Where did Henrietta Swan Leavitt work?
Henrietta Swan Leavitt (/ˈlɛvɪt/; July 4, 1868 – December 12, 1921) was an American astronomer. A graduate of Radcliffe College, she worked at the Harvard College Observatory as a “computer”, tasked with examining photographic plates in order to measure and catalog the brightness of stars.
What stars did Henrietta Swan Leavitt discover?
Leavitt’s outstanding achievement was her discovery in 1912 that in a certain class of variable stars, the Cepheid variables, the period of the cycle of fluctuation in brightness is highly regular and is determined by the actual luminosity of the star.
What was Henrietta Swan Leavitt famous for?
Henrietta Swan Leavitt’s contribution to the field of astronomy is that she gave us the tools to map out the stars in the universe. She discovered the correlation between Period and Luminosity. This helped turn the sky into a three-dimensional map allowing astronomers to solve the unknown in the equation: Distance.
When did Henrietta Swan Leavitt contribute to astronomy?
Leavitt is best known for discovering about 2,400 variable stars between 1907 and 1921 (when she died). She discovered that some of these stars have a consistent brightness no matter where they are located, making these so-called Cepheid variables a good measuring stick for astronomical distances.

Did Henrietta Swan Leavitt have kids?

Was Annie Jump Cannon deaf?
They didn’t want to give her awards because she was a woman and deaf. She finally got an award from Harvard at the end of her career. It was the William Cranch Bond Astronomer Award. She died three years later on April 13, 1941.
Who discovered standard candle?
Henrietta Swan Leavitt
The first discovered standard candles are cepheid variables, stars whose period of variation in luminosity can be translated into a distance. These were first identified by Henrietta Swan Leavitt in 1908, and more conclusively established in 1912.
Who discovered the distance in space?
Henrietta Leavitt, while working at Harvard College’s observatory in the early 20th century, discovered a way to measure distances between stars, which led astronomers to calculate the size of the universe.

Why was Annie Jump Cannon deaf?
She was a deaf female astronomer. Annie developed the Harvard Classification Scheme which classifies stars based on their temperatures. Annie was born hearing, but when she was around 30 years old, she got the scarlet fever that caused her to be profoundly deaf.
Why did Henry Norris Russell reject Cecilia Payne’s thesis?
