H. R. 3196


Begun and held at the City of Washington on Thursday,
the third day of January, two thousand and nineteen

    To designate the Large Synoptic Survey Telescope as the “Vera C. Rubin Observatory”.

Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled,

SECTION 1. Short title.

This Act may be cited as the “Vera C. Rubin Observatory Designation Act”.

SEC. 2. Findings.

Congress finds the following:

(1) Dr. Vera Rubin was born July 23, 1928, to Philip and Rose Applebaum Cooper.

(2) Dr. Rubin pursued her graduate studies at Cornell University and Georgetown University, earning her Ph.D. in Physics in 1954.

(3) Dr. Rubin’s Ph.D. thesis on galaxy motions provided supporting evidence that galaxies are not uniformly distributed, but exist in clusters.

(4) Dr. Rubin continued to study the motions of galaxies, first as research associate and assistant professor at Georgetown University, and then as a member of the staff at the Carnegie Institution of Washington Department of Terrestrial Magnetism.

(5) Dr. Rubin faced barriers throughout her career because of her gender.

(6) For instance, one of the world’s leading astronomy facilities at the time, the Palomar Observatory, did not permit women. Dr. Rubin persisted and was finally allowed to observe at Palomar in 1965, the first woman officially allowed to do so.

(7) In 1970, Dr. Rubin published measurements of the Andromeda galaxy showing stars and gas orbiting the galaxy’s center too fast to be explained by the amount of mass associated with the light output of the stars.

(8) In the years that followed, Dr. Rubin and her collaborators used their observations, in conjunction with the work by earlier astronomers on the rotation of stars in spiral galaxies, to provide some of the best evidence for the existence of dark matter.

(9) This work contributed to a major shift in the conventional view of the universe, from one dominated by ordinary matter such as what produces the light of stars, to one dominated by dark matter.

(10) Dr. Rubin was elected to the National Academy of Sciences in 1981, the second woman astronomer to be so honored.

(11) Dr. Rubin was awarded the President’s National Medal of Science in 1993 “for her pioneering research programs in observational cosmology which demonstrated that much of the matter in the universe is dark, and for significant contributions to the realization that the universe is more complex and more mysterious than had been imagined”.

(12) Dr. Rubin was an outspoken advocate for the equal treatment and representation of women in science, and she served as a mentor, supporter, and role model to many women astronomers throughout her life.

(13) The Large Synoptic Survey Telescope, funded jointly by the National Science Foundation and the Department of Energy, will honor the legacy of Dr. Rubin and her colleagues to probe the nature of dark matter by mapping and cataloging billions of galaxies through space and time.

SEC. 3. Designation.

The Large Synoptic Survey Telescope shall be known and designated as the “Vera C. Rubin Observatory”.

SEC. 4. References.

Any reference in a law, map, regulation, document, paper, or other record of the United States to the facility described in section 3 shall be deemed to be a reference to the “Vera C. Rubin Observatory”.


Speaker of the House of Representatives.  


Vice President of the United States and   
President of the Senate.
