Patrick Wiggins loves the night sky.
After 26 years at the Hansen Planetarium and the past 12 years as a volunteer Solar System Ambassador, Wiggins will receive NASA's Distinguished Public Service Medal, the same award given to astronomer Carl Sagan, sci-fi writer Robert Heinlein and 'Star Trek' creator Gene Roddenberry.
On Tuesday at 12:15 p.m., Wiggins and Tribune astronomy reporter Sheena McFarland join Jennifer Napier-Pearce to talk about Wiggins' honor, his continuing fascination with the stars and the future of space exploration.
