WebIn 1912, Henrietta Swan Leavitt noted that 25 stars, called Cepheid stars, in the Magellanic cloud would brighten and dim periodically. Leavitt was able to measure the period of each star by measuring the timing of its ups and downs in brightness. What she determined was that the brighter the Cepheid, the longer its period. WebLeavitt became an accomplished variable star hunter, cataloguing 2,400 such stars during the course of her work – more than half the total known at the time. In analyzing the plates, Leavitt began to notice the brighter Cepheids exhibited a longer period of variability. Four years later, after further analysis, she surmised the brightness of ... twin turbo ford crate engine
