To Henrietta Swan Leavitt (1868-1921)
Henrietta was an American astronomer, whose research made possible the first accurate determination of extragalactic distances. Her work helped to prove that galaxies were not part of the milky way but indeed were `` island universes``.
The distance between the stars; that empty space that separates us from other worlds, is an amazement for our society. Our galaxy, the milky way, is watching over billions of stars and in our vast universe in expansion there is an infinite number of galaxies like our own. If you have time one night, take a look at the stars around the tail of the Pegasus constellation, you'll find a blurry spot, then imagine that the blurry spot contains in itself billions of stars. Like an island in the univers.
Henrietta was truly a pioneer woman in humankind history, one of the first woman astronomer and scientist.
