心形的触须星系
2024年2月7日 The Heart Shaped Antennae Galaxies Image Credit & Copyright: Kent E. Biggs Explanation: Are these two galaxies really attracted to each other? Yes, gravitationally, and the result appears as an enormous iconic heart — at least for now. Pictured is the pair of galaxies cataloged as NGC 4038 and NGC 4039,known as the Antennae Galaxies. Beca...
Arp 87: 哈勃拍摄的合并中星系对
2023年10月24日 Arp 87: Merging Galaxies from Hubble Image Credit: NASA, ESA, Hubble; Processing: Harshwardhan Pathak Explanation: This dance is to the death. As these two large galaxies duel, a cosmic bridge of stars, gas, and dust currently stretches over 75,000 light-years and joins them. The bridge itself is strong evidence that these two immense star system...
NGC4676: 老鼠星系
2021年10月4日 NGC 4676: When Mice Collide Image Credit: NASA, ESA, Hubble; Processing & Copyright: William Ostling (The Astronomy Enthusiast) Explanation: These two mighty galaxies are pulling each other apart. Known as the “Mice” because they have such long tails, each spiral galaxy has likely already passed through the other. The long tails a...
NGC 520：哈勃拍摄的互撞星系
2021年9月7日 NGC 520: Colliding Galaxies from Hubble Image Credit: NASA, ESA, Hubble; Processing & Copyright: William Ostling (The Astronomy Enthusiast) Explanation: Is this one galaxy or two? The jumble of stars, gas, and dust that is NGC 520 is now thought to incorporate the remains of two separate disk galaxies. A defining component of NGC 520 — a...
哈勃影像：蝌蚪星系
2021年06月21日 The Tadpole Galaxy from Hubble Image Credit: Hubble Legacy Archive, ESA, NASA; Processing: Amal Biju Explanation: Why does this galaxy have such a long tail? In this stunning vista, based on image data from the Hubble Legacy Archive, distant galaxies form a dramatic backdrop for disrupted spiral galaxy Arp 188, the Tadpole Galaxy. The cosmic tadp...
UGC 1810： 狂乱互扰星系的哈勃望远镜影像
2020年10月18日 UGC 1810: Wildly Interacting Galaxy from Hubble Image Credit: NASA, ESA, Hubble, HLA; Processing & Copyright: Domingo Pestana Explanation: What’s happening to this spiral galaxy? Although details remain uncertain, it surely has to do with an ongoing battle with its smaller galactic neighbor. The featured galaxy is labelled UGC 1810 by ...
哈勃的海豚星系影像
2020 May 10 The Porpoise Galaxy from Hubble Image Credit: NASA, ESA, Hubble, HLA; Reprocessing & Copyright: Raul Villaverde Explanation: What’s happening to this spiral galaxy? Just a few hundred million years ago, NGC 2936, the upper of the two large galaxies shown, was likely a normal spiral galaxy — spinning, creating stars — and mi...
星系NGC 5394和NGC 5395的双人慢舞
2020 March 4 The Slow Dance of Galaxies NGC 5394 and 5395 Image Credit: Gemini, NSF, OIR Lab, AURA; Text: Ryan Tanner (NASA/USRA) Explanation: If you like slow dances, then this may be one for you. A single turn in this dance takes several hundred million years. Two galaxies, NGC 5394 and NGC 5395, slowly whirl about each other in a gravitational interaction...
