NGC 1156 is a dwarf irregular galaxy in the Aries constellation of the type ibm. It is considered a Magellanic-type irregular. The galaxy has a larger than average core, and contains zones of contra-rotating gas. The counter-rotation is thought to be the result of tidal interactions with another gas rich galaxy some time in the past.

2022年8月22日 · Hubble has captured NGC 1156 before — this new image features data from a galactic gap-filling programme simply titled “Every Known Nearby Galaxy”. Astronomers noticed that only three quarters of the galaxies within just over 30 million light-years of Earth had been observed by Hubble in sufficient detail to study the makeup of the stars ...

NGC 1156 是 白羊座 的一個 星系。

2019年7月12日 · The galaxy NGC 1156 resembles a delicate cherry blossom tree flowering in springtime in this Hubble image. The many bright "blooms" within the galaxy are in fact stellar nurseries — regions where new stars are springing to life.

2019年7月8日 · The NASA/ESA Hubble Space Telescope has produced a beautiful image of the dwarf irregular galaxy NGC 1156, one of the best targets to study the isolated dwarf galaxies in the nearby Universe.

NGC 1156是 白羊座 的一个 星系，发现者是弗里德里希·威廉·赫歇尔，发现日期为1786年11月13日。 在这张 哈勃望远镜 拍摄的本周照片中，星系NGC1156类似于春天开花的一棵娇嫩的樱花树。 银河系中许多明亮的“花朵”实际上是恒星的托儿所，在那里新的恒星正在孕育生命。 新生恒星在这些区域发出的高能光向外流动，并与附近的氢气团相遇，使其发出特征性的粉红色光芒。 NGC1156位于白羊座（公羊星座）。 它被归类为一个不规则矮星系，这意味着它不像其他星 …

2022年9月4日 · 来自哈勃太空望远镜的一幅新照片捕获一个名叫ngc1156的不规则矮星系。ngc 1156位于白羊座距离地球2500万光年，吹捧一个不同于大多数其它星系的独特结构-----按照来自这次使命的合作伙伴欧洲航天局的一份声明，它是“一个星系形变学的奇迹”。

2022年8月22日 · This Hubble image shows NGC 1156, a dwarf irregular galaxy located 25 million light-years away in the constellation of Aries. The color image was made from separate exposures taken in the ultraviolet, visible and near-infrared regions of the spectrum with Hubble’s Wide Field Planetary Camera 2 (WFPC2) and Advanced Camera for Surveys (ACS).
