查询词典 supernovae

The new technique reduced the distance ladder to three "rungs":(1) The distance to galaxy NGC4258 is measured using straightforward geometry and Kepler's laws;(2)Cepheids in six more distant galaxies are used to calibrate the luminosity of Type Ia supernovae;(3) The Hubble constant is measured by observing a brighter milepost marker, Type Ia supernovae, in more distant galaxies hundreds of millions of light-years away, embedded in the expanding universe.

这种新技巧简化了距离跳跃为三个"阶梯"：1、星系NGC 4258的距离采用开普勒定律和简单直接的几何方法精确测量；2、在6个更远的星系中的造父变星用来校准Ia超新星的光度；3、深嵌于数亿光年外的膨胀宇宙中的星系中的Ia超新星——一种遥远而明亮的量天尺，被用于精确测定哈勃常数。
