Vera Rubin confirmed the existence of dark matter and spoke up for equality
Credit: Carnegie Institution for ScienceThe Vera C. Rubin Observatory, under construction in Chile, is scheduled to begin scientific operations in 2023. Its ten-year Legacy Survey of Space and Time hopes to “see more of the universe than all previous telescopes combined”.
Also apt is that the first woman to have a large observatory named after her was an ardent advocate for equality in astronomy, and in society. A role model for many, Rubin overcame high cultural barriers to succeed in observational astronomy., documents her many accomplishments. The authors, astronomers Jacqueline Mitton and Simon Mitton, tell of how Rubin was born into an immigrant family in Philadelphia, Pennsylvania.
A few years later, she made confirmatory observations with colleague Kent Ford, who had developed electronic technology that improved the performance of even modest telescopes. These precision measurements gave cosmologists the evidence they needed for the existence of dark matter, and for how it settles like haloes around galaxies, providing the gravitational pull to keep them stable.
