The sands of time are running out for the central star of this hourglass-shaped planetary nebula.
在这一酷似沙漏形状的星云内，“时间之沙”即将从中央星之中流逝殆尽。
Hubble's sharp view is able to resolve patterns and ripples in the nebula very close to the central star that is not visible from the ground.
借助于先进的观测成像设备，“哈勃”拍摄到与中部恒星非常靠近区域出现的图案和波纹，而这些都是在地面上无法观测到的。
IRAS 23166 + 1655 is just starting this process and the central star has yet to emerge from the cocoon of enveloping dust.
IRAS 23166 + 1655恰好处于这个过程的开端，而中央的恒星也正在从蚕茧一般的尘埃中显露出来。
Shining with light from the central star reflected by dust, the frigid Boomerang Nebula is believed to be a star or stellar system evolving toward the planetary nebula phase.
冰寒的回飞棒星云会发光，是因为它尘埃反射了来自中心星的星光，天文学家认为它是正在演化到行星状星云阶段的恒星或恒星系统。
With this distinctive central star-forming ring, and the addition of numerous bluish clusters of hot, young stars dotted through its spiral arms, NGC 1097 makes a stunning visual object.
有着与众不同的中心恒星环，旋臂上还点缀着大量炽热的年轻恒星组成的蓝巨星簇，NGC 1097就成为绝佳的观测目标。
In only a few thousand years the nebula will dissipate into space. The central star will then gradually cool down, eventually becoming a White Dwarf, the final stage of evolution for nearly all stars.
在仅仅的几千年里，星云将消散在太空中，中心的恒星将完全冷却下来，最后变成白矮星，这是几乎所有恒星演化的最后阶段。
