你们喜欢哪个版本的眉月星云？

天鹅座脑花星云NGC6888（眉月星云），距离我们约4800光年。一颗濒死的大质量恒星，用高速星风雕刻出这片如同大脑褶皱的宇宙气泡。红色是电离氢气，外围淡淡的蓝边来自氧的辐射，几十万年后，这颗恒星将迎来超新星爆发。 Cygnus' Brain‑Cloud Nebula, NGC 6888 (Crescent Nebula), lies roughly 4,800 light‑years away from Earth. A dying massive star carves out this cosmic bubble with brain‑fold‑like textures via its high‑speed stellar wind. The red glow comes from ionized hydrogen, while its faint bluish outer rim originates from oxygen emission. In hundreds of thousands of years, this star will end its life in a supernova explosion.
