" Var" here stands for " variable." Hubble had found a variable star in the Andromeda Nebula.

“Var”在这里代表“变星”。哈勃望远镜在仙女座星云中发现了一颗变星。

For instance, back in 1912, the American astronomer Vesto Slipher was studying the spectrum of a fuzzy little spot in the sky that he called the Andromeda Nebula.

例如，早在 1912 年，美国天文学家维斯托·斯莱弗正在研究天空中一个模糊的小斑点的光谱，他称之为仙女座星云。

This is a plate that Hubble took back in 1923 of an object known at the time as the Andromeda Nebula.

这是哈勃望远镜于 1923 年取回的一个当时称为仙女座星云的天体的板块。

Hubble knew that if he studied how that star changed with time, he could measure the distance to the Andromeda Nebula, and when he did, the results were astonishing.

哈勃知道，如果他研究这颗恒星如何随时间变化，他就可以测量到仙女座星云的距离， 当他这样做时， 结果是惊人的。
