- Type Ia supernovae are so luminous that they outshine their host galaxies for several weeks. - Ia型超新星如此之亮,以至于在几个星期内它的寄主星系的光芒也相形见绌。 
- The observations also show for the first time that a white dwarf can create a cavity around it before blowing up in a Type Ia event. - 观测结果还首次显示,白矮星在爆炸成为Ia型超新星之前,会在其周围创造一个空洞。 
- Astronomers know that each Type Ia explosion has about the same brightness. - 天文学家知道每种类型的Ia超新星的爆炸亮度相差无几。 
- Researchers first observed accelerated expansion by studying Type Ia supernovae-the explosive deaths of White Dwarf stars. - 研究人员在研究Ia型超新星——白矮星爆炸中的消亡过程时首度观察到加速的膨胀。 
- Type Ia supernovae all explode with nearly the same amount of energy and therefore have almost the same intrinsic brightness. - Ia超新星爆发时辐射的能量几乎相等,因而具有几乎相同的本征亮度。
