M78 is a beautiful reflection nebula in Orion. It is the brightest reflection nebula in the sky, according to Sky Safari. It lies 1600 ly away. NGC 2071 to its left is also a reflection nebula..It lies 550 ly. A small portion of Barnard's Loop appears in …

This is a list of NGC objects 7001–7840 from the New General Catalogue (NGC). The astronomical catalogue is composed mainly of star clusters, nebulae, and galaxies. Other objects in the catalogue can be found in the other subpages of the list of NGC objects.

NGC 7020 is a barred lenticular galaxy located about 140 million light-years away in the constellation Pavo. [3][4] NGC 7020 was discovered by astronomer John Herschel on August 31, 1836. [5] NGC 7020 has a large outer ring surrounding a bright inner hexagonal zone containing an inner ring and possibly a bar.

NGC 7020 是一个棒状 透镜状星系，位于 孔雀座，距离地球约1亿4千万 光年 [3][4]。 天文学家 约翰·赫歇尔 发现于1836年8月31日发现NGC 7020 [5]。 NGC 7020有一个巨大外环，围绕着内侧明亮的六边形区域，该区域包含一个内环，可能还有一条棒旋。 外环与星系内测的六边形区域完全分离，特征为无数絮状螺旋。 外还的估计直径为110,000光年 (33.6 kpc)。 该环比星系的其他部分更加多节且更偏蓝色，显示星系最近发生恒星形成的位置。 该星系似乎不含电离气体，这对于 …
