about 400 million years ago or involved a prior collision over two billion years ago followed by a re-collision. 研究结果发表在《天体物理杂志》上,旨在揭示此类暴力宇宙事件期间的暗物质行为。 The findings, published in The Astrophysical Journal, aim to shed light on dark matter behavior during such violent cosmic events.
