Explanation: Appropriately nicknamed "the Skull Nebula", planetary nebula NGC 246 really does surround a dying star some 1,600 light-years away in the constellation Cetus.

解释："骷髅星云"，形容行星状星云NGC 246的一个很合适的绰号，围绕着大约1600光年之外的鲸鱼座座的一颗正在死亡的恒星。

About 400 light-years away toward the constellation Cetus, Mira is presently too faint to be seen by the unaided eye, but will become visible again in mid-November.

Appropriately nicknamed "the Skull Nebula", planetary nebula NGC 246 really does surround a dying star some 1,600 light-years away in the constellation Cetus.

位在鲸鱼座离我们约1，600光年远的行星状星云NGC 246，有个骷髅星云的贴切昵称，因为它中心的确有一颗滨临死亡的恒星。

Now an international team of astronomers has finally observed the acceleration of protons within a shock wave. Using the Very Large Telescope in Paranal, Chile, and NASA's Chandra spacecraft, they measured the visible light and x-ray emissions of the remnant of a supernova about 8200 light-years away in the direction of the constellation Circinus.

现在，一个由天文学家组成的跨国研究小组终于观察到激波内部质子的加速情况，他们利用智利帕拉纳尔的甚大望远镜和美国国家航空航天管理局的钱德拉太空船，测量到了圆规座方向大约8，200光年处一颗超新星残骸发出的可见光和 X 射线。

But these galaxies, members of Hickson Compact Group 31, are relatively nearby, only 166 million light-years away.

但这些星系，希克森紧凑集团的31名成员，是较近，只有166亿光年之远。
