寄主星系
Examples
- Of the hosting galaxy , the
超新星爆发的 - These snapshots , taken by nasa ' s hubble space telescope , reveal five supernovae , or exploding stars , and their host galaxies
这些照片由nasa的哈勃空间望远镜拍摄，显示了五个超新星或者正在爆发的恒星，以及它们所在的星系。 - Furthermore , compared with supernova host galaxies , the hosts of long grbs are significantly fainter , more irregular and less endowed with heavy elements
还有，在比较超新星的宿主星系之后发现，长grb的宿主都非常黯淡，比较不规则，也较欠缺重元素。 - Astronomers found that certain kind of supernova outbursts could be used as a cosmic yardstick . by measuring the luminosity of these supernovae , accurate distances between the earth and the supernovae together with their host galaxies can be worked out
首先，天文学家发现某类超新星爆发可被视作宇宙的量天尺，只要测出超新星的光度，便能准确地测定超新星及其所在星系离我们多远。 - Astronomers painstakingly scan galaxies in the universe for type ia supernovae . if such supernovae are luckily found , the peak luminosities can be measured and hence the distances of the host galaxies from the earth can be determined
利用太空望远镜和其它先进的观测仪器，天文学家努力地在宇宙空间中搜索出现ia型超新星的星系，只要量度这些超新星的最大亮度，便可更准确地推算出星系跟地球间的距离。
