Radio’s Guide to the Universe

StarDate announcer Sandy WoodStarDate debuted in 1978, making it the longest-running national radio science feature in the country. It airs on more than 300 radio stations.

StarDate tells listeners what to look for in the night sky, and explains the science, history, and skylore behind these objects. It also keeps listeners up to date on the latest research findings and space missions. And it offers tidbits on astronomy in the arts and popular culture, providing ways for people with diverse interests to keep up with the universe.

StarDate is a production of The University of Texas McDonald Observatory, which also produces the Spanish-language Universo Online web site and the bi-monthly StarDate magazine.

Today on StarDate

May 21-27: Sightseeing

We’ll visit a region of Mars that might have some of the best sights in the solar system, including giant volcanoes and a system of canyons that dwarf the Grand Canyon. Join us for Tharsis Ridge and much more.

May 28-June 3: Cosmic hazards

The Sun is getting especially quiet, so it produces fewer outbursts that could damage orbiting satellites. But that lets in a threat from outside the solar system. Join us for cosmic rays and much more.
