恒星天文学

物质及其结构的这种一致性，也许是恒星天文学上的最惊人的发现。

This uniformity of material and structure is perhaps the most striking discovery of stellar astronomy .

本文介绍了由地球人造卫星进行天体测量的两项计划，并提出了它们对天体测量学、天体物理学和恒星天文学的影响。

Two projects for astrometry from Earth satellites are described and their impact on astrometry , astrophysics and stellar astronomy are outlined .

本文对按经典方法确定恒星统计视差这一重要恒星天文学问题作了简单的回顾，并指出这种方法在统计学上是不严格的。

The classical technique for determination of statistical parallaxes of stars , an important problem on stellar astronomy , is briefly reviewed , and it is pointed out that the technique is somewhat inaccurate in statistics .

恒星发出热量和不可见光，所以我们能看到它们，而地球与恒星不同，从天文学上讲，地球很冷，所以其自身并不发光。

Unlike stars , which are hot and glow invisible light so we can see them , our planet is , astronomically speaking , pretty cold . So it doesn 't really glow .
