哈勃寻找一个不寻常的星系

哈勃寻找一个不寻常的星系




星系合并 Arp-Madore 417-391 在这张来自 NASA/ESA哈勃太空望远镜的图像中抢走了聚光灯。Arp-Madore 目录是分布在整个南部天空的特别奇特的星系的集合,包括微妙相互作用的星系以及更壮观的碰撞星系的集合。Arp-Madore 417-391 位于南天半球的波江座,距地球约 6.7 亿光年,就是这样的一次星系碰撞。这两个星系被引力扭曲并扭曲成一个巨大的环,使它们的核心并排依偎在一起。

哈勃望远镜使用其高级巡天相机 (ACS)捕捉了这一场景——该仪器经过优化,可以在古代宇宙中寻找星系和星系团。哈勃的 ACS 已经为科学发现做出了 20 年的贡献,在其整个生命周期中,它参与了从绘制暗物质分布图到研究星系团演化的方方面面。

该图像来自一系列哈勃观测,旨在创建一系列有趣的目标,供 NASA/ESA/CSA詹姆斯·韦伯太空望远镜以及其他地面望远镜进行后续观测。天文学家选择了一份以前未被观测到的星系列表,供哈勃望远镜在其他预定观测之间进行检查。随着时间的推移,这让天文学家在尽可能有效地利用哈勃有限的观测时间的同时,建立了一个有趣的星系动物园。
