NGC 7424 is a barred spiral galaxy located 37.5 million light-years away in the southern constellation Grus (the Crane). Its size (about 100,000 light-years) makes it similar to our own galaxy, the Milky Way. [3] It is called a "grand design" …

NGC 7424 是一個位於南天星座 天鹤座 的 棒旋星系，距離地球約3750萬光年。 它的結構和直徑（約10萬光年）與 銀河系 相當類似 [3]。 該星系因為螺旋臂結構相當明顯，因此被稱為「宏觀螺旋星系」。 在該星系中發現了一顆 超新星 和兩個X射線超量源。 NGC 7424的形態介於一般螺旋星系（SA）和有明顯棒狀結構的棒旋星系（SB）之間。 其他的特徵包含它的中心有一個環狀結構，並且核心亮度低於螺旋臂。 偏紅色的棒狀結構代表 較古老的恆星 分布其中；而較鬆散的螺 …

2013年1月8日 · Explanation: The grand, winding arms are almost mesmerizing in this face-on view of NGC 7424, a spiral galaxy with a prominent central bar. About 40 million light-years distant in the headlong constellation Grus, this island universe is also about 100,000 light-years across making it remarkably similar to our own Milky Way.

NGC 7424 is a barred spiral galaxy located 37.5 million light-years away in the southern constellation Grus (the Crane). Its size (about 100,000 light-years) makes it similar to our own galaxy, the Milky Way.

Infrequently imaged, NGC 7424, is a “grand design” barred spiral galaxy 37.5 million light-years away in constellation Grus. It’s similar in size to our Milky Way at about 100,000 light-years. Website: https://www.astrobin.com/users/dstern/

2018年4月26日 · Seventeen years ago, astronomers witnessed supernova 2001ig go off 40 million light-years away in the galaxy NGC 7424, in the southern constellation Grus, the Crane. Shortly after SN 2001ig exploded, scientists photographed the supernova with the European Southern Observatory’s Very Large Telescope (VLT) in 2002.

NGC 7424 is a barred spiral galaxy located 37.5 million light-years away in the southern constellation Grus (the Crane). Its size (about 100,000 light-years) makes it like our own galaxy, the Milky Way. It is called a "grand design" galaxy because of its well defined spiral arms.

2022年10月4日 · NGC 7424 is a barred spiral galaxy located 37.5 million light-years away in the southern constellation Grus. Its size (about 100,000 light-years) makes it similar to the Milky Way and its well defined spiral arms make it called a "grand desigh" galaxy. NGC 7424 is intermediate between normal spirals (SA) and strongly barred galaxies (SB).

Abstract: We have studied the face-on, barred spiral NGC 7424 (site of the rare Type IIb SN 2001ig) with Chandra, Gemini and the Australia Telescope Compact Array. After giving revised X-ray colours and luminosity of the supernova, here we focus on some other interesting sources in the galaxy: in particular, our serendipitous discovery of two ...

NGC 7424 是一个位于南天星座 天鹤座 的 棒旋星系 ，距离地球约3750万光年。 它的结构和直径（约10万光年）与 银河系 相当类似 [3] 。 该星系因为螺旋臂结构相当明显，因此被称为“ 宏观螺旋星系 ”。 在该星系中发现了一颗 超新星 和两个X射线超量源。 NGC 7424的形态介于一般螺旋星系（SA）和有明显棒状结构的棒旋星系（SB）之间。 其他的特征包含它的中心有一个环状结构，并且核心亮度低于螺旋臂。 偏红色的棒状结构代表 较古老的恒星 分布其中；而较松散的螺旋臂 …
