Update - StarDate radio celebrates its 40th birthday

40 Years and Counting!

StarDate is radio’s longest-running nationally aired science program. It began in 1977 as a daily telephone message service by McDonald Observatory. It was picked up by Austin radio station KLBJ-FM, and aired as “Have You Seen the Stars Tonight” beginning in June 1977. With a grant from the National Science Foundation the program became “Star Date,” and began airing nationally, seven days per week, on October 1, 1978. More »
