Explanation: Returning to science operations on June 14, the Hubble Space Telescope used its new pointing mode to capture this sharp image of spiral galaxy NGC 1546. A member of the Dorado galaxy group, the island universe lies a mere 50 million light-years away. The galactic disk of NGC 1546 is tilted to our line-of-sight, with the yellowish light of the old stars and bluish regions of newly formed stars shining through the galaxy’s dust lanes. More distant background galaxies are scattered throughout this Hubble view. Launched in 1990, Hubble has been exploring the cosmos for more than three decades, recently celebrating its 34th anniversary.

说明: 哈勃太空望远镜于6月14日重新上线进行科学观测，并利用其新的指向模式，在地球轨道上拍下了这张螺旋星系NGC 1546的清晰影像。作为剑鱼星系群成员之一的这个宇宙岛，距离我们仅有5,000万光年。NGC 1546的星系盘相对于我们的视线有点侧倾，因此透过其星系尘埃带，可见到后方年老恒星散发的黄光和泛蓝的新诞生恒星区。此外，在这片哈勃望远镜视野里，到处散布着更遥远的背景星系。自1990年升空运转以来，哈勃已探索宇宙超过了30年，并在最近欢渡了34周年庆。
