It is the spiral galaxy NGC 4603, the most distant galaxy in which Cepheid variables have been found.
本图是其中一个星系：漩涡星系ngc 4603，本报告中发现造父变星的最远星系。
NASA Hubble Space Telescope (HST) view of the magnificent spiral galaxy NGC 4603, the most distant galaxy in which a special class of pulsating stars called Cepheid variables have been found.
哈勃太空望远镜(HST)拍摄的壮丽的漩涡星系ngc 4603，现今发现一类特殊的变星——造父变星的最远的星系。
This was accomplished by observing Cepheid variables at optical wavelengths out to greater distances than obtained previously and comparing those to similar measurements from ground-based telescopes.
这是通过观测比先前远得多的造父变星的可见光谱实现的，结果与地面望远镜观测结论类似。
On the colour-magnitude diagram they are situated near and more left than the hotter edge of the Cepheid instability stripe, so their temperature is higher than other types of pulsating variables.
在色星等图上，处于造父不稳定带的左外侧而温度较高，故简称热造父变星。
