Vera Rubin, the woman who discovered the first evidence of dark matter, has died at 88

Vera Rubin, the astrophysicist responsible for confirming the first existence of dark matter, died on Sunday night at the age of 88.

Carnegie Institution president Matthew Scott called Rubin “a national treasure as an accomplished astronomer and a wonderful role model for young scientist.”

Rubin and her colleagues observed galaxies in the 1970s, they learned the motion of stars is a result of a “material that does not emit light and extends beyond the optical galaxy” — also known as dark matter.

Swiss astrophysicist Fritz Zwicky proposed the idea of dark matter in 1933, but Rubin’s groundbreaking work subsequently led to the confirmation of the material.

This finding is what led to the discovery that 90% of the universe is made up of dark matter, a finding some colleagues felt was overlooked and deserving of a Nobel Prize. Read more
