Vera Rubin

Vera Rubin was a renowned American astronomer, born in 1928, who made significant contributions to the field of astronomy. Her groundbreaking work focused on galaxy rotation rates, which led to a major breakthrough in understanding the behavior of galaxies. Through her research, Rubin identified a discrepancy between the predicted and observed angular motion of galaxies, shedding light on the galaxy rotation problem.

Rubin's pioneering findings, based on the study of galactic rotation curves, provided crucial evidence for the existence of dark matter. Her work was further corroborated by measurements from other astronomers, who used 21 centimeter hydrogen line radio telescopes to confirm her observations. Rubin's discovery played a pivotal role in advancing our understanding of the universe, and she remained a prominent figure in the field of astronomy until her passing in 2016.
