Carl Sagan Day is an annual celebration of the life and work of Carl Sagan, one of the most beloved scientists of the twentieth century. It honors his lasting influence on astronomy, science education, and the way ordinary people connect with the universe.

It falls on November 9th, Sagan's birthday. On this day, science centers, universities, and space fans mark his memory by sharing his ideas and celebrating the sense of wonder he was famous for.
