网络 红移现象; 红移值; 红向移动
And redshift depends on just how the universe is expanding.
并且红移取决于宇宙如何膨胀。
Redshift 1 refers to when the universe was half its present age.
当宇宙为目前一半的年龄时的红移值为1。
The object´s apparent brightness yields the distance; its redshift yields the velocity.
这些天体的视亮度可以得到距离,它们的红移可以得出速度。
A decreased frequency is equivalent to a longer, or redder, wavelength. This is gravitational redshift.
较低了的频率,相当于较长或较红的波长,这就是红移。
"This galaxy is just beautiful," says Yuan. "Normally, galaxies at that redshift appear as blobs."
“这个星系很美丽,”Yuan如是说道,“通常,具有这么大红移量的星系只有小斑点那么大。”
