For this week's Serene Sunday, American Astronomer, Dr. Vera Rubin’s wisdom bridges last week’s Earth Day theme with our continuous focus on all things astronomy. "Each one of you can change the world, for you are made of star stuff, and you are connected to the universe." Dr. Rubin changed our world and our understanding of the universe through her work studying galaxy rotation rates and then discovering the evidence for dark matter. She also blazed a path for women in science. Each one of us has the capability and the responsibility to care for ourselves, each other, and our planet. What does that look like for you? What will your legacy be?
