Vera Florence Cooper Rubin (/ ˈ r uː b ɪ n /; July 23, 1928 – December 25, 2016) was an American astronomer who pioneered work on galaxy rotation rates. [ 1 ] [ 2 ] She uncovered the discrepancy between the predicted and observed angular motion of galaxies by studying galactic rotation curves .
The Vera C. Rubin Observatory, formerly known as the Large Synoptic Survey Telescope (LSST), is an astronomical observatory under construction in Chile. Its main task will be carrying out a synoptic astronomical survey , the Legacy Survey of Space and Time .
In the late 1960s and early 1970s, Vera Rubin, an astronomer at the Department of Terrestrial Magnetism at the Carnegie Institution of Washington, worked with a new sensitive spectrograph that could measure the velocity curve of edge-on spiral galaxies to a greater degree of accuracy than had ever before been achieved.

She used galaxies' rotations to discover the first direct evidence of dark matter in the 1970s while working at the Carnegie Institution in Washington. Vera Rubin, pioneering U.S. dark matter ...
About her research article on this galaxy, Vera Rubin wrote: "I discovered from observations of NGC 4550 that in the single disk of this galaxy, half the stars orbit clockwise, and half the stars orbit counterclockwise, both systems intermingled. This observation required that many astronomers modify the manner in which they measured velocities ...

A major piece of evidence for the presence of dark matter in the Universe, discovered by Vera Rubin from observations of galactic rotation curves in the 1970s. Stars luminosity Henrietta Swan Leavitt was an American astronomer who discovered the relation between the luminosity and the period of Cepheid variable stars at the beginning of 20th ...
