The renaming initiative was spearheaded last June by the chairwoman of the House Committee on Science, Space, and Technology, Rep. Eddie Bernice Johnson, D-Texas, and Rep. Jenniffer Gonzlez-Coln, R-Puerto Rico, and was signed into law by the president on December 20.The facility is designed to probe dark matter and dark energy, as well as the structure of the Milky Way, among other science questions, making it a perfect choice to bear Rubins name.Vera was not only a brilliant scientist whose groundbreaking discoveries are as relevant today as they were 50 years ago, she was also a tireless advocate for women in astronomy, added Richard Carlson, director of Carnegie Earth and Planets, where Rubin worked. She mentored several generations of women in science. This honor will ensure that her legacy inspires many more.This artistic rendering shows the Large Synoptic Survey Telescope (LSST) facilities, renamed the Vera C. Rubin Observatory, against a simulated night sky. Operations are scheduled to start in late 2022. The telescope will optically probe dark matter and dark energy, inventory the Solar System, and map the Milky Way. Image courtesy LSST, Todd Mason'
