幽灵星云

The brightest stars embedded in nebulae throughout our galaxy pour out a torrent of radiation that eats into vast clouds of hydrogen gas – the raw material for building new stars. This etching process sculpts a fantasy landscape where human imagination can see all kinds of shapes and figures. This nebula in the constellation of Cassiopeia has flowing veils of gas and dust that have earned it the nickname “Ghost Nebula.”

Officially known as IC 63, this nebula is located 550 light-years away in the constellation Cassiopeia the Queen.

嵌在我们整个银河系星云中的最亮的恒星会释放出一股辐射流，这些辐射流会吞噬巨大的氢气云，而氢气是形成新恒星的原材料。这种蚀刻工艺塑造了一个幻想的景观，在那里人类的想象力可以看到各种各样的形状和图形。这颗位于仙后座的星云有着流动的气体和尘埃的面纱，因此有了“幽灵星云”的绰号。

这个星云的官方名称是IC 63，位于550光年之外的仙后座女皇座。
