It features an engaging and informative series of two minute, factual episodes about asteroids, comets, spacecraft, and other objects in space.

The pieces are "evergreen" in that they are current but not dated.

The Travelers In The Night Pieces are written and produced by a member of the Catalina Sky Survey Team at the University of Arizona.

The Catalina Sky Survey has discovered nearly half of the Earth approaching objects known to exist.
