天体的

A bit of mould is a pleiad of flowers;a nebula is an ant-hill of stars.

粒霉菌簇美不胜收的花朵，撮星云无数天体的蚁。

As a coelostat, MA tracks the motion of celestial objects observed at their meridian passages.

MA定天镜跟踪天体的运动，望远镜在天体中天前后进行观测。

Bright ejecta rays such as these are produced as impacts excavate and eject relatively unweathered subsurface material.

这些放射状陨石坑产生于天体撞击溅出的地下物质，绵延在遍布陨石坑的星表面数百公里。

As described above, the collapse of a rotating cloud of gas and dust leads to the formation of an accretion disk through which matter is channeled onto a central protostar.

部分的重力能量在崩溃的过程中会以红外线的形式损失掉，其馀的则会用于增加天体核心的温度。

If the incoming projectile were a white dwarf—a superdense star that packs the mass of the sun into a body a hundredth the size—the residents of Earth would be treated to quite a fireworks show.

如果接近的天体白矮星（whitedwarfstar，种超密恒星，质量约等同于太阳，但其体积却不到太阳的百万分之），那麽地球上的居民将可以看到场壮丽的烟火秀。
