NGC 6960
Witch's Broom Nebula (魔女のほうき星雲)
Veil Nebula (網状星雲)
Nb SNR


別名 (Other names)
LBN 191

星座 (Constellation)
はくちょう座 (Cyg) (Cygnus)


距離 (Distance)
1,400光年 (1,400 light-years)

網状星雲(あみじょうせいうん、Veil Nebula 、NGC6992-5、NGC6960)ははくちょう座ε星の3°から5°ほど南に東西に約3°の間隔で向かい合った半弧状の散光星雲。

明るい東側がNGC6992-5、西側がNGC6960であり、数万年前に爆発した超新星残骸のガスが毎秒100kmで広がっている姿だと考えられている。肉眼ではたいへん淡いがカラー写真にはよく写る。バーナードループに倣い白鳥ループ(Cygnus Loop )と呼ばれることがある。

Witch's Broom Nebula (NGC 6960) is a veil nebula located 1,400 light years from the Earth in the constellation Cygnus.

Ten thousand years ago, before the dawn of recorded human history, a new light must suddenly have appeared in the night sky and faded after a few weeks. Today we know this light was an exploding star and record the colorful expanding cloud as the Veil Nebula. Pictured above is the west end of the Veil Nebula known technically as NGC 6960 but less formally as the Witch's Broom Nebula. The expanding debris cloud gains its colors by sweeping up and exciting existing nearby gas. The supernova remnant lies about 1,400 light-years away towards the constellation of Cygnus. This Witch's Broom actually spans over three times the angular size of the full Moon. The bright star 52 Cygni is visible with the unaided eye from a dark location but unrelated to the ancient supernova.
