"A straight line can readily be drawn among each of the two series of points corresponding to maxima and minima, thus showing that there is a simple relation between the brightness of the variables and their periods."

What did Edwin hubble and henrietta leavitt work on?
Henrietta Swan Leavitt is one of the greatest women to work in astronomy. Because of the distinction between men and women in the 1900's - she was not even allowed to work a telescope.She was classified as nothing more than a human computer, but her work pivoted the discovery of the period luminosity relation of Cepheid variables.This provided an important yardstick for measuring distances in the Universe, which was lacking at the time.Even though she made one of the greatest breakthroughs in astronomy, she was not credited with it, Edwin Hubble took it!!
Why was Henrietta Swan Leavitt's study of these stars important in the area of astronomy?
Henrietta Leavitt studied Cepheid variables, a certain type of variable star with brightness that varies in a very regular cycle. By studying Cepheid variables in the Magellanic clouds, she discovered a simple relationship between the brightness of a Cepheid variable star and the length of time the cycle takes to repeat itself. To do this she used the fact that all such variables in the clouds are at the same distance from us, approximately. This allowed her to calculate the absolute magnitude of the star just by measuring the time period of the variation in brightness. The importance of this technique is that Cepheid variables can be found in more distant galaxies, and this provides a yardstick for finding out how far away they are. All you have to do is find a Cepheid variable in a galaxy and measure its variation period, then you know its absolute magnitude. You already know its apparent magnitude so it becomes possible to calculate how far away it is. This is one of the methods that astronomers used in the early 20th century to reveal the unexpectedly huge distances of other galaxies in the universe. Let's hear it for Miss Henrietta Leavitt!
