Vera Rubin: Astronomy Pioneer

Vera Rubin passed away on December 26, 2016, aged 88. She was a pioneer in the male-dominated world of astronomy, notable for her original work on dark matter,  galaxy rotation and galaxy clumping.

From Popular Science:

Vera Rubin, who essentially created a new field of astronomy by discovering dark matter, was a favorite to win the Nobel Prize in physics for years. But she never received her early-morning call from Stockholm. On Sunday, she died at the age of 88.

Rubin’s death would sadden the scientific community under the best of circumstances. Countless scientists were inspired by her work. Countless scientists are researching questions that wouldn’t exist if not for her work. But her passing brings another blow: The Nobel Prize cannot be awarded posthumously. The most prestigious award in physics will never be bestowed upon a woman who was inarguably deserving.

In the 1960s and ’70s, Rubin and her colleague Kent Ford found that the stars within spiral galaxies weren’t behaving as the laws of physics dictated that they should. This strange spinning led her and others to conclude that some unseen mass must be influencing the galactic rotation. This unknown matter—now dubbed dark matter—outnumbers the traditional stuff by at least five to one. This is a big deal.
